Problems solved by technology

[0004] In order to overcome the existing method of making laser lines on the surface of printing materials by film printing transfer method, the whole surface of laser lines affects the conspicuous visual effect of some prominent parts of printed materials, and the aesthetic feeling is easy to be clichéd, and the existing production is partial The idea of ​​laser lines lacks feasible technical means, poor laser effects, low production efficiency and does not meet the requirements of high-speed continuous operation. The purpose of this invention is to provide an improved method for making local laser lines on the surface of printing materials, which can overcome the existing have technical flaws

Embodiment 1

[0017] This method of making local laser patterns on the surface of printing materials, the characteristics of the process steps are as follows:

[0018] ⑴ Use polyethylene terephthalate film (PET film) as the roll substrate, and use the unwinding device and winding device to control the operation of the layered film substrate in the entire process;

[0019] (2) Coating release agent on the film by coating device, select acrylamide polysiloxane and mercapto polysiloxane

[0020] Silicone composite release agent, the coating amount is controlled at 1.2-1.3g / ㎡ dry release agent, the depth of the coating anilox roll is 45-55um, the coating speed is 80-110m / min, and then passes through the drying tunnel Dry to form a release layer, the temperature of the drying tunnel is 110°C, and the preferred length of the drying tunnel is 15m;

[0021] (3) Graphics and texts are printed on the release layer by gravure printing device, and the graphics and texts are dried by a dryer;

Embodiment 2

[0028] This method of making local laser patterns on the surface of printing materials, the characteristics of the process steps are as follows:

[0029] ⑴Using the rolled substrate of oriented polypropylene film (OPP film), the operation of the layered film substrate in the whole process is controlled by the unwinding device and the winding device;

[0030] (2) Coating release agent on the film by coating device, select acrylamide polysiloxane and mercapto polysiloxane

[0031] Silicone composite release agent, the coating amount is controlled at 1.2-1.3g / ㎡ dry release agent, the depth of the coating anilox roll is 45-55um, the coating speed is 80-110m / min, and then passes through the drying tunnel Dry to form a release layer, the temperature of the drying tunnel is 110°C, and the preferred length of the drying tunnel is 15m;

[0032] (3) Graphics and texts are printed on the release layer by gravure printing device, and the graphics and texts are dried by a dryer;

Abstract

The invention relates to a method for making local laser marks on the surface of a printing material and aims to overcome the defects that the laser marks on the entire surface in the prior art affect the conspicuous vision of a projecting part of a printed product and the conventional thought for making the local laser masks lacks a practical technical measure, has poor laser effect and low production efficiency and is not accordant with high-speed continuous operation. The technical scheme comprises the following process steps of: selecting a specific membrane; coating a release agent on the membrane; printing pictures and texts on a release layer; making a laser mask layer; coating glue on the laser mask layer; compounding the membrane with the printing material; stripping the membrane; and transferring the pictures and texts and the laser mask layer onto the printing material. The method is characterized in that: the process for making the laser mask layer comprises the following steps of: locally printing ultraviolet-cured gloss oil on the pictures and texts through a gravure printing device for carving a laser mask layer region range on a version roller; stamping laser masks on the ultraviolet-cured gloss oil by using a die pressing device; and curing the ultraviolet-cured gloss oil by using an ultraviolet curing device so as to obtain a local laser mask layer.

Description

technical field [0001] The invention relates to a special printing method, in particular to a method for making local laser lines on the surface of a printing material by a film printing transfer method. Background technique [0002] The film printing transfer method is currently a popular method in the printing and packaging industry to produce metallic graphics or non-graphics on the surface of printing materials. The steps are generally as follows: Oriented polypropylene film (OPP film) or polyethylene terephthalate Ester film (PET film) and other films→coat release layer on the film→print graphic on the release layer→coat embossed layer on graphic and mold embossing laser pattern→plate bright metal on the entire surface of laser pattern layer Color → apply glue on the bright metallic color layer → combine the glued side of the film with the printing material → peel off the top film → leave the bright metallic color layer and graphics on the printing material to achieve t...
