Which conditions are necessary for the printer profiling of SilverFast?
Since the version 6.6, Silverfast offers optionally the possibility for the printer profiling. Therefore, a special test chart with 1026 colour fields is printed in the printer that will be calibrated and scanned afterwards. SilverFast compares the colour values provided by the scanner with the target colour values that were printed out and from the computed differences, an ICC-colour profile for the printer is created. If this ICC-profile is from then used for the printer, one gets colourfast printouts. Of course, an important condition is that the scanner with which the printed test chart is scanned is IT-8 calibrated. Only if the scsanner does not produce any colour errors due to the IT8-colour calibration, the scanned original can be used for profiling the printer. Otherwise, the scanner errors are transferred to the printer and one gets falsified print-outs, also in case of the images that do not come out of the scanner. A further condition is that the flat bed scanner must be of
