Title:
IMAGE PROCESSING METHOD FOR THREE-DIMENSIONAL PRINTING
Document Type and Number:
WIPO Patent Application WO/2010/079017
Kind Code:
A3
Abstract:
A relief print master is created by printing a sequence of layers on top of each other by means of an inkjet printing system. The top layer corresponds with the binary halftoned image that is to be printed by the print master and the lower intermediate layers are supporting layers. The features in a lower supporting layer have an area that is larger than the corresponding features in a higher supporting layer. A circular spread function is applied on the features of a higher intermediate layer to increase the area of the features in a lower intermediate layer. By using a sequence of two non-circular spread functions, the circular spread function is approximated and the number of required calculations can be reduced.
