GutenLex · Built on PTPGE · CC BY 4.0 · REST API · MCP server · UCP capability
GutenLex builds on PTPGE, the open specification of print — one meaning across every language of print, becoming the backbone vocabulary of the print and graphic-arts industry and a new way of doing business. Suppliers are a vital part of the value chain of every printed product: the specification names you with a permanent identity, and systems, LLMs and AI agents configure everything from building blocks you helped define — resolving straight to the catalog you keep current.
Create your Supplier Profile → Get in touch
No application, no key: open the Supplier Profile builder and declare your catalog. To publish you sign in with your e-mail — one click in your inbox, nothing to keep. Early adopters shape the specification — and the register remembers who was first.

Why join

Be the source, not a copy

Your identity is a canonical term in the open PTPGE specification — permanent URI, published with attribution. Your catalog is a sealed Supplier Profile you declare yourself: machines and material series, updated the day you launch them, never scraped and guessed.

Visible where decisions are made

PSPs, marketplaces, LLMs and AI agents configure printed products from the specification's building blocks — and resolve your identity straight to the catalog you declare. Your machines and materials are part of every quote.

Free, open, yours to steward

Your identity lives in the open specification (CC BY 4.0, held by PTPGE, a non-profit association); your catalog lives in your own profile — no fee, no review queue, no lock-in. The generic building blocks your products embody — materials, coatings, technologies — still enter the specification through you, with your trade names as searchable aliases.

How it works
1

Open the Supplier Profile builder on gutenlex.com — sign in with your e-mail when you publish, nothing before.

2

Claim your identity and declare your catalog — machines, substrates and material series, with technology link and core specification.

3

Your identity and the generic building blocks are published in the specification after review, attributed to your brand. Your catalog goes live in your sealed Supplier Profile the moment you publish it.
