1. Process for the colorimetric measurement of a two dimensional original at predetermined measuring positions, comprising the steps of: photoelectrically scanning the original pixel by pixel by way of a color-enabled photoelectric scanning device with a color measuring head being movable under computer control to produce a digital color representation of the original; determining at least one measuring position from the digital color representation; moving said color measuring head relative to the original to the at least one measuring position; and colorimetrically measuring the original at the measuring positions.
