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 ensure that 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.
