Abstract: 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.

Abstract: A method of 3D ink jet printing, the method comprising a step of jetting out droplets of a curable liquid onto a substrate in positions that fit into a predetermined raster; and a step of radiation-controlled curing of the liquid, wherein the radiation is applied at spots that also fit into a predetermined raster, wherein the raster that is employed in the curing step has a higher resolution than the raster employed in the jetting step.

Abstract: A printer control system for controlling the printing of an object on a support in a number of passes on top of each other includes 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 includes a representation of the surface of the object. The printer control system further includes a digital analyser for analysing 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 for digitally shining on the pixel-precise preview. The printer control system calculates 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.

Abstract: The present invention relates to a printer control system and a method for controlling the printing of an object on a support in a number of pass images on top of each other. The object has a surface of varying height. The printer control system comprises a user interface having a display device and arranged to visualize in a window on the display device a preview image before printing of the object. The preview image comprises a representation of the surface of the object. The printer control system further comprises an analysis section which is configured to analyze the pass images in order to predict before printing the object a location of a contouring artefact at the surface of the object, and a transformation section which is configured to transform the predicted location into a contour representation to be added to the preview image. The contour representation is visually distinguishable from the representation of the surface of the object in the preview image.

Abstract: A method for printing a digital image on a media object lying on a flatbed surface of a printer, the printer comprising a print head for ejecting recording material on the media object, a camera system connected to the control unit and positioned above the flatbed surface, and a control unit for storing a digital image and controlling the printing of the digital image on the media object, the media object having a contour as seen from a point of view of the camera system towards the flatbed surface, a first point having a position on the contour at a particular height with respect to the flatbed surface, and a second point being one of a point of normal projection of the first point on the flatbed surface and a point having another position on the contour than the first point, the second point being at the same height as the particular height of the first point, and the control unit storing a distance between the first point and the second point, the method comprising the steps of capturing a camera image of

Abstract: 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.
