Color spray-painting process

Abstract

The invention discloses a color spray-painting process, which belongs to the technical field of pattern color spray painting, and comprises the following steps: a) printing a needed pattern layer on a base material of a multicolor pattern to be spray-painted by using a UV spray-painting device, wherein the pattern layer is a UV solidified coating layer; b) while spray-painting the pattern layer, performing UV solidification on the pattern layer, namely drying the pattern layer after the spray painting instantly, spraying a protective paint layer for the pattern layer after the spray painting and the UV solidification, and air drying the pattern layer naturally at the room temperature; and c) detecting a color spray-painting material finished by spraying. A spray-painting machine in the process manages inks with different colors separately and performs the spray painting with a plurality of spray heads so that colors are vivid; a negative pressure ink supply system is adopted to ensurethat the ink amount is stable during outputting; and the process supports ICC color management, can effectively control color changes caused by ink or medium differences, can really achieve accurate spray painting through X and Y bidirectional positioning, is more convenient for batch operations, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of pattern color inkjet printing, and in particular relates to a color inkjet process for color inkjet printing a pattern-containing UV photocurable coating. Background technique [0002] Some decorative panels with plastic and glass as carriers can be widely seen in daily life, and can be used as decorative items or children's toys, which are very versatile. At present, most of the patterns formed on this kind of decorative board are screen printing or pad printing technology. It is necessary to make the pattern to be transferred first and then make the film. The single-color printing can only be completed by making a stencil and other complicated processes, which cannot be realized. There is a need for multi-color and only plane construction; currently, to solve the problem of multi-color, it is basically to use multiple machines to print monochrome at the same time. This process is inefficient, and the pr...

Problems solved by technology

At present, most of the patterns formed on this kind of decorative board are screen printing or pad printing technology. It is necessary to make the pattern to be transferred first and then make the film. The single-color printing can only be completed by making a stencil and other complicated processes, which cannot be realized. There is a need for multi-color and only plane construction; currently, to solve the problem of multi-color, it is basically to use multiple machines to print monochrome at the same time. This process is inefficient, and the printed multi-color patterns often appear There are many ghost images and the yield rate is low, so it is difficult for real industrial application; at present, there is also a color inkjet process that injects multiple colors into the IMR film. This type of process takes a long time to develop and requires the development of precise molds. expensive
