LaTeX Research Posters

Create a conference-sized PDF from scientific content, editable LaTeX, and verified

figures. Use for new posters, paper-to-poster adaptation, institutional templates,

and poster compilation or print preflight.

Choose the poster package

| Package | Use when | Reviewed target |

| --- | --- | --- |

| beamerposter | Beamer blocks or institutional Beamer themes fit the project | CTAN 1.13 |

| tikzposter | TikZ styling and automatically stacked blocks are useful | CTAN 2.0 |

| baposter | A supplied project uses its named, relative-positioned boxes | Archived class v2.0, 2011/11/26; upstream site unavailable at review |

The three bundled templates were compiled locally with pdfLaTeX (TeX Live 2025)

and inspected using Poppler 26.09.0. baposter was tested using the pinned archival

source described in [references/latex_poster_packages.md](references/latex_poster_packages.md).

Do not interpret an old stable package version as proof of current tagged-PDF support.

Other reference snippets are illustrative building blocks unless explicitly tested;

they require the indicated class, packages, actual data, and figure files.

Workflow

1. Establish the scientific content and output requirements

• Record exact paper width, height, orientation, venue rules, and printer requirements.
• Choose 1-3 main messages and the results needed to support them. A useful starting

budget is 300-800 words with 3-5 figures; adjust to the audience and available space.

• Preserve study design, sample sizes, units, effect sizes, uncertainty, limitations,

and data provenance. Include the relevant citations, contact, and acknowledgments.

• Use actual analysis outputs for plots and original research images for evidence.

Do not use an image model to invent numerical charts, microscopy, spectra, or results.

2. Prepare and review figures

Prefer vector PDF for numerical plots, TikZ for precise diagrams, and suitable PNG/JPEG

for photographs or conceptual artwork. Convert SVG to PDF before ordinary

\includegraphics; SVG is not a directly supported pdfLaTeX image format.

Optional AI schematics can help explain a concept. Generate them only when useful;

there is no required AI-image quota. Keep titles, citations, numerical values, and QR

codes editable in LaTeX or a deterministic plotting tool. Use official logo assets.

The helper uses OpenRouter's POST /api/v1/images with Nano Banana 2

(google/gemini-3.1-flash-image) and reviews through POST /api/v1/chat/completions

with google/gemini-3.7-flash. It accepts PNG output paths and 1-2 iterations.

Generation and review both consume API credits. A saved image or an AI score does

not establish scientific correctness or final print quality. Check the image and

*_review_log.json, including quality_met and termination_reason.

Inspect every figure before assembly: relationships, labels, units, colors, license,

and accuracy. Check actual placed size, pixel dimensions, and raster PPI. A requested

“120 pt” font in an image prompt is not a physical typesetting guarantee. See

[references/ai_graphics_for_posters.md](references/ai_graphics_for_posters.md).

3. Create the layout

Copy one of the three files in assets/ into the project:

• beamerposter_template.tex
• tikzposter_template.tex
• baposter_template.tex

Each template compiles with visibly marked draft figure boxes when its assets are

missing. These are placeholders, not example research findings. Replace them,

example references, author details, logo boxes, and the example QR target before delivery.

Use 2-3 columns as a starting layout. Keep sufficient page margins and gaps between

blocks. Figure widths must fit the containing box; 0.85\linewidth is a reasonable

starting point, not a universal maximum. Body text around 24-36 pt at final print

size is a starting range. Font commands vary with class and scale; verify the actual

rendered sizes rather than assuming that \Large is always a fixed size.

Package details, valid option keys, and layout caveats:

[references/latex_poster_packages.md](references/latex_poster_packages.md).

4. Compile and inspect the actual PDF

Run these from the poster project directory:

pdflatex -interaction=nonstopmode -halt-on-error poster.tex
pdflatex -interaction=nonstopmode -halt-on-error poster.tex
pdfinfo poster.pdf
pdffonts poster.pdf
pdfimages -list poster.pdf
pdftoppm -scale-to 2000 -singlefile -png poster.pdf poster-preview
rg -n 'Overfull|Underfull|Warning|undefined' poster.log

Use LuaLaTeX/XeLaTeX if a project needs fontspec and installed OpenType fonts;

changing engines still requires compilation and visual verification. Run BibTeX

or Biber only when the bibliography setup calls for it.

Open the rendered page and inspect all edges, column boundaries, figure labels, and

footer. Overfull boxes require investigation; they do not always imply page clipping.

TikZ/baposter overlaps can occur without overfull warnings, so a clean log is insufficient.

An underfull box is a spacing diagnostic, not automatic evidence of clipped content.

Run the bundled read-only preflight using its absolute path:

bash /path/to/latex-posters/scripts/review_poster.sh poster.pdf

Exit status is 0 when automated checks pass, 1 for failures such as unreadable PDF,

multiple pages, or unembedded fonts, and 2 when required Poppler tools are absent.

The script reports all fonts and placed raster PPI. It does not certify accessibility,

PDF/X compliance, scientific accuracy, QR destinations, or absence of overlap.

5. Proof and deliver

• Compare exact PDF dimensions with the venue specification and confirm one page.
• Check all emb entries from pdffonts; rebuild offending fonts in the LaTeX or

imported figure source. -dEmbedAllFonts=true is a Ghostscript option, not pdflatex.

• For raster artwork, calculate PPI at placed size; use the printer's requirements.

A 300 PPI target is useful for close inspection, but vector figures have no raster PPI.

• A0-to-A4 is approximately 25% linear scale. A 36×48-inch poster becomes 9×12 inches

at 25%, so it does not fit Letter paper at that scale. Judge reduced proofs from

the same scale factor times the intended full-size viewing distance.

• Confirm color profile, bleed, and any PDF/X variant with the printer. Preserve the

original when making a compressed or color-converted copy and recheck the result.

• Provide the PDF and its reproducible source/figure bundle. Add an accessible text

summary if digital accessibility is required; a caption alone is not PDF tagging.

Use [assets/poster_quality_checklist.md](assets/poster_quality_checklist.md) and

[references/compilation_and_quality_control.md](references/compilation_and_quality_control.md)

for final checks.

Installation

# On an existing supported TeX Live installation; distribution permissions vary.
tlmgr install beamerposter tikzposter qrcode graphics xcolor booktabs
# Check available classes before selecting a template.
kpsewhich beamerposter.sty
kpsewhich tikzposter.cls
kpsewhich baposter.cls

Do not assume tlmgr install baposter is available. Obtain a trusted baposter.cls

with its license and record its revision, or use a bundled TeX Live poster package.

MiKTeX may offer missing packages on demand, depending on its configuration.

Install Poppler (pdfinfo, pdffonts, pdfimages, pdftoppm) through the platform's

package manager. Optional schematic calls additionally need requests and the

OPENROUTER_API_KEY environment variable; never put credential values into poster sources.
