I have been fighting my Epson Stylus Pro 7800 for a couple weeks now. My colors are way out. All of my blues are purple. It seems that my Magenta is way to strong and Cyan is too low, also my yellow looks dirty and has a green tint to them. I am having customers start to get concerned when they see this because they know thats what we usually match on press. The funny thing is if I do not go in and photoshop the files to look good on the proofs they are perfect on press. Is there anything I can do to adjust the color of my proofs? I am using Proofmaster Mezzo program that is running the Epson after it is ripped in Rampage V12. Anyone got any suggestions?
