I printed a flyer using several photos in it. I printed 5000 a few years ago and was lucky with the print quality. I printed another 5000 now, quality is o.k. but not as clear and detailed as wanted. Now, I'm a musician and feel a bit a bit helpless in the world of print. What's the secret? Who is the guy I go to who garantees a certain quality? I guess this is a very general question for something that's very specific for me. I'd be glad to specify but don't know how. Anyone can help?
