Side note: I am colorblind.
Thank you all for your advice. I have gotten a lesser greenish grey by adjusting PF before print. Still a little green. Next I will try creating my own swatches and I believe I will also start designing in CMYK to help the rip process work less and be more accurate.
At this point I just tell customers grey looks green and try to prepare them. I don’t have the patience more the free time to block off my work flow to try and fix all of this companies problems. I have suggested hiring professionals, people who know what they are doing and they don’t want to pay. So their problem isn’t my problem until I have no other option. Right now, I just do what I can.
