I am working on a small booklet in InDesign which contains around 20 small examples of work completed in Illustrator, pdf and other formats.
At prepress some of the pictures are showing as RGB, even though the Package report in InDesign says "0 use RGB space".
When I opened some attached files in Illustrator they were in RGB, which I changed to CMYK. However, I cannot open in Illustrator some of the pdf pictures because I do not have some of the fonts.
How can I check a 3rd party PDF to see that it is in CMYK or RGB and if in RGB, how can I change it to CMYK.
And why is InDesign showing that "0 use RGB space" when some attached pictures/logos are in RGB space?
Thanks for any help.
