Problems solved by technology

The current hot stamping process has the following limitations: 1. The production of hot stamping plates requires a long production cycle, and multiple transfers of information are prone to changes and losses
2. It takes a long production time and a certain amount of materials to install the bronzing plate and adjust the temperature, pressure and pattern position
3. The pattern is fixed, and it is not convenient to modify the pattern information
4. Heating is required during the production process, which consumes a lot of energy

Embodiment Construction

[0023] The invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 Shown, a kind of digital ink-jet bronzing process of the present invention comprises the following steps:

[0025] Step 1, spray varnish pattern: use digital inkjet equipment to spray varnish onto the substrate to obtain a varnish pattern, and the distribution shape of the varnish on the substrate corresponds to the pattern to be stamped;

[0026] Step 2, UV light semi-cured varnish: use UV light to cure the varnish pattern prepared in step 1, so that the solid content of the varnish is 55% to 75%;

[0027] Step 3, bonding the transfer layer with the varnish pattern: press the transfer layer of the cold foil film with the varnish pattern prepared in step 2;

[0028] Step 4, separating the base film of the cold foil film from the transfer layer.

[0029] The transfer layer of the cold perm film is the anodized aluminum layer, and the base film is th...

Abstract

The invention relates to the field of gold stamping technologies, in particular to a digital ink-jet gold stamping technology. The digital ink-jet gold stamping technology comprises the following steps: step 1, a gloss oil pattern is sprayed: gloss oil is sprayed onto a printing stock by using digital ink-jet equipment, the gloss oil pattern is prepared, and the distribution shape of the gloss oil on the printing stock corresponds to that of a to-be-stamped pattern; step 2, the gloss oil is subjected to semi-solidification by UV (Ultra Violet) irradiation: the gloss oil pattern prepared in the step 1 is solidified by using a UV lamp, so as to allow the solid content of the gloss oil to be 55-75%; step 3, a transfer printing layer is bonded with the gloss oil pattern: the transfer printing layer of a cold gold stamping film and the gloss oil pattern prepared in the step 2 are laminated; and step 4, a base film of the clod gold stamping film is separated from the transfer printing layer. According to the digital ink-jet gold stamping technology, the gloss oil pattern can be changed at any moment by using the digital ink-jet equipment, so that a gold stamping pattern is changed, no plate making is required, and the production cycle is short.

Description

technical field [0001] The invention relates to the technical field of bronzing technology, in particular to a digital inkjet bronzing technology. Background technique [0002] At present, the hot stamping process in the industry mainly includes hot stamping process and cold stamping process. The principle of the hot stamping process is to transfer hot-pressed anodized aluminum to the surface of printed matter or other objects through the hot stamping plate. The principle of the cold stamping process is to transfer the graphic information with the PS plate The cold perm glue is transferred to the substrate through pressure, adhesion and peeling, and the metal foil is transferred to the surface of the substrate. The current bronzing process has the following limitations: 1. The production of bronzing plates requires a long production cycle, and multiple transfers of information are prone to changes and losses. 2. It takes a long production time and a certain amount of materi...
