I found some posts about this (like pdfx: CMYK color profile in PDF/A) but I'm not sure it applies to my case.
Here is the context :
- I'm a designer and I'm working on a mixed Adobe/LaTeX workflow
- I intend to produce the aesthetics in Adobe Illustrator and insert them as pdf background (I found this topic : https://tex.stackexchange.com/questions/278620/how-to-insert-a-pdf-as-ba~~kground).
- The text is to be parsed by LuaLaTeX from a .csv file (this part is managed so far) so it will appear on top of the graphics.
- I need a Fogra39 (iso coated V2) colour profile for the printing compagny I'm working with
Background pdf graphics will be output in CMYK Fogra39 but I don't know how to ensure that the final output LaTeX will give me will be also in Fogra39.
Any idea ?
