Abstract

The invention discloses a method for carrying out hot stamping on a printed product, and belongs to the technical field of printing. The method comprises the steps that a printing material is firstlyflatly spread on a printing table face, UV base oil is printed on the surface of the printing material, the UV base oil is cured on the surface of the printing material through UV illumination, then hot stamping plates are selected according to patterns for hot stamping, after films are precisely aligned to the positions of the hot stamping plates, the hot stamping plates are riveted to a honeycomb plate, and then the honeycomb plate with the hot stamping plates is mounted at the corresponding position on a gold stamping machine; hot stamping foil is mounted on a guide roller of the gold stamping machine, and then one end of the hot stamping foil is drawn to a winding roller; and finally the cured printing material is placed on a bearing table of the gold stamping machine, and after gold stamping process parameters are set, flat hot stamping is carried out on the surface of the printing material through the hot stamping foil. By means of the method, the lock-up procedures of the hot stamping plates are improved, lock-up alignment of the hot stamping plates can be simplified, plate discharging is easy, preservation is convenient, repetition is facilitated for second edition production, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a hot stamping method for printed matter, which belongs to the technical field of printing. Background technique [0002] The essence of hot stamping is transfer printing, which is the process of transferring the pattern on the hot stamping foil to the substrate through the action of heat and pressure. Hot stamping foil, also known as anodized aluminum, is generally composed of five layers of different materials, the first layer of base film layer, the second layer of peeling layer, the third layer of coloring layer, the fourth layer of aluminum plating layer, and the fifth layer of hot-melt film When hot stamping, the hot-melt film layer of the hot stamping foil melts to form adhesion with the surface of the substrate, and the exfoliation layer melts to separate the colored layer from the base film layer, leaving the aluminized layer and the colored layer on the substrate. Because hot stamping is mainly gold and silver, it is...
