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:
Plan all visual elements needed (title, intro, methods, results, conclusions)
Generate each element using scientific-schematics or Nano Banana Pro
Assemble generated images in the LaTeX template
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:
Title/footer text extending beyond page boundaries
Too many sections crammed into available space
Figures placed too close to edges
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
# ❌ 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:
Element
Minimum Size
Prompt Keywords
Main numbers/metrics
72pt+
"huge", "very large", "giant", "poster-size"
Section titles
60pt+
"large bold", "prominent"
Labels/captions
36pt+
"readable from 6 feet", "clear labels"
Body text
24pt+
"poster-readable", "large text"
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:
Rule
Limit
Reason
Elements per graphic
3-5 maximum
More elements = smaller text
Words per graphic
10-15 maximum
Minimal text = larger fonts
Flowchart steps
4-5 maximum
Keeps labels readable
Chart categories
3-4 maximum
Prevents crowding
Nested levels
1-2 maximum
Avoids complexity
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:
Element count: Can I describe this in 3-4 items or less?
❌ NO → Simplify or split into multiple graphics
✅ YES → Continue
Complexity check: Is this a multi-stage workflow (5+ steps) or nested diagram?
❌ YES → Flatten to 3-4 high-level steps only
✅ NO → Continue
Word count: Can I describe all text in 10 words or less?
❌ NO → Cut text, use single-word labels
✅ YES → Continue
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:
Title Block - Stylized title with institutional branding (optional - can be LaTeX text)
Introduction Graphic - Conceptual overview (3 elements max)
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

# 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 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:
Section
Max Elements
Max Words
Example Prompt (REQUIRED PATTERN)
Introduction
3 icons
6 words
"POSTER FORMAT for A0: ULTRA-SIMPLE 3 icons: [icon1] [icon2] [icon3]. ONE WORD labels (100pt bold). 60% white space. 3 words total."
Methods
3 boxes
6 words
"POSTER FORMAT for A0: ULTRA-SIMPLE 3-box workflow: 'STEP1' → 'STEP2' → 'STEP3'. GIANT labels (120pt+). 60% white space. 3 words only."
Results
2-3 bars
6 words
"POSTER FORMAT for A0: TWO bars: 'BASELINE 70%' 'OURS 95%'. GIANT percentages (150pt+) ON bars. NO axis. 60% white space."
Conclusions
3 cards
9 words
"POSTER FORMAT for A0: THREE cards: '95%' (150pt) 'ACCURATE', '2X' (150pt) 'FASTER', checkmark 'READY'. 60% white space."
Case Study
3 elements
5 words
"POSTER FORMAT for A0: ONE case: logo + '18 MONTHS' (150pt) + 'to discovery' (60pt). 60% white space."
Timeline
3 points
3 words
"POSTER FORMAT for A0: THREE years only: '2018' '2021' '2024' (150pt each). Large icons. 60% white space. NO details."
MANDATORY prompt elements (ALL required, NO exceptions):
"POSTER FORMAT for A0" - MUST be first
"ULTRA-SIMPLE" or "ONLY X elements" - content limit
"GIANT (120pt+)" or specific font sizes - readability
"60% white space" - mandatory breathing room
"readable from 10-12 feet" - viewing distance
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"

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:
TOP EDGE:
Title completely visible (not cut off)
Author names fully visible
No graphics touching top margin
Header content within safe zone
BOTTOM EDGE:
References fully visible (not cut off)
Acknowledgments complete
Contact info readable
No graphics cut off at bottom
LEFT EDGE:
No text touching left margin
All bullet points fully visible
Graphics have left margin (not bleeding off)
Column content within bounds
RIGHT EDGE:
No text extending beyond right margin
Graphics not cut off on right
Column content stays within bounds
QR codes fully visible
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):
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
Reduce sections:
More than 5-6 sections? → Combine or remove
Example: Merge "Discussion" into "Conclusions"
Cut text content:
More than 800 words total? → Cut to 300-500
More than 100 words per section? → Cut to 50-80
Adjust figure sizing:
Using width=\linewidth? → Change to width=0.85\linewidth
Using width=1.0\columnwidth? → Change to width=0.9\columnwidth
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)
Tested on multiple PDF viewers (Adobe, Preview, etc.)
Displays correctly on different screens
QR codes tested and functional
Alternative formats prepared (PNG for social media)

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
Determine poster requirements:
Conference size specifications (A0, 36×48", etc.)
Orientation (portrait vs. landscape)
Submission deadlines and format requirements
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
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)
Create figures directory:
mkdir -p figures
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
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
Allocate space for title (10-15%), content (70-80%), footer (5-10%)
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
Create poster header:
Title (concise, descriptive, 10-15 words)
Authors and affiliations
Institution logos (high-resolution)
Conference logo if required
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
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
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
Review and iterate:
Check for typos and errors
Verify all figures are high resolution
Ensure consistent formatting
Confirm color scheme works well together
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
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
Compile final PDF:
pdflatex poster.tex
# Or for better font support:
lualatex poster.tex
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
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
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:
Add "SIMPLER" or "ONLY 3 elements" to prompt
Increase font sizes: "150pt+" instead of "80pt+"
Add "60% white space" instead of "50%"
Remove sub-details: "NO sub-steps", "NO axis labels", "NO legend"
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!)
