Abstract

Objective To solve the conglutination problem between the hot stamping foil and the prints found with the platen press foil stamping machine. Methods The problems in the layout of stamping process were brought up, by analysis of the conglutination problem between the aluminum foil and the prints during the stamping process, in combination with the actual production. Results By the way of unidirection paper uncovering method, there was 0.5 kg/mm2 force acting between the aluminum foil and the printing products, which facilitate easy separation. Wind power was increased using a small-hole blowing tube design with a diameter of about 1~2 mm. The improved sinusoidal variable motion was used for servo tracking control. In order to facilitate the separation of the aluminum foil and the prints , the large-layout printing specific aluminum foil was used. Conclusion Ideal printing results were obtained by improving the design scheme and technology of the hot stamping process from the four aspects of paper uncovering manner, blowing system, servo system and selection of aluminum foil material, and by controlling the related factors in the printing process including velocity, temperature and pressure.
