Problems solved by technology

[0003] In the printing process of traditional paper packaging boxes, the image on the packaging box is printed at one time, and the printed image is relatively flat, the color separation in the image is more prominent, and the transition between images is relatively It is stiff and soft, which affects the simulation of the entire image. At the same time, the printed picture is too flat and has no three-dimensional effect. After using the packaging box for a long time, the image will fade seriously

Embodiment 1

[0055] A paper packaging box gravure printing process, comprising the following steps:

[0056] S1: Decompose the pattern to be printed according to the color level, and engrave the decomposed pattern on the printing roller with laser mirror image respectively. When performing laser mirror image engraving, determine the depth of the engraved pattern on the printing roller according to the ink thickness of the printed pattern , to complete the engraving of the printing roller; when decomposing the pattern, it can be decomposed according to the level or color of the pattern; when decomposing according to the color, it can be decomposed according to the similarity of its color, and the decomposed layers are based on 3-6 layers. The decomposed image of each layer is subjected to a stereotyped design, and the designed stereotyped pattern is respectively engraved on the printing roller that needs to be printed by laser. The depth of the engraved pattern on the printing roller is 15u-...

Embodiment 2

[0070] Such as figure 1 The gravure printing equipment for a paper packaging box shown includes:

[0071] The paper feeding assembly 1 sends the paper to be printed and stacked one by one into the printing assembly 3; the paper feeding assembly 1 includes a base 101, and the top of the base 101 is provided with a second conveyor belt 102, and the two conveyor belts 102 The side is provided with a baffle 103, and the paper placed on the base 101 is transported to the baffle 103 by the conveyor belt 2, and the paper is sent into the printing assembly 3 one by one by the baffle 103; There is a paper inlet 5 to ensure that the paper feeding assembly can feed paper into the printing assembly 3 through the paper inlet 5;

[0072] Several printing assemblies 3, the printing assemblies 3 are sequentially connected through the clamping mechanism 305 according to the printing order of the printing patterns, and the decomposed patterns of the paper entering the printing assemblies 3 are...

Embodiment 3

[0079] On the basis of embodiment 2, some of the printing components 3 and the oil layer printing components 10 are the same ink printing components;

[0080] This ink printing assembly comprises frame 301, and the bottom in this frame 301 is provided with ink tank 306, and this ink tank 306 communicates with the ink adding bucket 304 that frame 301 side is provided with; There is an ink roller 307, and the top of the ink roller 307 is provided with a platen roller 308 that is located on the same vertical plane with the central axis of the ink roller 307 and whose central axes are parallel to each other. The ink roller 307 and the platen roller 308 are rotating When rotating to the other side, the lower peripheral surface of the ink roller 307 is in contact with the ink in the ink tank 306; the prepared ink is added to the ink tank through the ink adding bucket, and the ink roller 307 is positioned at the front of the ink tank Above and in contact with the ink in the ink tank,...

Abstract

The invention discloses a gravure printing equipment for a paper packaging box. The equipment is carried out according to the following steps: decompose the pattern to be printed according to the color level, and engrave the decomposed patterns on the printing roller by laser mirror image respectively; Install on the corresponding printing components, and adjust the distance between the printing roller and the platen roller; ink configuration, printing, first drying, mimeograph, second drying, crimping and alignment; multiple images to be printed are layered Processing, printing is superimposed printing, superimposed printing improves the 3D effect of the image, and at the same time, the superimposed part undergoes color fusion, making the edge more blurred and soft, and improving the image effect after printing; the printing effect of the configured ink is good, the color and luster It is more uniform, has no peculiar smell during the production process, is more environmentally friendly, has a high degree of automation of production equipment, and high precision of crimping processing, which reduces the labor intensity of workers and improves production efficiency.

Description

technical field [0001] The invention relates to the technical field of packaging box printing, in particular to a paper packaging box gravure printing process and equipment thereof. Background technique [0002] Gravure printing is to make the entire surface of the printing plate be covered with ink, and then use a special scraping mechanism to remove the ink in the blank part, so that the ink only stays in the cells of the graphic part, and then under the action of greater pressure , transfer the ink to the surface of the substrate to obtain printed matter. Gravure printing belongs to direct printing. The graphic part of the printing plate is concave, and the degree of depression varies with the level of the image, and the blank part of the printing plate is raised and on the same plane. [0003] In the printing process of traditional paper packaging boxes, the image on the packaging box is printed at one time, and the printed image is relatively flat, the color separatio...
