IMAGE EMBOSSING METHOD ON SHEET MATERIAL BY METHOD OF STAMPING (VERSIONS), CALENDER FOR ITS IMPLEMENTATION (VERSIONS) AND PRODUCT, RECEIVED BY THIS METHOD WITH USAGE OF CALENDER (VERSIONS) Russian patent published in 2009 - IPC B44C1/24 B31F1/07 B41M3/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to field of mechanical treatment of sheet or roll or laminated material, particularly to methods and facilities of mechanical deformation without removing of the material, for instance for stamping, at implementation of claimed image embossing method, creating image of copied original (pictures, photographies) with transfer of halftones, on to strip or belt made of foil or laminated material with metallic external layer, image is embossed with usage of calender, allowing driving and at least one driven shafts, on working surface of one or on working surfaces of both shafts there are implemented projection lines, herewith at one shaft by means of engraving with removing of projection materials (by curved surface or planes) in the range of its height it is implemented embossed surface, shape and variable depth of which is defined according to copied image original additionally depth of embossed surface in places of projection materials removing, is located depending on transmission density of corresponding sections of copied image and is situated in the range of value, corresponding the location of projection foundation, up to the zero value, corresponding the location of projection vertex, with implementation on treated material of stamping variable depth, providing the effect of imitation of different levels of grey, corresponding to darker or lighter sections of original of copied image, with creation of image, similar to photography, differently ("negative" or "positive") interpreted depending on observation angle, and/or of kind, and/or of light source location. It is described also the other version of method, calenders for method implementation and stamped material, made of described methods with usage of declared calenders versions.

EFFECT: creation of method and calender, providing receiving on foil or metallise material of image like a photo, allowing high degree of protection against imitation.
