But this leads inevitably to image degradation because every single change of a finished image file means a loss in image quality. So you have to use an image editing software to correct those faults. This means that a picture from the scanner is not identical with the original. Why you should calibrate your scanner?Īs already mentioned every scanner generates image files with specific color faults. What that means and how this exactly works we want to show you on this page. In order to get a correct image file the scanner needs to be calibrated. If our output device – the monitor – is calibrated (more information on our website screen calibration) but the input device – the scanner - is not, then although we have a correct display of the image file, we do not have a correct image file itself. This process is called calibration or profiling. Eventually they also have to be adjusted with ICC-profiles. These have to be defined with a reference color space through a comparison of set and actual values. Every input and output device generates certain color faults when image data processing. To understand whats going on you have to learn a few things about colour management. In our online-shop you can buy SilverFast Ai Studio with IT-8 targets for scanner calibrations.
