The article presents the results of foil embossing studies on synthetic paper. Based on the results of research, the influence of technological modes of foil embossing on the optical indicators of prints has been determined. According to the obtained results, the following regularities were found: at the heating temperature of the cliché in the range of 60-80 ºС, the transfer of the foil occurs unevenly, with indistinct torn contours, which is also characteristic of materials based on cellulose fibers; optimal reproduction of the image was obtained at temperatures of 95-120 ºС, embossing time 1 s; when the heating temperature increases above 130 ºС, the image is distorted, the material is significantly deformed, the color of the foil significantly changes, and the gloss changes, which primarily affects paper with a thickness of 200-300 microns.
