Method for controlling color at zonal inking unit in printing machine, involves measuring color values in image region similar to reference values for controlling color at zonal inking unit in printing machine by control computer

摘要

The method involves providing color measurement fields (11) in image region (16) on a substrate (4). The color values in the image region are measured by a color measuring device (1). A control computer is provided for determining reference color values by comparing color values of artwork with measured color values. The color values in image region are measured by other color measuring devices similar to reference color values such that the color at zonal inking unit in printing machine is controlled by control computer.
