Hi Rich - I'm not super print savvy but I do know it's not as simple as batch converting them if the colors are at all complex and you want them to look similar - the color gamuts don't match so some colors will look off (usually darkened) because they have to be modified to fit in the new gamut. I usually bring them into Photoshop, which does an okay job of simulating print on a monitor, and tweak them, then make test prints. Sam
