Problems solved by technology

But digital color printing is only suitable for a small amount of printing, and the cost is high
Since the color gamut of digital color matching is larger than that of gravure printing (CMYK mode, C is Cyan, M is Magenta, Y is Yellow, and K is black), the raw materials such as ink and paper of digital samples are different from those of gravure printing. The raw materials used in gravure printing are different, and there are many uncertain factors affecting the matching degree between the two color gamuts, which is difficult to control

Embodiment Construction

[0019] The implementation of the present invention will be described in detail below in conjunction with specific examples. It should be understood that the implementation of the present invention is not limited to the following examples, and any modifications and / or changes made to the present invention will fall within the protection scope of the present invention.

[0020] A digital color inkjet color matching process technology for gravure printing. Digital color inkjet printing provides color samples for gravure printing. pre-match.

[0021] Color pre-matching steps include:

[0022] (1) Obtain the color sample of the gravure printing machine; use the digital printer to print out the ICC swatch of the printer in CMYK color mode; compare the color of the ICC swatch of the printer with the color sample of the printing machine;

[0023] (2) According to the color difference between the printer's ICC swatch and the printing machine's color sample, adjust the ratio and ink v...

Abstract

The invention discloses a digital color-spray color matching technique used for intaglio printing. A color manuscript is provided for intaglio printing through digital color-spray printing. Color pre-matching is conducted on a digital printer and a photogravure press before the color manuscript is printed through digital color-spray. By means of the digital color-spray color matching technique used for intaglio printing, the time for developing a new color can be greatly shortened, the success rate of new color designing and platemaking is increased, the printing effect is guaranteed, the waste of printing rollers is reduced, and the development cost is substantially reduced.

Description

technical field [0001] The invention relates to a digital color jet color matching process technology for gravure printing, which belongs to the field of digital printing. Background technique [0002] Traditional gravure printing needs to engrave the plate roller first in the early design and color development, the cost of plate making and the risk of failure are high, and the process of color matching, sample, and color confirmation consumes a lot of ink, paper, and energy. It is necessary to repeatedly adjust the ink formula until the final color is confirmed. The input of manpower and material resources is large, the test process takes a long time, and the efficiency is low. [0003] With the continuous development of science and technology in the printing industry, digital color printing technology has developed rapidly in recent years. The digital color inkjet technology realizes the printing in the true sense, no need for plate making, and full-color images can be co...
