Embodiment Construction

[0025] The invention discloses a UV printing process for color packaging boxes, including the following steps:

[0026] (1) Take the box blank 10, use the first screen to print the color ink on the entire surface area of ​​the box blank 10, and use the UV lamp group to cure the printed color ink to form the background pattern layer 20; in this embodiment Among them, the color ink includes the following components by weight: 10-16 parts of acrylate oligomer, 50-80 parts of diluent, 5-10 parts of photoinitiator, 10-15 parts of color pigment, wetting fluid 0.8-1.5 parts of flat defoaming agent; 0.5-0.8 parts of polymerization inhibitor, and the acrylate oligomer is a polyacrylate with side chain carboxyl group, and the diluent is difunctional hexane with extremely low absolute viscosity. Diol diacrylate, the photoinitiator is a photoinitiator whose absorption peak is close to the absorption trough of the pigment, and the blue UV color ink uses a free radical cracking type photoin...

Abstract

The invention discloses a UV printing process for a color packaging box. The process comprises the following steps: (1) taking a box blank, printing color ink on the whole surface area of the box blank by using a first screen plate, and curing the printed color ink by using a UV lamp set to form a background pattern layer; (2) performing UV transparent gloss oil printing on the surface local areaof the background pattern layer by using a second screen plate to form a UV gloss oil bottom layer, wherein the thickness of the UV gloss oil bottom layer is not less than that of the background pattern layer; and (3) spraying colored microspheres on the surface of the UV gloss oil bottom layer before the UV gloss oil bottom layer is not cured. The UV gloss oil bottom layer is printed on the background pattern layer, and the colored microspheres are sprayed on the surface of the UV gloss oil bottom layer, so that a surface pattern layer is formed, the surface pattern layer is made to float onthe background pattern layer, a better three-dimensional effect is achieved, and the product is more beautiful and elegant in appearance.

Description

technical field [0001] The invention relates to the technology in the field of printing, in particular to a UV printing process for color packaging boxes. Background technique [0002] With the progress of society and the improvement of aesthetics, people have higher and higher requirements for printed products. In order to beautify the packaging, the printing color should not only be smooth and colorful, but also need more advanced glass and metal luster, and also have a three-dimensional effect to show its magnificence and nobility. [0003] At present, the production of color packaging boxes mainly adopts UV printing process. The UV printing process in the prior art simply prints a variety of color inks on the surface of the packaging box, which cannot make the pattern float, and the three-dimensional effect is not good. Therefore, it is necessary to study a scheme to solve the above problems. Contents of the invention [0004] In view of this, the present invention a...
