Method for calibrating a color printer in which a printed digital calibration pattern can be compared with a reference pattern and a transformation between reference and printed patterns determined

摘要

Calibration method in which a digital calibration pattern (11) with color patches (22) is printed within the color space CMY by a printer (2). The pattern is evaluated in a so-called laboratory color space and a correspondence table (13) defined between the printer color space and a laboratory color space. To determine the colors in a laboratory color space the color patches are analyzed with a scanner in a defined reference colorimetric space, the colors are determined in this space and a transform from this space is defined as a laboratory space. To implement a printer calibration a PC (1) is connected via a network to a calibration server (21).
