Latex Posters

LaTeX Research Posters

Overview

Research posters are a critical medium for scientific communication at conferences, symposia, and academic events. This skill provides comprehensive guidance for creating professional, visually appealing research posters using LaTeX packages. Generate publication-quality posters with proper layout, typography, color schemes, and visual hierarchy.

When to Use This Skill

This skill should be used when:

• Creating research posters for conferences, symposia, or poster sessions
• Designing academic posters for university events or thesis defenses
• Preparing visual summaries of research for public engagement
• Converting scientific papers into poster format
• Creating template posters for research groups or departments
• Designing posters that comply with specific conference size requirements (A0, A1, 36×48", etc.)
• Building posters with complex multi-column layouts
• Integrating figures, tables, equations, and citations in poster format

AI-Powered Visual Element Generation

STANDARD WORKFLOW: Generate ALL major visual elements using AI before creating the LaTeX poster.

This is the recommended approach for creating visually compelling posters: 1. Plan all visual elements needed (title, intro, methods, results, conclusions) 2. Generate each element using scientific-schematics or Nano Banana Pro 3. Assemble generated images in the LaTeX template 4. Add text content around the visuals

Target: 60-70% of poster area should be AI-generated visuals, 30-40% text.

CRITICAL: Preventing Content Overflow

⚠️ POSTERS MUST NOT HAVE TEXT OR CONTENT CUT OFF AT EDGES.

Common Overflow Problems: 1. Title/footer text extending beyond page boundaries 2. Too many sections crammed into available space 3. Figures placed too close to edges 4. Text blocks exceeding column widths

Prevention Rules:

1. Limit Content Sections (MAXIMUM 5-6 sections for A0):

✅ GOOD - 5 sections with room to breathe:
   - Title/Header
   - Introduction/Problem
   - Methods
   - Results (1-2 key findings)
   - Conclusions

❌ BAD - 8+ sections crammed together:
   - Overview, Introduction, Background, Methods, 
   - Results 1, Results 2, Discussion, Conclusions, Future Work

2. Set Safe Margins in LaTeX:

% tikzposter - add generous margins
\documentclass[25pt, a0paper, portrait, margin=25mm]{tikzposter}

% baposter - ensure content doesn't touch edges
\begin{poster}{
  columns=3,
  colspacing=2em,           % Space between columns
  headerheight=0.1\textheight,  % Smaller header
  % Leave space at bottom
}

3. Figure Sizing - Never 100% Width:

% Leave margins around figures
\includegraphics[width=0.85\linewidth]{figure.png}  % NOT 1.0\linewidth

4. Check for Overflow Before Printing:

# Compile and check PDF at 100% zoom
pdflatex poster.tex

# Look for:
# - Text cut off at any edge
# - Content touching page boundaries  
# - Overfull hbox warnings in .log file
grep -i "overfull" poster.log

5. Word Count Limits:

• A0 poster: 300-800 words MAXIMUM
• Per section: 50-100 words maximum
• If you have more content: Cut it or make a handout

---

CRITICAL: Poster-Size Font Requirements

⚠️ ALL text within AI-generated visualizations MUST be poster-readable.

When generating graphics for posters, you MUST include font size specifications in EVERY prompt. Poster graphics are viewed from 4-6 feet away, so text must be LARGE.

⚠️ COMMON PROBLEM: Content Overflow and Density

The #1 issue with AI-generated poster graphics is TOO MUCH CONTENT. This causes:

• Text overflow beyond boundaries
• Unreadable small fonts
• Cluttered, overwhelming visuals
• Poor white space usage

SOLUTION: Generate SIMPLE graphics with MINIMAL content.

MANDATORY prompt requirements for EVERY poster graphic:

POSTER FORMAT REQUIREMENTS (STRICTLY ENFORCE):
- ABSOLUTE MAXIMUM 3-4 elements per graphic (3 is ideal)
- ABSOLUTE MAXIMUM 10 words total in the entire graphic
- NO complex workflows with 5+ steps (split into 2-3 simple graphics instead)
- NO multi-level nested diagrams (flatten to single level)
- NO case studies with multiple sub-sections (one key point per case)
- ALL text GIANT BOLD (80pt+ for labels, 120pt+ for key numbers)
- High contrast ONLY (dark on white OR white on dark, NO gradients with text)
- MANDATORY 50% white space minimum (half the graphic should be empty)
- Thick lines only (5px+ minimum), large icons (200px+ minimum)
- ONE SINGLE MESSAGE per graphic (not 3 related messages)

⚠️ BEFORE GENERATING: Review your prompt and count elements

• If your description has 5+ items → STOP. Split into multiple graphics
• If your workflow has 5+ stages → STOP. Show only 3-4 high-level steps
• If your comparison has 4+ methods → STOP. Show only top 3 or Our vs Best Baseline

Content limits per graphic type (STRICT):

Example - WRONG (7-stage workflow - TOO COMPLEX):

# ❌ BAD - This creates tiny unreadable text like the drug discovery poster
python scripts/generate_schematic.py "Drug discovery workflow showing: Stage 1 Target Identification, Stage 2 Molecular Synthesis, Stage 3 Virtual Screening, Stage 4 AI Lead Optimization, Stage 5 Clinical Trial Design, Stage 6 FDA Approval. Include success metrics, timelines, and validation steps for each stage." -o figures/workflow.png
# Result: 7+ stages with tiny text, unreadable from 6 feet - POSTER FAILURE

Example - CORRECT (simplified to 3 key stages):

# ✅ GOOD - Same content, split into ONE simple high-level graphic
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word in GIANT bold (120pt+). Thick arrows (10px). 60% white space. NO substeps, NO details. 3 words total. Readable from 10 feet." -o figures/workflow_overview.png
# Result: Clean, impactful, readable - can add detail graphics separately if needed

Example - WRONG (complex case studies with multiple sections):

# ❌ BAD - Creates cramped unreadable sections
python scripts/generate_schematic.py "Case studies: Insilico Medicine (drug candidate, discovery time, clinical trials), Recursion Pharma (platform, methodology, results), Exscientia (drug candidates, FDA status, timeline). Include company logos, metrics, and outcomes." -o figures/cases.png
# Result: 3 case studies with 4+ elements each = 12+ total elements, tiny text

Example - CORRECT (one case study, one key metric):

# ✅ GOOD - Show ONE case with ONE key number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study card: Company logo (large), '18 MONTHS' in GIANT text (150pt), 'to discovery' below (60pt). 3 elements total: logo + number + caption. 50% white space. Readable from 10 feet." -o figures/case_single.png
# Result: Clear, readable, impactful. Make 3 separate graphics if you need 3 cases.

Example - WRONG (key findings too complex):

# BAD - too many items, too much detail
python scripts/generate_schematic.py "Key findings showing 8 metrics: accuracy 95%, precision 92%, recall 94%, F1 0.93, AUC 0.97, training time 2.3 hours, inference 50ms, model size 145MB with comparison to 5 baseline methods" -o figures/findings.png
# Result: Cramped graphic with tiny numbers

Example - CORRECT (key findings simple):

# GOOD - only 3 key items, giant numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with ONLY 3 large cards. Card 1: '95%' in GIANT text (120pt) with 'ACCURACY' below (48pt). Card 2: '2X' in GIANT text with 'FASTER' below. Card 3: checkmark icon with 'VALIDATED' in large text. 50% white space. High contrast colors. NO other text or details." -o figures/findings.png
# Result: Bold, readable impact statement

Font size reference for poster prompts:

Always include in prompts:

• "POSTER FORMAT" or "for A0 poster" or "readable from 6 feet"
• "VERY LARGE TEXT" or "huge bold fonts"
• Specific text that should appear (so it's baked into the image)
• "minimal text, maximum impact"
• "high contrast" for readability
• "generous margins" and "no text near edges"

---

CRITICAL: AI-Generated Graphic Sizing

⚠️ Each AI-generated graphic should focus on ONE concept with MINIMAL content.

Problem: Generating complex diagrams with many elements leads to small text.

Solution: Generate SIMPLE graphics with FEW elements and LARGE text.

Example - WRONG (too complex, text will be small):

# BAD - too many elements in one graphic
python scripts/generate_schematic.py "Complete ML pipeline showing data collection, 
preprocessing with 5 steps, feature engineering with 8 techniques, model training 
with hyperparameter tuning, validation with cross-validation, and deployment with 
monitoring. Include all labels and descriptions." -o figures/pipeline.png

Example - CORRECT (simple, focused, large text):

# GOOD - split into multiple simple graphics with large text

# Graphic 1: High-level overview (3-4 elements max)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Simple 4-step pipeline. 
Four large boxes: DATA → PROCESS → MODEL → RESULTS. 
GIANT labels (80pt+), thick arrows, lots of white space. 
Only 4 words total. Readable from 8 feet." -o figures/overview.png

# Graphic 2: Key result (1 metric highlighted)
python scripts/generate_schematic.py "POSTER FORMAT for A0: Single key metric display.
Giant '95%' text (150pt+) with 'ACCURACY' below (60pt+).
Checkmark icon. Minimal design, high contrast.
Readable from 10 feet." -o figures/accuracy.png

Rules for AI-generated poster graphics:

Split complex content into multiple simple graphics:

Instead of 1 complex diagram with 12 elements:
→ Create 3 simple diagrams with 4 elements each
→ Each graphic can have LARGER text
→ Arrange in poster with clear visual flow

---

Step 0: MANDATORY Pre-Generation Review (DO THIS FIRST)

⚠️ BEFORE generating ANY graphics, review your content plan:

For EACH planned graphic, ask these questions: 1. Element count: Can I describe this in 3-4 items or less?

• ❌ NO → Simplify or split into multiple graphics
• ✅ YES → Continue

2. Complexity check: Is this a multi-stage workflow (5+ steps) or nested diagram?

• ❌ YES → Flatten to 3-4 high-level steps only
• ✅ NO → Continue

3. Word count: Can I describe all text in 10 words or less?

• ❌ NO → Cut text, use single-word labels
• ✅ YES → Continue

4. Message clarity: Does this graphic convey ONE clear message?

• ❌ NO → Split into multiple focused graphics
• ✅ YES → Continue to generation

Common patterns that ALWAYS fail (reject these):

• "Show stages 1 through 7..." → Split into high-level overview (3 stages) + detail graphics
• "Multiple case studies..." → One case per graphic
• "Timeline from 2015 to 2024 with annual milestones..." → Show only 3-4 key years
• "Comparison of 6 methods..." → Show only top 3 or Our method vs Best baseline
• "Architecture with all layers and connections..." → High-level only (3-4 components)

Step 1: Plan Your Poster Elements

After passing the pre-generation review, identify visual elements needed:

1. Title Block - Stylized title with institutional branding (optional - can be LaTeX text) 2. Introduction Graphic - Conceptual overview (3 elements max) 3. Methods Diagram - High-level workflow (3-4 steps max) 4. Results Figures - Key findings (3 metrics max per figure, may need 2-3 separate figures) 5. Conclusion Graphic - Summary visual (3 takeaways max) 6. Supplementary Icons - Simple icons, QR codes, logos (minimal)

Step 2: Generate Each Element (After Pre-Generation Review)

⚠️ CRITICAL: Review Step 0 checklist before proceeding.

Use the appropriate tool for each element type:

For Schematics and Diagrams (scientific-schematics):

# Create figures directory
mkdir -p figures

# Drug discovery workflow - HIGH-LEVEL ONLY, 3 stages
# BAD: "Stage 1: Target ID, Stage 2: Molecular Synthesis, Stage 3: Virtual Screening, Stage 4: AI Lead Opt..."
# GOOD: Collapse to 3 mega-stages
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' (120pt bold) → 'VALIDATE' (120pt bold) → 'APPROVE' (120pt bold). Thick arrows (10px). 60% white space. ONLY these 3 words. NO substeps. Readable from 12 feet." -o figures/workflow_simple.png

# System architecture - MAXIMUM 3 components
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-component stack: 'DATA' box (120pt) → 'AI MODEL' box (120pt) → 'PREDICTION' box (120pt). Thick vertical arrows. 60% white space. 3 words only. Readable from 12 feet." -o figures/architecture.png

# Timeline - ONLY 3 key milestones (not year-by-year)
# BAD: "2018, 2019, 2020, 2021, 2022, 2023, 2024 with events"
# GOOD: Only 3 breakthrough moments
python scripts/generate_schematic.py "POSTER FORMAT for A0. Timeline with ONLY 3 points: '2018' + icon, '2021' + icon, '2024' + icon. GIANT years (120pt). Large icons. 60% white space. NO connecting lines or details. Readable from 12 feet." -o figures/timeline.png

# Case study - ONE case, ONE key metric
# BAD: "3 case studies: Insilico (details), Recursion (details), Exscientia (details)"
# GOOD: ONE case with ONE number
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case study: Large logo + '18 MONTHS' (150pt bold) + 'to discovery' (60pt). 3 elements total. 60% white space. Readable from 12 feet." -o figures/case1.png

# If you need 3 cases → make 3 separate simple graphics (not one complex graphic)

For Stylized Blocks and Graphics (Nano Banana Pro):

# Title block - SIMPLE
python scripts/generate_schematic.py "POSTER FORMAT for A0. Title block: 'ML FOR DRUG DISCOVERY' in HUGE bold text (120pt+). Dark blue background. ONE subtle icon. NO other text. 40% white space. Readable from 15 feet." -o figures/title_block.png

# Introduction visual - SIMPLE, 3 elements only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE problem visual with ONLY 3 icons: drug icon, arrow, target icon. ONE label per icon (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/intro_visual.png

# Conclusion/summary - ONLY 3 items, GIANT numbers
python scripts/generate_schematic.py "POSTER FORMAT for A0. KEY FINDINGS with EXACTLY 3 cards only. Card 1: '95%' (150pt font) with 'ACCURACY' (60pt). Card 2: '2X' (150pt) with 'FASTER' (60pt). Card 3: checkmark icon with 'READY' (60pt). 50% white space. NO other text. Readable from 10 feet." -o figures/conclusions_graphic.png

# Background visual - SIMPLE, 3 icons only
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 large icons in a row: problem icon → challenge icon → impact icon. ONE word label each (80pt+). 50% white space. NO detailed text. Readable from 8 feet." -o figures/background_visual.png

For Data Visualizations - SIMPLE, 3 bars max:

# SIMPLE chart with ONLY 3 bars, GIANT labels
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: BASELINE (70%), EXISTING (85%), OURS (95%). GIANT percentage labels ON the bars (100pt+). NO axis labels, NO legend, NO gridlines. Our bar highlighted in different color. 40% white space. Readable from 8 feet." -o figures/comparison_chart.png

Step 2b: MANDATORY Post-Generation Review (Before Assembly)

⚠️ CRITICAL: Review EVERY generated graphic before adding to poster.

For each generated figure, open at 25% zoom and check:

1. ✅ PASS criteria (all must be true):

• Can read ALL text clearly at 25% zoom
• Count elements: 3-4 or fewer
• White space: 50%+ of image is empty
• Simple enough to understand in 2 seconds
• NOT a complex workflow with 5+ stages
• NOT multiple nested sections

2. ❌ FAIL criteria (regenerate if ANY are true):

• Text is small or hard to read at 25% zoom → REGENERATE with "150pt+" fonts
• More than 4 elements → REGENERATE with "ONLY 3 elements"
• Less than 50% white space → REGENERATE with "60% white space"
• Complex multi-stage workflow → SPLIT into 2-3 simple graphics
• Multiple case studies cramped together → SPLIT into separate graphics
• Takes more than 3 seconds to understand → SIMPLIFY and regenerate

Common failures and fixes:

• "7-stage workflow with tiny text" → Regenerate as "3 high-level stages only"
• "3 case studies in one graphic" → Generate 3 separate simple graphics
• "Timeline with 8 years" → Regenerate with "ONLY 3 key milestones"
• "Comparison of 5 methods" → Regenerate with "ONLY Our method vs Best baseline (2 bars)"

DO NOT PROCEED to assembly if ANY graphic fails the checks above.

Step 3: Assemble in LaTeX Template

After all figures pass the post-generation review, include them in your poster template:

tikzposter example:

\documentclass[25pt, a0paper, portrait]{tikzposter}

\begin{document}

\maketitle

\begin{columns}
\column{0.5}

\block{Introduction}{
  \centering
  \includegraphics[width=0.85\linewidth]{figures/intro_visual.png}
  
  \vspace{0.5em}
  Brief context text here (2-3 sentences max).
}

\block{Methods}{
  \centering
  \includegraphics[width=0.9\linewidth]{figures/methods_flowchart.png}
}

\column{0.5}

\block{Results}{
  \begin{minipage}{0.48\linewidth}
    \centering
    \includegraphics[width=\linewidth]{figures/result_1.png}
  \end{minipage}
  \hfill
  \begin{minipage}{0.48\linewidth}
    \centering
    \includegraphics[width=\linewidth]{figures/result_2.png}
  \end{minipage}
  
  \vspace{0.5em}
  Key findings in 3-4 bullet points.
}

\block{Conclusions}{
  \centering
  \includegraphics[width=0.8\linewidth]{figures/conclusions_graphic.png}
}

\end{columns}

\end{document}

baposter example:

\headerbox{Methods}{name=methods,column=0,row=0}{
  \centering
  \includegraphics[width=0.95\linewidth]{figures/methods_flowchart.png}
}

\headerbox{Results}{name=results,column=1,row=0}{
  \includegraphics[width=\linewidth]{figures/comparison_chart.png}
  \vspace{0.3em}
  
  Key finding: Our method achieves 92% accuracy.
}

Example: Complete Poster Generation Workflow

Full workflow with ALL quality checks:

# STEP 0: Pre-Generation Review (MANDATORY)
# Content plan: Drug discovery poster
# - Workflow: 7 stages → ❌ TOO MANY → Reduce to 3 mega-stages ✅
# - 3 case studies → ❌ TOO MANY → One case per graphic (make 3 graphics) ✅
# - Timeline 2018-2024 → ❌ TOO DETAILED → Only 3 key years ✅

# STEP 1: Create figures directory
mkdir -p figures

# STEP 2: Generate ULTRA-SIMPLE graphics with strict limits

# Workflow - HIGH-LEVEL ONLY (collapsed from 7 stages to 3)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word 120pt+ bold. Thick arrows (10px). 60% white space. ONLY 3 words total. Readable from 12 feet." -o figures/workflow.png

# Case study 1 - ONE case, ONE metric (will make 3 separate graphics)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '18 MONTHS' (150pt bold) + 'to drug discovery' (60pt). 3 elements only. 60% white space. Readable from 12 feet." -o figures/case1.png

python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + '95% SUCCESS' (150pt bold) + 'in trials' (60pt). 3 elements only. 60% white space." -o figures/case2.png

python scripts/generate_schematic.py "POSTER FORMAT for A0. ONE case: Company logo + 'FDA APPROVED' (150pt bold) + '2024' (60pt). 3 elements only. 60% white space." -o figures/case3.png

# Timeline - ONLY 3 key years (not 7 years)
python scripts/generate_schematic.py "POSTER FORMAT for A0. ONLY 3 years: '2018' (150pt) + icon, '2021' (150pt) + icon, '2024' (150pt) + icon. Large icons. 60% white space. NO lines or details. Readable from 12 feet." -o figures/timeline.png

# Results - ONLY 2 bars (our method vs best baseline, not 5 methods)
python scripts/generate_schematic.py "POSTER FORMAT for A0. TWO bars only: 'BASELINE 70%' and 'OURS 95%' (highlighted). GIANT percentages (150pt) ON bars. NO axis, NO legend. 60% white space. Readable from 12 feet." -o figures/results.png

# STEP 2b: Post-Generation Review (MANDATORY)
# Open each figure at 25% zoom:
# ✅ workflow.png: 3 elements, text readable, 60% white - PASS
# ✅ case1.png: 3 elements, giant numbers, clean - PASS
# ✅ case2.png: 3 elements, giant numbers, clean - PASS  
# ✅ case3.png: 3 elements, giant numbers, clean - PASS
# ✅ timeline.png: 3 elements, readable, simple - PASS
# ✅ results.png: 2 bars, giant percentages, clear - PASS
# ALL PASS → Proceed to assembly

# STEP 3: Compile LaTeX poster
pdflatex poster.tex

# STEP 4: PDF Overflow Check (see Section 11)
grep "Overfull" poster.log
# Open at 100% and check all 4 edges

If ANY graphic fails Step 2b review:

• Too many elements → Regenerate with "ONLY 3 elements"
• Small text → Regenerate with "150pt+" or "GIANT BOLD (150pt+)"
• Cluttered → Regenerate with "60% white space" and "ULTRA-SIMPLE"
• Complex workflow → SPLIT into multiple simple 3-element graphics

Visual Element Guidelines

⚠️ CRITICAL: Each graphic must have ONE message and MAXIMUM 3-4 elements.

ABSOLUTE LIMITS - These are NOT guidelines, these are HARD LIMITS:

• MAXIMUM 3-4 elements per graphic (3 is ideal)
• MAXIMUM 10 words total per graphic
• MINIMUM 50% white space (60% is better)
• MINIMUM 120pt for key numbers/metrics
• MINIMUM 80pt for labels

For each poster section - STRICT requirements:

MANDATORY prompt elements (ALL required, NO exceptions): 1. "POSTER FORMAT for A0" - MUST be first 2. "ULTRA-SIMPLE" or "ONLY X elements" - content limit 3. "GIANT (120pt+)" or specific font sizes - readability 4. "60% white space" - mandatory breathing room 5. "readable from 10-12 feet" - viewing distance 6. Exact count of words/elements - "3 words total" or "ONLY 3 icons"

PATTERNS THAT ALWAYS FAIL (REJECT IMMEDIATELY):

• ❌ "7-stage drug discovery workflow" → Split to "3 mega-stages"
• ❌ "Timeline from 2015-2024 with annual updates" → "ONLY 3 key years"
• ❌ "3 case studies with details" → Make 3 separate simple graphics
• ❌ "Comparison of 5 methods with metrics" → "ONLY 2: ours vs best"
• ❌ "Complete architecture showing all layers" → "3 components only"
• ❌ "Show stages 1,2,3,4,5,6" → "3 high-level stages"

PATTERNS THAT WORK:

• ✅ "3 mega-stages collapsed from 7" → Proper simplification
• ✅ "ONE case with ONE metric" → Will make multiple if needed
• ✅ "ONLY 3 milestones" → Selective, focused
• ✅ "2 bars: ours vs baseline" → Direct comparison
• ✅ "3-component high-level view" → Appropriately simplified

Ensuring Full Page Coverage:

Posters should use the entire page without excessive margins. Configure packages correctly:

beamerposter - Full Page Setup:

\documentclass[final,t]{beamer}
\usepackage[size=a0,scale=1.4,orientation=portrait]{beamerposter}

% Remove default beamer margins
\setbeamersize{text margin left=0mm, text margin right=0mm}

% Use geometry for precise control
\usepackage[margin=10mm]{geometry}  % 10mm margins all around

% Remove navigation symbols
\setbeamertemplate{navigation symbols}{}

% Remove footline and headline if not needed
\setbeamertemplate{footline}{}
\setbeamertemplate{headline}{}

tikzposter - Full Page Setup:

\documentclass[
  25pt,                      % Font scaling
  a0paper,                   % Paper size
  portrait,                  % Orientation
  margin=10mm,               % Outer margins (minimal)
  innermargin=15mm,          % Space inside blocks
  blockverticalspace=15mm,   % Space between blocks
  colspace=15mm,             % Space between columns
  subcolspace=8mm            % Space between subcolumns
]{tikzposter}

% This ensures content fills the page

baposter - Full Page Setup:

\documentclass[a0paper,portrait,fontscale=0.285]{baposter}

\begin{poster}{
  grid=false,
  columns=3,
  colspacing=1.5em,          % Space between columns
  eyecatcher=true,
  background=plain,
  bgColorOne=white,
  borderColor=blue!50,
  headerheight=0.12\textheight,  % 12% for header
  textborder=roundedleft,
  headerborder=closed,
  boxheaderheight=2em        % Consistent box header heights
}
% Content here
\end{poster}

Common Issues and Fixes:

Problem: Large white margins around poster

% Fix for beamerposter
\setbeamersize{text margin left=5mm, text margin right=5mm}

% Fix for tikzposter
\documentclass[..., margin=5mm, innermargin=10mm]{tikzposter}

% Fix for baposter - adjust in document class
\documentclass[a0paper, margin=5mm]{baposter}

Problem: Content doesn't fill vertical space

% Use \vfill between sections to distribute space
\block{Introduction}{...}
\vfill
\block{Methods}{...}
\vfill
\block{Results}{...}

% Or manually adjust block spacing
\vspace{1cm}  % Add space between specific blocks

Problem: Poster extends beyond page boundaries

% Check total width calculation
% For 3 columns with spacing:
% Total = 3×columnwidth + 2×colspace + 2×margins
% Ensure this equals \paperwidth

% Debug by adding visible page boundary
\usepackage{eso-pic}
\AddToShipoutPictureBG{
  \AtPageLowerLeft{
    \put(0,0){\framebox(\LenToUnit{\paperwidth},\LenToUnit{\paperheight}){}}
  }
}

Print Preparation:

• Generate PDF/X-1a for professional printing
• Embed all fonts
• Convert colors to CMYK if required
• Check resolution of all images (minimum 300 DPI)
• Add bleed area if required by printer (usually 3-5mm)
• Verify page size matches requirements exactly

Digital Display:

• RGB color space for screen display
• Optimize file size for email/web
• Test readability on different screens

11. PDF Review and Quality Control

CRITICAL: Always review the generated PDF before printing or presenting. Use this systematic checklist:

Step 1: Page Size Verification

# Check PDF dimensions (should match poster size exactly)
pdfinfo poster.pdf | grep "Page size"

# Expected outputs:
# A0: 2384 x 3370 points (841 x 1189 mm)
# 36x48": 2592 x 3456 points
# A1: 1684 x 2384 points (594 x 841 mm)

Step 2: OVERFLOW CHECK (CRITICAL) - DO THIS IMMEDIATELY AFTER COMPILATION

⚠️ THIS IS THE #1 CAUSE OF POSTER FAILURES. Check BEFORE proceeding.

Step 2a: Check LaTeX Log File

# Check for overflow warnings (these are ERRORS, not suggestions)
grep -i "overfull\|underfull\|badbox" poster.log

# ANY "Overfull" warning = content is cut off or extending beyond boundaries
# FIX ALL OF THESE before proceeding

Common overflow warnings and what they mean:

• Overfull \hbox (15.2pt too wide) → Text or graphic is 15.2pt wider than column
• Overfull \vbox (23.5pt too high) → Content is 23.5pt taller than available space
• Badbox → LaTeX struggling to fit content within boundaries

Step 2b: Visual Edge Inspection (100% zoom in PDF viewer)

Check ALL FOUR EDGES systematically:

1. TOP EDGE:

• [ ] Title completely visible (not cut off)
• [ ] Author names fully visible
• [ ] No graphics touching top margin
• [ ] Header content within safe zone

2. BOTTOM EDGE:

• [ ] References fully visible (not cut off)
• [ ] Acknowledgments complete
• [ ] Contact info readable
• [ ] No graphics cut off at bottom

3. LEFT EDGE:

• [ ] No text touching left margin
• [ ] All bullet points fully visible
• [ ] Graphics have left margin (not bleeding off)
• [ ] Column content within bounds

4. RIGHT EDGE:

• [ ] No text extending beyond right margin
• [ ] Graphics not cut off on right
• [ ] Column content stays within bounds
• [ ] QR codes fully visible

5. BETWEEN COLUMNS:

• [ ] Content stays within individual columns
• [ ] No text bleeding into adjacent columns
• [ ] Figures respect column boundaries

If ANY check fails, you have overflow. FIX IMMEDIATELY before continuing:

Fix hierarchy (try in order): 1. Check AI-generated graphics first:

• Are they too complex (5+ elements)? → Regenerate simpler
• Do they have tiny text? → Regenerate with "150pt+" fonts
• Are there too many? → Reduce number of figures

2. Reduce sections:

• More than 5-6 sections? → Combine or remove
• Example: Merge "Discussion" into "Conclusions"

3. Cut text content:

• More than 800 words total? → Cut to 300-500
• More than 100 words per section? → Cut to 50-80

4. Adjust figure sizing:

• Using width=\linewidth? → Change to width=0.85\linewidth
• Using width=1.0\columnwidth? → Change to width=0.9\columnwidth

5. Increase margins (last resort):

   \documentclass[25pt, a0paper, portrait, margin=25mm]{tikzposter}

DO NOT proceed to Step 3 if ANY overflow exists.

Step 3: Visual Inspection Checklist

Open PDF at 100% zoom and check:

Layout and Spacing:

• [ ] Content fills entire page (no large white margins)
• [ ] Consistent spacing between columns
• [ ] Consistent spacing between blocks/sections
• [ ] All elements aligned properly (use ruler tool)
• [ ] No overlapping text or figures
• [ ] White space evenly distributed

Typography:

• [ ] Title clearly visible and large (72pt+)
• [ ] Section headers readable (48-72pt)
• [ ] Body text readable at 100% zoom (24-36pt minimum)
• [ ] No text cutoff or running off edges
• [ ] Consistent font usage throughout
• [ ] All special characters render correctly (symbols, Greek letters)

Visual Elements:

• [ ] All figures display correctly
• [ ] No pixelated or blurry images
• [ ] Figure captions present and readable
• [ ] Colors render as expected (not washed out or too dark)
• [ ] Logos display clearly
• [ ] QR codes visible and scannable

Content Completeness:

• [ ] Title and authors complete
• [ ] All sections present (Intro, Methods, Results, Conclusions)
• [ ] References included
• [ ] Contact information visible
• [ ] Acknowledgments (if applicable)
• [ ] No placeholder text remaining (Lorem ipsum, TODO, etc.)

Technical Quality:

• [ ] No LaTeX compilation warnings in important areas
• [ ] All citations resolved (no [?] marks)
• [ ] All cross-references working
• [ ] Page boundaries correct (no content cut off)

Step 4: Reduced-Scale Print Test

Essential Pre-Printing Test:

# Create reduced-size test print (25% of final size)
# This simulates viewing full poster from ~8-10 feet

# For A0 poster, print on A4 paper (24.7% scale)
# For 36x48" poster, print on letter paper (~25% scale)

Print Test Checklist:

• [ ] Title readable from 6 feet away
• [ ] Section headers readable from 4 feet away
• [ ] Body text readable from 2 feet away
• [ ] Figures clear and understandable
• [ ] Colors printed accurately
• [ ] No obvious design flaws

Step 5: Digital Quality Checks

Font Embedding Verification:

# Check that all fonts are embedded (required for printing)
pdffonts poster.pdf

# All fonts should show "yes" in "emb" column
# If any show "no", recompile with:
pdflatex -dEmbedAllFonts=true poster.tex

Image Resolution Check:

# Extract image information
pdfimages -list poster.pdf

# Check that all images are at least 300 DPI
# Formula: DPI = pixels / (inches in poster)
# For A0 width (33.1"): 300 DPI = 9930 pixels minimum

File Size Optimization:

# For email/web, compress if needed (>50MB)
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
   -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH \
   -sOutputFile=poster_compressed.pdf poster.pdf

# For printing, keep original (no compression)

Step 6: Accessibility Check

Color Contrast Verification:

• [ ] Text-background contrast ratio ≥ 4.5:1 (WCAG AA)
• [ ] Important elements contrast ratio ≥ 7:1 (WCAG AAA)
• Test online: https://webaim.org/resources/contrastchecker/

Color Blindness Simulation:

• [ ] View PDF through color blindness simulator
• [ ] Information not lost with red-green simulation
• [ ] Use Coblis (color-blindness.com) or similar tool

Step 7: Content Proofreading

Systematic Review:

• [ ] Spell-check all text
• [ ] Verify all author names and affiliations
• [ ] Check all numbers and statistics for accuracy
• [ ] Confirm all citations are correct
• [ ] Review figure labels and captions
• [ ] Check for typos in headers and titles

Peer Review:

• [ ] Ask colleague to review poster
• [ ] 30-second test: Can they identify main message?
• [ ] 5-minute review: Do they understand conclusions?
• [ ] Note any confusing elements

Step 8: Technical Validation

LaTeX Compilation Log Review:

# Check for warnings in .log file
grep -i "warning\|error\|overfull\|underfull" poster.log

# Common issues to fix:
# - Overfull hbox: Text extending beyond margins
# - Underfull hbox: Excessive spacing
# - Missing references: Citations not resolved
# - Missing figures: Image files not found

Fix Common Warnings:

% Overfull hbox (text too wide)
\usepackage{microtype}  % Better spacing
\sloppy  % Allow slightly looser spacing
\hyphenation{long-word}  % Manual hyphenation

% Missing fonts
\usepackage[T1]{fontenc}  % Better font encoding

% Image not found
% Ensure paths are correct and files exist
\graphicspath{{./figures/}{./images/}}

Step 9: Final Pre-Print Checklist

Common PDF Issues and Solutions:

11. Common Poster Content Patterns

Effective content organization for different research types:

Experimental Research Poster: 1. Title and authors 2. Introduction: Problem and hypothesis 3. Methods: Experimental design (with diagram) 4. Results: Key findings (2-4 main figures) 5. Conclusions: Main takeaways (3-5 bullet points) 6. Future work (optional) 7. References and acknowledgments

Computational/Modeling Poster: 1. Title and authors 2. Motivation: Problem statement 3. Approach: Algorithm or model (with flowchart) 4. Implementation: Technical details 5. Results: Performance metrics and comparisons 6. Applications: Use cases 7. Code availability (QR code to GitHub) 8. References

Review/Survey Poster: 1. Title and authors 2. Scope: Topic overview 3. Methods: Literature search strategy 4. Key findings: Main themes (organized by category) 5. Trends: Visualizations of publication patterns 6. Gaps: Identified research needs 7. Conclusions: Summary and implications 8. References

12. Accessibility and Inclusive Design

Design posters that are accessible to diverse audiences:

Color Blindness Considerations:

• Avoid red-green combinations (most common color blindness)
• Use patterns or shapes in addition to color
• Test with color-blindness simulators
• Provide high contrast (WCAG AA standard: 4.5:1 minimum)

Visual Impairment Accommodations:

• Large, clear fonts (minimum 24pt body text)
• High contrast text and background
• Clear visual hierarchy
• Avoid complex textures or patterns in backgrounds

Language and Content:

• Clear, concise language
• Define acronyms and jargon
• International audience considerations
• Consider multilingual QR code options for global conferences

13. Poster Presentation Best Practices

Guidance beyond LaTeX for effective poster sessions:

Content Strategy:

• Tell a story, don't just list facts
• Focus on 1-3 main messages
• Use visual abstract or graphical summary
• Leave room for conversation (don't over-explain)

Physical Presentation Tips:

• Bring printed handouts or business cards with QR code
• Prepare 30-second, 2-minute, and 5-minute verbal summaries
• Stand to the side, not blocking the poster
• Engage viewers with open-ended questions

Digital Backups:

• Save poster as PDF on mobile device
• Prepare digital version for email sharing
• Create social media-friendly image version
• Have backup printed copy or digital display option

Workflow for Poster Creation

Stage 1: Planning and Content Development

1. Determine poster requirements:

• Conference size specifications (A0, 36×48", etc.)
• Orientation (portrait vs. landscape)
• Submission deadlines and format requirements

2. Develop content outline:

• Identify 1-3 core messages
• Select key figures (typically 3-6 main visuals)
• Draft concise text for each section (bullet points preferred)
• Aim for 300-800 words total

3. Choose LaTeX package:

• beamerposter: If familiar with Beamer, need institutional themes
• tikzposter: For modern, colorful designs with flexibility
• baposter: For structured, professional multi-column layouts

Stage 2: Generate Visual Elements (AI-Powered)

CRITICAL: Generate SIMPLE figures with MINIMAL content. Each graphic = ONE message.

Content limits:

• Maximum 4-5 elements per graphic
• Maximum 15 words total per graphic
• 50% white space minimum
• GIANT fonts (80pt+ for labels, 120pt+ for key numbers)

1. Create figures directory:

   mkdir -p figures

2. Generate SIMPLE visual elements:

   # Introduction - ONLY 3 icons/elements
   python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 elements: [icon1] [icon2] [icon3]. ONE word labels (80pt+). 50% white space. Readable from 8 feet." -o figures/intro.png
   
   # Methods - ONLY 4 steps maximum
   python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: STEP1 → STEP2 → STEP3 → STEP4. GIANT labels (100pt+). 50% white space. NO sub-steps." -o figures/methods.png
   
   # Results - ONLY 3 bars/comparisons
   python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE chart with ONLY 3 bars. GIANT percentages ON bars (120pt+). NO axis, NO legend. 50% white space." -o figures/results.png
   
   # Conclusions - EXACTLY 3 items with GIANT numbers
   python scripts/generate_schematic.py "POSTER FORMAT for A0. EXACTLY 3 key findings: '[NUMBER]' (150pt) '[LABEL]' (60pt) for each. 50% white space. NO other text." -o figures/conclusions.png

3. Review generated figures - check for overflow:

• View at 25% zoom: All text still readable?
• Count elements: More than 5? → Regenerate simpler
• Check white space: Less than 40%? → Add "60% white space" to prompt
• Font too small?: Add "EVEN LARGER" or increase pt sizes
• Still overflowing?: Reduce to 3 elements instead of 4-5

Stage 3: Design and Layout

1. Select or create template:

• Start with provided templates in assets/
• Customize color scheme to match branding
• Configure page size and orientation

2. Design layout structure:

• Plan column structure (2, 3, or 4 columns)
• Map content flow (typically left-to-right, top-to-bottom)
• Allocate space for title (10-15%), content (70-80%), footer (5-10%)

3. Set typography:

• Configure font sizes for different hierarchy levels
• Ensure minimum 24pt body text
• Test readability from 4-6 feet distance

Stage 4: Content Integration

1. Create poster header:

• Title (concise, descriptive, 10-15 words)
• Authors and affiliations
• Institution logos (high-resolution)
• Conference logo if required

2. Integrate AI-generated figures:

• Add all figures from Stage 2 to appropriate sections
• Use \includegraphics with proper sizing
• Ensure figures dominate each section (visuals first, text second)
• Center figures within blocks for visual impact

3. Add minimal supporting text:

• Keep text minimal and scannable (300-800 words total)
• Use bullet points, not paragraphs
• Write in active voice
• Text should complement figures, not duplicate them

4. Add supplementary elements:

• QR codes for supplementary materials
• References (cite key papers only, 5-10 typical)
• Contact information and acknowledgments

Stage 5: Refinement and Testing

1. Review and iterate:

• Check for typos and errors
• Verify all figures are high resolution
• Ensure consistent formatting
• Confirm color scheme works well together

2. Test readability:

• Print at 25% scale and read from 2-3 feet (simulates poster from 8-12 feet)
• Check color on different monitors
• Verify QR codes function correctly
• Ask colleague to review

3. Optimize for printing:

• Embed all fonts in PDF
• Verify image resolution
• Check PDF size requirements
• Include bleed area if required

Stage 6: Compilation and Delivery

1. Compile final PDF:

   pdflatex poster.tex
   # Or for better font support:
   lualatex poster.tex

2. Verify output quality:

• Check all elements are visible and correctly positioned
• Zoom to 100% and inspect figure quality
• Verify colors match expectations
• Confirm PDF opens correctly on different viewers

3. Prepare for printing:

• Export as PDF/X-1a if required
• Save backup copies
• Get test print on regular paper first
• Order professional printing 2-3 days before deadline

4. Create supplementary materials:

• Save PNG/JPG version for social media
• Create handout version (8.5×11" summary)
• Prepare digital version for email sharing

Integration with Other Skills

This skill works effectively with:

• Scientific Schematics: CRITICAL - Use for generating all poster diagrams and flowcharts
• Generate Image / Nano Banana Pro: For stylized graphics, conceptual illustrations, and summary visuals
• Scientific Writing: For developing poster content from papers
• Literature Review: For contextualizing research
• Data Analysis: For creating result figures and charts

Recommended workflow: Always use scientific-schematics and generate-image skills BEFORE creating the LaTeX poster to generate all visual elements.

Common Pitfalls to Avoid

AI-Generated Graphics Mistakes (MOST COMMON):

• ❌ Too many elements in one graphic (10+ items) → Keep to 3-5 max
• ❌ Text too small in AI graphics → Specify "GIANT (100pt+)" or "HUGE (150pt+)"
• ❌ Too much detail in prompts → Use "SIMPLE" and "ONLY X elements"
• ❌ No white space specification → Add "50% white space" to every prompt
• ❌ Complex flowcharts with 8+ steps → Limit to 4-5 steps maximum
• ❌ Comparison charts with 6+ items → Limit to 3 items maximum
• ❌ Key findings with 5+ metrics → Show only top 3

Fixing Overflow in AI Graphics: If your AI-generated graphics are overflowing or have small text: 1. Add "SIMPLER" or "ONLY 3 elements" to prompt 2. Increase font sizes: "150pt+" instead of "80pt+" 3. Add "60% white space" instead of "50%" 4. Remove sub-details: "NO sub-steps", "NO axis labels", "NO legend" 5. Regenerate with fewer elements

Design Mistakes:

• ❌ Too much text (over 1000 words)
• ❌ Font sizes too small (under 24pt body text)
• ❌ Low-contrast color combinations
• ❌ Cluttered layout with no white space
• ❌ Inconsistent styling across sections
• ❌ Poor quality or pixelated images

Content Mistakes:

• ❌ No clear narrative or message
• ❌ Too many research questions or objectives
• ❌ Overuse of jargon without definitions
• ❌ Results without context or interpretation
• ❌ Missing author contact information

Technical Mistakes:

• ❌ Wrong poster dimensions for conference requirements
• ❌ RGB colors sent to CMYK printer (color shift)
• ❌ Fonts not embedded in PDF
• ❌ File size too large for submission portal
• ❌ QR codes too small or not tested

Best Practices:

• ✅ Generate SIMPLE AI graphics with 3-5 elements max
• ✅ Use GIANT fonts (100pt+) for key numbers in graphics
• ✅ Specify "50% white space" in every AI prompt
• ✅ Follow conference size specifications exactly
• ✅ Test print at reduced scale before final printing
• ✅ Use high-contrast, accessible color schemes
• ✅ Keep text minimal and highly scannable
• ✅ Include clear contact information and QR codes
• ✅ Proofread carefully (errors are magnified on posters!)

• Typography: 72pt+ title, 48-72pt headers, 24-36pt body text
• Color: High contrast (≥4.5:1), color-blind friendly palettes
• Layout: Clear visual hierarchy, logical flow
• Content: 300-800 words maximum, 40-50% visual content

Common Poster Sizes

Templates support all standard sizes:

Workflow

Recommended Poster Creation Process

1. Planning (before LaTeX)

• Determine conference requirements (size, orientation)
• Identify 3-5 key results to highlight
• Create figures (300+ DPI)
• Draft 300-800 word content outline

2. Template Selection

• Choose package based on needs:
• beamerposter: Traditional conferences, institutional branding
• tikzposter: Modern conferences, creative fields
• baposter: Multi-section posters, structured layouts

3. Content Integration

• Copy template and customize
• Replace placeholder text
• Add figures and ensure high resolution
• Configure colors to match branding

4. Compilation & Review

• Compile to PDF
• Run review_poster.sh for automated checks
• Review visually at 100% zoom
• Check against poster_quality_checklist.md

5. Test Print

• Critical step! Print at 25% scale
• A0 → A4 paper, 36×48" → Letter paper
• View from 2-3 feet (simulates 8-12 feet for full poster)
• Verify readability and colors

6. Revisions

• Fix any issues identified
• Proofread carefully (errors are magnified!)
• Get colleague feedback
• Final compilation

7. Printing

• Verify page size: pdfinfo poster.pdf
• Check fonts embedded: pdffonts poster.pdf
• Send to professional printer 2-3 days before deadline
• Keep backup copy

Troubleshooting

Large White Margins

Problem: Excessive white space around poster edges

Solution:

% beamerposter
\setbeamersize{text margin left=5mm, text margin right=5mm}
\usepackage[margin=10mm]{geometry}

% tikzposter
\documentclass[..., margin=5mm, innermargin=10mm]{tikzposter}

% baposter
\documentclass[a0paper, margin=5mm]{baposter}

Content Cut Off

Problem: Text or figures extending beyond page

Solution:

• Check total width: columns + spacing + margins = pagewidth
• Reduce column widths or spacing
• Debug with visible page boundary:

\usepackage{eso-pic}
\AddToShipoutPictureBG{
  \AtPageLowerLeft{
    \put(0,0){\framebox(\LenToUnit{\paperwidth},\LenToUnit{\paperheight}){}}
  }
}

Blurry Images

Problem: Pixelated or low-quality figures

Solution:

• Use vector graphics (PDF, SVG) when possible
• Raster images: minimum 300 DPI at final print size
• For A0 width (33.1"): 300 DPI = 9930 pixels minimum
• Check with: pdfimages -list poster.pdf

Fonts Not Embedded

Problem: Printer rejects PDF due to missing fonts

Solution:

# Recompile with embedded fonts
pdflatex -dEmbedAllFonts=true poster.tex

# Verify embedding
pdffonts poster.pdf
# All fonts should show "yes" in "emb" column

File Too Large

Problem: PDF exceeds email size limit (>50MB)

Solution:

# Compress for digital sharing
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 \
   -dPDFSETTINGS=/printer -dNOPAUSE -dQUIET -dBATCH \
   -sOutputFile=poster_compressed.pdf poster.pdf

# Keep original uncompressed version for printing

Common Mistakes to Avoid

Content

• ❌ Too much text (>1000 words)
• ❌ Font sizes too small (<24pt body text)
• ❌ No clear main message
• ✅ 300-800 words, 30pt+ body text, 1-3 key findings

Design

• ❌ Poor color contrast (<4.5:1)
• ❌ Red-green color combinations (color-blind issue)
• ❌ Cluttered layout with no white space
• ✅ High contrast, accessible colors, generous spacing

Technical

• ❌ Wrong poster dimensions
• ❌ Low resolution images (<300 DPI)
• ❌ Fonts not embedded
• ✅ Verify specs, high-res images, embedded fonts

Tips for Success

Content Strategy

1. One main message: What's the one thing viewers should remember? 2. 3-5 key figures: Visual content dominates 3. 300-800 words: Less is more 4. Bullet points: More scannable than paragraphs

Design Strategy

1. High contrast: Dark on light or light on dark 2. Large fonts: 30pt+ body text for readability from distance 3. White space: 30-40% of poster should be empty 4. Visual hierarchy: Vary sizes significantly (title 3× body text)

Technical Strategy

1. Test early: Print at 25% scale before final printing 2. Vector graphics: Use PDF/SVG when possible 3. Verify specs: Check page size, fonts, resolution 4. Get feedback: Ask colleague to review before printing
