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.
