Printing method with metal luster

Abstract

The invention relates to a new printing method with metal luster. The printing method comprises the steps: firstly designing and manufacturing a special 5-color goal color target, namely a CMYK+metal special color goal color target; printing the special 5-color goal color target manufactured in the previous step, so as to obtain a standard printing proof; collecting goal color target color information in the standard printing proof; manufacturing a 5-color goal ICC file applied to metal printing; carrying out color separation and color treatment on an image obtained by printing according to a metal printing method, so as to obtained a digital image file provided with 5-channel color information; printing, so as to obtaine a metal printing finished product. The printing method has the advantages of higher printing speed, high production efficiency, low cost, wide material selection range and elegant metal printing effect. The metal color can be adjusted accurately according to different requirements. The printing method has a great advantage compared with a traditional metal foil paper printing method.

Description

technical field [0001] The invention belongs to the field of printing industry, and specifically relates to a new metal texture printing method. Background technique [0002] Traditional metal printing methods are mostly realized by screen printing methods, which cannot meet the needs of the development of the times in terms of printing accuracy and efficiency. Traditional metal printing methods do not have ICC files for color separation and image adjustment, so accurate color preview and color separation cannot be performed before printing. In terms of color rendering, the metallic effect presented by the traditional offset metal printing method mainly depends on the actual color of the prepared metallic spot color. In terms of printing materials, the traditional four-color offset metal printing method, the printing material is metal foil paper, and the UV printing method is used to print four-color ink on the metal foil paper to achieve different metal effects.
