Problems solved by technology

There are following deficiencies in the above-mentioned bronzing process: at first it needs a Figure 1 The second is that a little stretching deformation of the substrate due to tension will cause displacement between the printed pattern and the bronzing roller, resulting in inaccurate positioning of the bronzing and product defects. For this reason, we propose a digital light roller bronzing printing art

Embodiment 1

[0030] A digital light roll hot stamping printing process, a digital light roll hot stamping printing process, comprising the following steps:

[0031] Step 1 Prepare UV curable resin, prepare UV curable resin according to process requirements;

[0032] Step 2 Prepare UV varnish, and use the UV curable resin obtained in step 1 as a raw material to prepare UV varnish for printers;

[0033] Step 3 Print the pattern, according to the requirements of the post-processing process, make the pattern that needs to be stamped into a printable file, and print it on the substrate through a UV printer;

[0034] Step 4 Make a new hot stamping film, remove the thermal transfer glue layer from the traditional hot stamping film, and set aside;

[0035] Step five is laminating and overprinting, using a smooth roller laminating machine to bond the printed substrate with the new hot stamping film prepared in step four, the material is off the roller, and the PET film is peeled off after cooling,...

Abstract

The invention discloses a digital smooth roll gold stamping printing process which comprises the following steps: step 1, preparing UV (Ultraviolet) curing resin according to process requirements; step 2, preparing UV gloss oil, namely preparing the UV gloss oil used by a printer by taking the UV cured resin obtained in the step 1 as a raw material; 3, printing a pattern: making the pattern needing to be gold-stamped into a printable file, and printing the printable file on a printing stock through a UV printer; 4, a novel gilding film is manufactured, and a heat transfer glue layer of a traditional gilding film is removed for use; and (5) laminating and overprinting: laminating a printing stock printed with a pattern and the novel gold stamping film prepared in the step (4) together by using a smooth roll laminating machine, separating the material from a roll, cooling and stripping the PET film. According to the invention, the process of the gold stamping process is rearranged, the function composition of each layer of material of the gold stamping film is reset, and the existing material technology and printing technology are utilized, so that the gold stamping process does not need to manufacture a special edition any more, and the precision problem of gold stamping overprinting is also perfectly solved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a digital photo-roll bronzing printing 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 prior art, bronzing process: A, the hot stamping pattern pressure roller must be specially made, and the protrusion is the pattern part, and the part without the pattern is concave. The bronzing roller and the light roller form a pattern-contact laminating facility; B. Let the bronzing film pass through the transmission facility and the surface of the substrate, and then contact, press, and heat through the laminating facility above; the raised pattern part, bronzing coating ...
