SYSTEM AND METHOD FOR THE DIGITAL CREATION OF A PRINT MASTER BY MEANS OF A LIQUID DROPLET DEPOSITION APPARATUS

摘要

A relief print master is created by means of a printhead that moves in a slow scan direction. The nozzles of the printhead jet droplets of a polymerisable liquid on a rotating drum. The different nozzles jet droplets simultaneously on different layers that have different diameters. As a result, the droplets jetted by different nozzles travel over a different distances before landing. The effect of this is that the droplets undergo different position lag as they land on the different layers. By rotating the printhead in a plane that comprises the central axis of the rotating drum and a nozzle row this effect can be compensated for.
