PRINTING SYSTEM FOR PRINTING AN OBJECT WITH A PATTERN ON A SURFACE OF THE OBJECT

A method for printing an object that is specified to have a pattern image visible at the surface of the object includes generating a plurality of layers of voxels to be printed on top of each other on a support by depositing voxel drops of marking material in order to create the object consisting of...

Zusammenfassung:	A method for printing an object that is specified to have a pattern image visible at the surface of the object includes generating a plurality of layers of voxels to be printed on top of each other on a support by depositing voxel drops of marking material in order to create the object consisting of columns of said voxel drops. Each voxel drop in a column of voxel drops is deposited in a different layer. For each column of voxel drops intended to be printed marking material is deposited for each layer in the column. For each column of voxel drops intended to be printed, it is determined if the location of a top layer of the column is intended to be part of the pattern intended to be established at the surface of the object. If so, a voxel drop deposition is paused for a predetermined number of layers within the column before the top layer of the column is printed. The remaining originally intended layers of the column are deposited after the pause of the voxel drop deposition within the column.
