Look and study Mike's post #8 and please please give the ad. dept. a ring they will give you more info on the process. There're are only 2 programmes that I would trust to give me the correct output for this job Quark, which I haven't used and InDesign which I have and I worked on a Scottish national newspaper for more than 2 years doing crappy ads that you see towards the back of these once a week mags. They also have employees whose jobs are to work on colour to produce a more consistent look and know far more than I did about the job to maintain the house quality. Give the newspaper a ring and find out more.
