How often should the IT-8 calibration be accomplished in a scanner?
A scanner only provides good and real colour values if it is calibrated with the support of an IT-8 calibration target. But how often has such an IT calibration to be accomplished, is it a procedure that has to accomplished once or repeatedely? All scanners have a certain radical error that is a certain grade of deviation in terms of colour that is construction-conditioned and that is within certain range of tolerance of the model range. This radical error is compensated by a unique IT-8 colour calibration. But the features of the scanner change in the course of its life. As it is the case in a screen where the colours wash out or bleach a little in the course of the years, the colour representation of a filmscanner decreases in the course of the months and years. In order to compensate this creeping error, one should accomplish the IT-8 calibration once a month. Those who attach highest importance to an absolutely real colour rendering in the scanning should accomplish an IT8 colour c
