Hot stamping technique

Abstract

The invention discloses a hot stamping technique, and belongs to the technical field of printing. The hot stamping technique comprises the following steps that (1) proper electric aluminum foil is selected according to the material of a printed article; (2) in a vacuum environment, a gloss oil pattern is sprayed on the printed article, and UV curing is conducted; (3) a hot stamping plate is mounted on a honeycomb plate; (4) the honeycomb plate and the hot stamping plate are mounted at corresponding positions of a hot stamping machine; (5) the electric aluminum foil is mounted; (6) hot stamping technological parameters are set and the honeycomb plate is preheated to the temperature of 110 DEG C firstly, and then hot stamping is conducted on the printed article obtained in the step (2); (7) trial stamping is conducted, and the parameters are adjusted according to a hot stamping result till a product is qualified; (8) sample signing is conducted; and (9) normal hot stamping is conducted. By adoption of the hot stamping technique, dust in air can be prevented from adhering to gloss oil in the gloss oil spraying process and the gloss oil drying process, so that the surface of dried gloss oil is smooth, and the situation that since the pattern is irregular, gloss oil is accumulated in pits of the pattern or small gloss oil particles are formed on the edges of the pattern in the gloss oil spraying process, and the spraying effect is affected is avoided.

Description

technical field

[0001] The invention belongs to the technical field of hot stamping, and in particular relates to a hot stamping process. Background technique

[0002] The hot stamping process uses the principle of heat transfer to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to form a special metal effect. Because the main material used for hot stamping is anodized aluminum foil, hot stamping is also called anodized aluminum hot stamping.

[0003] In the printing industry, hot stamping of anodized aluminum foil on paper is commonly used, which is called hot stamping, and hot stamping is a general term for a process. Bronzing does not mean that what is hot on is golden. There are many kinds of hot stamping paper materials, including gold, silver, laser gold, laser silver, black, red, green and other styles.

[0004] In the existing hot stamping process, it is generally used to apply the varnish after hot stamping. However, due to the...
