Embodiment 1

[0032] The invention provides a printing process for forming a multi-layer three-dimensional pattern by prism refraction. The specific printing steps are as follows:

[0033] Step 1: Put the base material of the base material into a hot pressing mold to produce a transparent plastic film with prism bumps on the front;

[0034] Step 2: According to the pattern to be printed, use a CTP direct plate-making machine for plate making;

[0035] Step 3: Put the sample plate obtained in step 2 into the UV printer, and then use the UV printer to print the back of the transparent plastic film with prism bumps on the front made in step 1. The UV printer uses water-based The UV ink is used for three-layer composite printing to obtain a plastic film with multi-layer three-dimensional patterns formed by prism refraction.

[0036] In step one, the prism bumps are hemispherical bumps, the height of the prism bumps is smaller than the spherical radius of the prism bumps, and the distance between...

Embodiment 2

[0049] Different from Example 1, the water-based UV ink includes: 56.50% water-based UV resin, 9.20% photoinitiator, 4.80% anti-aging agent A, 4.90% anti-aging agent B, 24.60% by weight percentage. % active diluent; the anti-aging agent A includes by weight percentage: 19.60% zinc acetate, 15.80% cellulose nanofibers, 64.60% polyvinylpyrrolidone; the anti-aging agent B includes by weight percentage : 33.50% silver nitrate, 46.80% resveratrol, 5.80% sodium hydroxide, 13.90% glass fiber.

Embodiment 3

[0051] All different from Examples 1-2, the water-based UV ink includes: 55.90% water-based UV resin, 8.85% photoinitiator, 4.20% anti-aging agent A, 4.50% anti-aging agent B, 26.55% reactive diluent; the antiaging agent A includes: 19.00% zinc acetate, 15.50% cellulose nanofibers, 65.50% polyvinylpyrrolidone; the antiaging agent B is calculated by weight The percentage calculation includes: 32.90% silver nitrate, 46.05% resveratrol, 5.20% sodium hydroxide, 15.85% glass fiber.

[0052] Get respectively the printing process in the above-mentioned embodiment 1-3 and the printing process of the matching group one, the printing process of the matching group two, the printing process of the matching group three, the printing process of the matching group four and the printing process of the matching group five, the matching group The printing process of one does not have zinc acetate in water-based UV ink compared with embodiment; The printing process of control group two does not ...

Abstract

The invention discloses a printing process for forming a multi-layer three-dimensional pattern through prism refraction, and particularly relates to the technical field of printing processes. In the first step, a transparent plastic film with prism salient points on the front face is manufactured, so that the effect of three-dimensional patterns on the film is better, different three-dimensional images can be seen when the printed patterns are seen from different angles due to the refraction effect of a prism, and the three-dimensional effect is better; and in the third step, a UV printer is used for printing treatment, water-based UV ink a is used for first-layer printing treatment, water-based UV ink b is used for second-layer printing treatment, water-based UV ink c is used for third-layer printing treatment, the antibacterial property, ultraviolet resistance, fast ion diffusion and high temperature resistance of a first layer printing film, a second layer printing film and a third layer printing film can be effectively enhanced, then the anti-aging property of a printed product is enhanced, and the problems of yellowing and falling are not prone to occurring under the action of long-time strong sunlight.

Description

technical field [0001] The invention relates to the technical field of printing technology, more specifically, the invention relates to a printing technology for forming multi-layer three-dimensional patterns by refraction of prisms. Background technique [0002] In the packaging industry, the transparent plastic box has a unique advantage of transparency, good corrosion resistance, acid and alkali resistance, impact resistance, and high mechanical strength, which can protect the product very well. At the same time, the transparent plastic box allows consumers to directly see the products inside, so that the product can be better displayed in front of customers, and can leave a deeper image for customers; transparent plastic boxes are used in food packaging, pharmaceutical packaging, promotional printing products, It is widely used in other printing and packaging industries. The transparent plastic box is mainly made of transparent film after cutting, folding and packaging....
