A method for producing a material board, which has a structured, colored surface, assigns image data to a colored digital image of a colored original surface. The image data is used to produce a first image data set and at least one second image data set, which are each assigned to different color channels of the colored digital image. A colored surface is produced on a base carrier using the at least one second image data set but without using the first image data set. The colored surface of the base carrier is pressed by use of a structured pressing surface of a pressing tool, in order to obtain the material board with the structured, colored surface. The structured pressing surface is assigned to the first image data set.
