Six open-source PDF tools. Primarily AGPL-3.0+. Self-host or use the hosted API.

PDF preflight engine with 500+ checks across image resolution, color, fonts, packaging barcodes, regulatory fields, and conformance standards (PDF/X, Ghent Workgroup). OSS engine lint-pdf v0.1.0b20 on PyPI. Hosted SaaS tier available at lintpdf.com.

• 500+ preflight checks across image, color, fonts, packaging, barcodes, regulatory, conformance
• AGPL-3.0+ engine on PyPI: install lint-pdf, run it yourself
• Hosted API: send PDF, get structured report back
• Self-hostable: run the engine on your own infra
• Integrates with AE and Cloudflow via REST or hot folder

PDF build and assembly layer — producing print-ready PDF from structured input. Beta; public roadmap available on GitHub. Email for early access.

Beta — features and pricing are not yet published. See the GitHub repo for current state. Email hello@printwithsynergy.com for early access.

Authoritative, read-only PDF extraction and rendering reference — structured facts, color resolution, geometry, and separations via Python package, CLI, HTTP API, and TypeScript client.

• CLI: extract, probe, render (page, separations, heatmap, layer), color resolve, Pantone match
• HTTP API with TypeScript client mirroring the Python surface; SSE streaming for probe and extract
• Cloudflare Worker cache layer (codex-edge) and Redis-Streams speculator for pre-warming
• Versioned schemas (document, color, geom) in schemas/v1/
• AGPL-3.0+ — self-host, fork, integrate

Plugin-driven canvas PDF viewer built around React 19 — multi-DPI tile cache, CMYK + spot separations, TAC heatmap, per-ink densitometer, OCG layer toggles, annotation canvas, and mobile-first layout.

• Page raster with multi-DPI tile cache — zoom never degrades the image
• Color picker: RGB readout + per-ink breakdown (CMYK + any declared spot inks)
• TAC heatmap and per-ink separation toggles (process + spot plates)
• Annotation canvas: pen, arrow, rect, ellipse, text, highlight, sticky note — all in-memory
• Mobile: tools collapse to slide-in drawer; readouts swap to bottom sheets

Open-source benchmark kit for PDF preflight engines — generates a deterministic GWG 2022 test corpus, runs it against your engine, and scores accuracy with TP/FP/FN/TN metrics. MIT-licensed.

• ~175 test PDFs: 23 GWG 2022 positive baselines + 152 negative failure-mode files
• 39 rules across 23 GWG 2022 variants — geometry, overprint, fonts, color, resolution
• Benchmarks callas pdfToolbox, Enfocus PitStop, and LintPDF
• TP/FP/FN/TN scoring per rule, per variant, per engine
• Reproducible markdown and HTML reports — byte-identical from seed
• SHA-256-verified provenance — all PDFs verapdf-validated against PDF/X-4

WYSIWYG canvas editor for label and packaging artwork. PDF/X-4 output, built-in flexo print support, and a full create-to-RIP workflow. AGPL-3.0+; self-hostable.

• PDF/X-4 output via Ghostscript — print-ready from first render
• Flexo distortion compensation per separation — automatic plate correction
• CF2, DDES, and ARD dieline format support
• Pantone, white ink, and varnish as named separations with preview thumbnails
• Variable data support for dynamic label content
• Embeddable as @printwithsynergy/artwork-pdf-editor — Docker Compose self-hosting
