Save PDFs in Black and White
Currently to get my pdfs in black and white I either have to edit each photo individually or I have to export it from indisegn, pull into photoshop, turn black and white, then bring it into illustrator to save as a pdf. This is ludicrous. There should just be an option to save a pdf of the document in black and white. This has been on the community boards for over 4 years and still isn't done.
You can export in grayscale, see settings in picture. Try different "Dot Gain XX%" for different grayscale output (i use 15, 20 or 25, based on content).
