EvidenceProduct catalogue — cover, inner pages, spec tables

A security equipment manufacturer's product catalogue and website. It began as a print job and carried on into the web.
Split print and web between two suppliers and the same company starts looking like two brands. Product colours and angles diverge, the copy stops matching — and customers read the catalogue and then visit the site.
One set of cut-outs and retouching served both print and web, instead of producing it twice for two different destinations.
For a manufacturer the specifications are the product. Keeping the catalogue's table structure on the website meant customers didn't have to learn it twice.
Print can't be undone; the web can be corrected any time. So print set the reference and the web matched it. Do it the other way round and print will always come out wrong.
Product catalogue — cover, inner pages, spec tables
Today I'd keep the specification data in one place so print and web both read the same source. Back then each was edited separately, and that approach stops scaling as soon as the product range grows.
Describe the thing you're currently stuck on. I'll reply by first separating what I can take on from what I can't.
