I used Gerber Omega for 99.5% of my artwork but I am having a problem with color printing for proofs for customers. Everytime I try to show white or clear enamel background, it prints as shaded. I then have to explain to the customer that the gray shading they see is really white. Gerber hasn't been very helpful, although they lead me through changing some of the settings and the shading isn't quite as dark. Anyone have any suggestions? On the color proof...how can I show white as white?
