Abstract: A method is provided for processing a rasterized relief image, comprising customary color channels for indicating a color of each pixel and a height channel for indicating a height of each pixel into several pass images that are printed using a printer with several colorants including a white colorant. For each pixel a relief part, a white part and a skin part are discriminated in order to combine the demands for height and color variation across the surface of the image. The skin part comprises pixels for which a colorant composition based on the color channels of the rasterized relief image is established. In order to print a color in the skin part that is independent of a height of the pixel and independent of the colorant composition of a neighboring pixels, pass images are composed that include only neighboring pass pixels that do not disturb the color forming of a pass pixel contributing to a skin part.

The skin part comprises pixels for which a colorant composition based on the color channels of the relief raster image is established. In order to print a color in the skin part that is independent of a height of the pixel, the relief part comprises an arbitrary colorant composition and the white part comprises mainly white colorant.

Abstract: A method for generating a relief print on a substantially flat substrate, wherein palpable differences exist between a height of various parts of the relief print, by a printer configured to print a relief print in a number of passes includes defining a rasterized relief image, comprising customary color channels for indicating a color of each pixel and a height channel for indicating a height of each pixel of the rasterized relief image, determining a low spatial frequency height component in the height value of a pixel of the rasterized relief image, subtracting the determined low spatial frequency height component from the relative height value of a pixel of the rasterized relief image, resulting in a relative reduced height value, and printing the rasterized relief image by using the relative reduced height value. A printing system is configured to execute the method.

Abstract: A method is provided for controlling the ejection of ink drops from an inkjet printhead. The printhead comprises an array of ink chambers with nozzles arranged for applying a row of ink dots on a receiving medium using a control signal. The method comprises the steps of labeling a nozzle as a functioning nozzle if the nozzle, upon activation by a control signal, ejects an ink drop within predefined specifications, otherwise labeling the nozzle as a failing nozzle, and distributing a control signal associated with a failing nozzle to a neighboring nozzle to maintain a local optical density, wherein said control signal associated with a failing nozzle is not distributed to a neighboring nozzle, if a neighboring nozzle of said failing nozzle is also labeled as a failing nozzle.
