I've made labels in illustrator for my workplace. The only way the staff will be able to print them is if I make them into PDFs. I did this for about 50 labels, but when I try to print them from PDFs the colors come out faded. We print on Toshiba E-Studio7506ACT printers. I'm not sure if there are optimal settings I can use when exporting from illustrator, but I have tried following a few guides to no avail. My document is CMYK, contains no images, Really need some help here. Thanks!
