Method for directly printing on Paper drawings of Holograms or diffraction Holograms Kinetic micrograbados producing Optical effects

摘要

The printing of the micro recorder is carried out through the printing process, and the paper is transmitted through the printing group (17, 18).It consists of a printing cylinder (17) and a printing cylinder (18).said process being carried out, after wetting the paper, at a temperature and pressure on the paper that passes between said cylinders included within the bands of 90-220 ° C and 20-120kg / mm2, respectively, preferably 130-170 ° C and 40-100 kg / mm2, respectively.
