A funny idea :-) That would be cool, but I fear you will have to purchase a colorimeter or spectralphotometer to calibrate your display. I doubt that this approach you suggest will work good enough. At a first glance this might work, _but_ a scanner is basically a densitometer. This means it measures just the intensity of _some_ RGB sensors. Those sensors normally don't match the CIE-curves (in german "Normspektralwertkurven", maybe somebody helps me out with the correct english word, ah, I think it was "color matching functions") and therefore the ICC profile would have to be generated with a target which has the same spectral characteristic like your TFT display. But ICC targets for scanners are photographic materials with a totally different spectral power distribution compared to the TFT. So your clever idea won't work :-( Your solution might work in some way and _might_ somehow give you a more or less calibrated display, but I guess a good visual calibration/profiling of a display will achieve better results overall. (Besides that we still didn't discuss other aspects like the depth of focus of the scanner or other effects which might come into play.) BTW, does somehow has good experience with visual calibration/profiling of a display? So far the profiler in Mac OS X and the ICCSync solution from GretagMacbeth might be the most accurate solutions and neither will achieve the same quality like a hardware solution. Does anybody know other/better solutions?
