I have already profiled the printer without calibration, but I see problems in gradients close to white when using perceptual intent (for example soft shadows on white background are not smooth). OK, if I forget about calibrating the virtual RGB channels, do you think that using result of printcal in printtarg might help with that, when only 8bit driver is available?
Yes, for an underlying CMY printer (especially if the RGB is simply being inverted to driver the CMY), then calibration/linearisation is worth a shot, even for 8 bits. (The profile typically has a much lower table resolution than 256). Graeme Gill.
