Abstract: The document relates to a method of producing a product comprising a substrate with at least one 2D-patterned layer from a multilayer material (1), wherein the multilayer material (1) is passed through at least one nip (6, 6a, 5 6b), provided by a milling cutter (51, 51a, 51b) cooperating with a patterned cliché cylinder (52, 52a, 52b), to selectively remove predetermined portions of material from at least a first layer (10) of the multilayer material (1) in accordance with a pattern of the patterned cliché cylinder (52, 52a, 52b), whereby the 2D-patterned layer is formed from the first layer (10). The method comprises; providing the multilayer material (1) comprising at least the first layer (10) and a second layer (20); feeding the multilayer material (1) through a first such nip (6, 6a) to partially, as seen in a thickness direction of the first layer (10), remove at least some of the predetermined portions of material from the first layer (10); and feeding the multilayer material (1) through a second such nip (6, 6b) to remove a remainder of said at least some of the predetermined portions of material.
