How to find out in PDF file?
Use the Preflight tool.
Thank you for your reply.
No, use Preflight or also try Output Preview.
Ok thank you.
Preflight or output preview is manual know. Not possible to automate using script?
The question "how many colours" is ambiguous, and may be variable. Often the answer is millions.
- You should use Convert Colors: there is a (ridiculously) small window in the upper right corner that gives you this info.
- Preflight allows the use of "Droplets", which is a kind of automation.
What do you propose to do with your list of millions of colours, in unlimted colour spaces, in up to 11 colour space families?
In this typical case, when a graphist ask about "colors" he means color spaces (RBG…) and/or Inks (C+M+Y+K+spots colors).
When a graphics artist says that, they might mean all sort of things, but a programmer needs to define the task precisely.., or so it seems to me.
In French we say: "Everyone sees noon at his door"
(Chacun voit midi à sa porte)
