PRINTING SYSTEM FOR PRINTING AN OBJECT HAVING A SURFACE OF VARYING HEIGHT

The present invention relates to a printer control system for controlling the printing of an object on a support in a number of passes on top of each other. The object has a surface of varying height. The printer control system comprises a user interface which has a display device and is arranged to visualize in a window on the display device a pixel-precise preview image before printing of the object. The preview image comprises a representation of the surface of the object. The printer control system also comprises a digital analyser which is configured to analyse the pass images in order to deduce before printing of the object locations of smooth areas at the surface of the object, and a preview emulator which is configured to digitally shine on the pixel-precise preview, The printer control system is configured to calculate a digital move path to be applied by the preview emulator over the pixel-precise preview based on the locations of the smooth areas in order to highlight regions of interest with a potential print artefact.
