Double-color gradual-change printing technology of aluminum aerosol can

Abstract

The invention discloses a double-color gradual-change printing technology of an aluminum aerosol can. The technology comprises the following steps that ink isolation is carried out, wherein a single ink tank is used, and the two kinds of ink are separated from each other by using an ink separating device in the ink tank, so that mixing of the two kinds of ink is avoided; color mixing is carried out, wherein a single printing plate is prepared, the two kinds of printing ink are subjected to color mixing by utilizing an ink transferring rubber roller, and then are printed on the same printing plate, so that the uniform transition of the two kinds of ink is realized; and printing is carried out, wherein surface printing is carried out on the aluminum aerosol can by using the single printing plate, and the aluminum aerosol can is rolled by one circle to obtain a double-color gradual-change printing pattern. By means of the mode, the double-color gradual-change printing technology of the aluminum aerosol can can be completed through the single printing plate, so that the cost is reduced, the problem of screen dot interference caused by two printing plates is solved, and the printing quality is ensured; and the position of the surface gradual change area of the aluminum aerosol can can be adjusted by adjusting the position of an sub-ink transferring rubber roller.

Description

technical field [0001] The invention relates to the technical field of aluminum can production, in particular to a two-color gradient printing process for an aluminum aerosol can. Background technique [0002] The traditional two-color gradient effect of aluminum cans is achieved by dot overprinting on two gradient printing plates during the printing plate making process, but the gradient effect obtained by this kind of dot overprinting has the following defects: [0003] 1. The gradient effect is not ideal, and there will be a mesh structure in the gradient overprinting part. If the overprint is not accurate, it will easily cause dot interference, and a thicker grid will appear, which will affect the appearance; [0004] 2. The position of the gradient area cannot be adjusted during the production process. If you want to change the position of the gradient area, you can only remake the printing plate, which is a waste of plate materials; [0005] 3. The overprinted part in...

Problems solved by technology

[0003] 1. The gradient effect is not ideal, and there will be a mesh structure in the gradient overprinting part. If the overprint is not accurate, it will easily cause dot interference, and a thicker grid will appear, which will affect the appearance;

[0004] 2. The position of the gradient area cannot be adjusted during the production process. If you want to change the position of the gradient area, you can only remake the printing plate, which is a waste of plate materials;

[0005] 3. The overprinted part in the gradient area will have obvious ink bleeding after a period of production, which will cause the color of the gradient part to change color if you don't pay attention to it during mass production, resulting in the scrapping of the product and needs to be improved.
