I’ve been asked by a client to design a full page advertisement for a catalog. The specs I received mention that beside a PDF of the page we should also supply “imperatively a cromalin: Without a cromalin your advertisement, we will not be responsible for the quality of the printing.”
It’s the first time I’ve heard of a cromalin. Searching online reveals that it is related to prepress proofing, which I don’t have much experience with.
Can someone explain what a cromalin is and how I can make one?
It’s a DuPont proprietary colour proofing process.
It was originally a photographic process. They now have a digital version — basically a colour-calibrated high-res inkjet print.
I haven’t actually heard the term used in the fully digital (computer to plate) era though. Maybe there are just a lot more options from competitors these days.
Anyway, it’s something a printing company’s pre-press department would supply.
It may also be that the publication is using it as a generic term for a certified colour-accurate proof, or they haven’t updated those instructions for years!
