If you perceptual intent it will make no difference (in practical - not scientific terms) whether it's turned on or off. If you use RelCol you will need BPC to avoid tone clipping. > > And finally, if one or both of these functions is operating properly, why > am I still frequently obliged to manually target files to the maximum > shadow and minimum highlight points of the printer-ink-paper combination? Are you using a high quality custom profile? If not then that should be your first step. You should always finetune your image with softproof turned on (simulating paper white and ink black) using the correct rendering intent (the one you will use for conversion to print space). This is the best possible way to predict printingresults - without printing...
