Zusammenfassung:	A printing system and method of printing a digital image resulting in an elevated print on a support. The elevated print has a surface of varying height. The printing system is configured to print a number of pass images on top of each other in a number of passes. The definition of the digital image comprises color data for each pixel of the digital image and height data for indicating a height of each pixel of the digital image. A raster image processor is connected to the printing system and rasterizes the digital image into a raster image. A digital slicer is connected to the printing system and derives from the raster image a number of pass images to be printed on top of each other. The printing system is then printing the pass images on top of each other by applying a number of recording materials on the support. The printing system receives information related to the print order of the recording materials in the pass images for each pass pixel for establishing a special effect. From the received information the print order of the recording materials in the pass images for each pass pixel is derived and the recording materials are printed according to this print order for each pass pixel of each pass image.
