For suppliers — presses, substrates, inks, finishing
Every configured print product names its substrate, its press, its finishing. In the PTPGE specification those names are yours: a permanent identity in the open register at ptpge.org/v1/suppliers/, and a catalogue you keep current on your own domain. Systems, LLMs and buying agents configure from building blocks you helped define — and resolve straight to what you actually make.
A supplier is an entry at ptpge.org/v1/suppliers/<name>: a URI that never changes, held by the specification, free. Fourteen suppliers are listed today, from Antalis and Lessebo to Heidelberg, Komori, Ricoh, swissQprint, MGI and POLAR.
What you make lives in supplier-catalogue/1 at https://<your-domain>/.well-known/ptpge/catalogue.json: paper series with grammages and shades, press models with formats and perfecting, finishing equipment — every property a term, every term a URI.
The Supplier Profile builder writes that catalogue for you, in the specification's terms, validates it and gives you the file to host. Sign in with your e-mail; nothing to keep.
A printer's declaration names your paper by your identity; a buyer's configuration resolves to your series; a quote carries it unchanged. The Directory lists suppliers next to the printers that run their equipment.
