Adjust the color quality Adjust the color quality About color adjustments In most cases, a printer calibration is sufficient to deliver the required color quality. Therefore it is advised to always perform a printer calibration before you perform one of the procedures below. About calibration on page 170 (See ) Perform an automatic color mismatch correction when the print system does not execute the color alignment in the correct way. Reduce unwanted white edges between color planes with a trapping preset. Perform a manual shading correction when you want to correct the shadings close to the edges of the sheet. Daily printer calibration and media family calibration result in calibrated CMYK curves. You can perform a manual adjustment of the CMYK curves on job level or on system level. Only use the automatic correction color tone (ACCT) function to correct slight color deviations in the color tones when the calibration for maximum print quality does not deliver the required color quality.
