everything what has to do with PDF is a miracle to me. There are some problems I have to solve but I don't find information about it.

  1. Searching for Spotcolors. Does it exist? Whats the name of it etc, is it set to "overprint"?
  2. Search for paths ( in Illustrator its a Shape with a contur with a spotcolor ) and split the closed paths to single pdf pages.
  3. Include / Exclude imageinformation within the closed path
  4. Get the size of the seperated paths.

Can somebody help to find a start on this? Where can I find information about this kind of "pdf-manipulation"?

best regards,

Rune

  • I'm assuming you're dealing with something in printing; many of these things are very familiar to me. If you need to write this from scratch without using higher-level tools, you need to at least have a look at the PDF Specification (https://stackoverflow.com/questions/14111831/pdf-specifications-for-coders-adobe-or-iso/14115129#14115129). Concepts such as spot colors are described in there, even though the terminology will be different (separation colors). You'll also need a library that will give you basic PDF support, to the level of page elements... – David van Driessche Jul 21 '20 at 14:15
  • Hello, sorry for answering so late. I did take a look at the linked documents and will try to reproduce some things. editing, deleting some lines in notepad, monitor changes to find a way to achieve what I'm looking for. – Rune Aug 12 '20 at 05:37
