Method of printing with gloss control

Abstract

A method of printing a color surface of an object by printing dots of curable ink in several superposed layers includes defining a micro-texture, the micro-texture being a repetitive pattern of elevated parts and depressed parts; establishing a gloss function that indicates a gloss value of a surface having the micro-texture, as a function of a height difference between a maximum height of the elevated parts and a minimum height of the depressed parts of the micro-texture; assigning a target gloss value to at least a part of a surface area of the object; determining, on the basis of the gloss function, a required local height difference corresponding to the target gloss value; and forming, on the at least a part of a surface area of the object, the micro-texture with a height profile scaled to the required local height difference.
