Claim One:
1. A method for generating a relief print on a substantially flat substrate ( 201 ), wherein palpable differences exist between a height of various parts of the relief print, by a printer ( 5 ) comprising a number of colorants including a white colorant, said printer being configured to print a relief print in a number of passes, the method comprising the steps of: defining a rasterized relief image, comprising customary color channels for indicating a color of each pixel and a height channel for indicating a relative height of each pixel of the rasterized relief image; determining a height parameter for establishing an absolute height scale; discriminating in the rasterized relief image for each pixel from the substrate to the surface of the relief image a relief part ( 202 ), a white part ( 203 ) and a skin part ( 204 ); deriving from the rasterized relief image a number of pass images ( 106 ) to be printed on top of each other, each pass image comprising pass pixels ( 103 , 104 , 105 ) for which a colorant composition is established based on a part of the pixel to which the pass pixel contributes; printing said number of pass images by applying said established colorant composition on a position of the substrate ( 101 ) associated with a pixel in the relief image, wherein the relief part comprises an arbitrary colorant composition, the white part comprises mainly white colorant and the skin part comprises colorants according to a color as defined in the color channels.
