Abstract (en)
[origin: WO2008051112A1] The invention relates to mechanically processing sheet or coiled or laminated material, in particular to stamping methods and means. The inventive method for producing a photograph-like image on metal paper or metallised material in such away that demi-tints are transmitted and the image is securely protected against counterfeit, consists in applying an image by means of a calender press, the working surface of one of the rolls of which or the working surfaces of the both rolls of which are provided with rows of projections, in forming a relief surface, the shape and the variable depth of which are determined by the reproducible original of the image according to the optical density of corresponding areas of the reproducible image, on one of the rolls by engraving and removing the material of projections within the limits of the height thereof, and in producing a like-photograph image which is differently ("negative" or "positive") perceivable according to a visual angle, and/or the type and/or the position of a light source. The variants of the embodiment of the method and the calender press are also disclosed.
