I will be sending an inDesign layout that I've been working on to a printshop sometime this week.
The main elements of the book I'm doing are the greyscale illustrations on each page – all of which I've imported as tif-files into inDesign. My contractor provided this information: "I want to have my black & white illustrations on a light-yellow/sepia background".
Each page is slightly yellow-toned i.e. the master is set to light-yellow for that "ye olde" look. Should the white background from the illustration be replaced with transparency or replaced with the same yellow-tone used for the pages? I've read that some printers don't understand transparency and that transparency has been dubbed "the forbidden fruit of layouting". Does this still ring true?
I can't really finalize the project until I know for sure. The printers in China don't seem to understand my question.
