I remeasured the target, and everything went fine. However, I then printed the provided test image, doing the four quadrant method and changing the rendering intents for each image. Each of the images states a different intent, i.e. saturation, percetual, etc. All four images look identical in color, tone, saturation, etc. Is this correct? I think it depends on how good your ink and paper are; the better they are the smaller the difference. Absolute Colorimeteric has a different white point to the others, so the light tones may look blue compared to the other 3, but it depends on how yellow your paper is. The 2 Colorimeteric intents assume infinite brightness range, so shadow detail may be lost. Saturation and Perceptual assume a limited brightness range which should preserve the shadow detail. On the full photodisc image the top right has lots of dark objects, but its not printed by PrintFIX PRO. There is a dark object below the hand, an elephant, I can see slightly more detail in the Perceptual and Saturation prints. I think I can see a slight difference in colour of the leather case between Saturation and Perceptual, but its not significant. On the full photodisc image I can see a difference in the colour of the printed circuit board. Mike
