Hello. I'm a freelance graphic designer. For those who work in the printing process, what tips can you share with me so that I can make sure my designs look great in print. I deal directly with clients and they usually just get my files and take it to the printers. I don't speak with the printers. And most of the time I get blamed if the print looks bad. Colors are all wrong, crop/trim areas are all wrong. I'm not proud of my work because most of the time, print output is bad. What instructions can I give to clients to give to their printers?
