INK JET IMAGE PRODUCING DEVICE AND PROCESS FOR ITS OPERATION

摘要

An ink jet image producing device for reproducing digital image data of photographic images is disclosed with at least one printing head (32) which has more than three bas e colors or ink jet colors available which stretch a color space. A processing device determines the location or color coordinates of color values of the image data in the image space which is stretched by the colors of the printing head. A determining device determines with which base or ink jet printing colors or mixtures or with which densities thereof the color values of the image da ta can be reproduced. A threshold device (20) is provided which has at least one threshold for a degree of coverage or the like of at least one printing medium. An analysis device analyzes whethe r a determined color set requires a large or small amount of ink so that the threshold device can select for the printing medium one of the color sets in dependence of the threshold for the printing medium while a printing head control device is used for printing the image data by way of t he printing head and with the selected color set.
