Since the color of the paper on the monitor is simulated by white in the RGB model the main thing is to use the white point temperature to achieve the maximum match between the color of the paper in the lighting conditions in this room and the white color on the monitor. This is necessary for a correct comparison of the screen and print choosing a balance between warm and cool colors is the only way to control the hues of your screen environment. Gamma To adjust the overall tone of the screen use the field or gamma. This gamma has nothing to do with linearization but adjusts the average tone of the monitor for a particular type of print.
This is the main parameter that controls the brightness of the e-commerce photo editing onscreen display see Scan Algorithm. Gamma also behaves like dot gain in print see Color Correction Methods increasing it darkens the image. It could be used to simulate dot gain but then it would also affect RGB images which are usually not used for printing. Scanner Calibration IT scale for calibrating scanners IT scale for calibrating scanners Kodak has developed a special IT scale for calibrating reflective and transmissive scanners. It is enough to scan this scale without using correction in the scanning program and special programs for example Magic Match by UMAX will build a profile based on the scan and the numerical values.
Problem when working using a profile in many scanning programs you lose the ability to configure a large group of parameters and the scanner turns into a measuring device suitable only for digitizing standards. As you know there are practically no such originals. If scans have a permanent color fog or an incorrect tonal response this can be verified by scanning a gray scale then it is better to compensate for the defects using curves in the scanning program and save the settings as a calibration. One should not only achieve absolute accuracy in all gradations points on the curve are enough. Otherwise the picture can only lose.
