Once you have correctly positioned the mask you can start the IT8 calibration process by pressing the “start” button. If your target is upside down or back to front you can move the corners to match the current position of the target, just make absolutely sure the white point is positioned onto the white patch of the grescale as well as the black point onto the black patch. Now you will simply adjust the corners of the mask to match the color patches of the IT8 target. In this case the automatic IT8 calibration must be deactivated by openning the options dialogue/automatic panel and unticking the checkbox for Auto-IT8 calibration. Manual calibration must be performed when using targets not produced by LaserSoft Imaging. There are two possible ways of calibrating and both are pretty straightforward. You can IT8 calibrate for positiv reflective (flatbed scanners only) and positive transparent as well as Kodachrome transparent. These can not be used to calibrate your scanner with SilverFast (LaserSoft Imaging also sells high quality IT8 targets which allow for automatic IT8 procedure at a reasonable price). Some packages include this kind of combination. Some manufacturers make targets which are conform but their reference file is not (or the other way around).

Have the IT8 calibration tool in SilverFast, I should mention, the IT8 calibration is not standard in SilverFast, it is an extra tool that can be purchased as an upgrade to all SilverFast versions where it is not present and is available for all scanners.Īn IT8 calibration target and its reference file, both must be stardard conform. Requirements to IT8 calibrate the scanner These might be reflected in light up to stark color changes, these can be corrected by color profiles generated for the specific conditions. Things like temperature and humidity might also affect the operation of the scanner, also the internal lamp changes the temperature of the scanner and its components. These changes are reflected in light color inaccuracies which can be corrected by generating new color profiles for the scanner

Construction parts age and with it the way these devices “see” things. Although Color Management is a very extent topic, I will briefly mention three good reasons for an IT8 calibration:
