Embodiment Construction

[0035] The invention discloses a method for improving the surface treatment effect of coated paper dumb coating, which comprises the following steps:

[0036](1) Improve saturation: increase the target value of each primary color of the printed sheet before surface treatment; the color target data is as follows: Black L 7.0 a 0.0 b 0.0 Blue L 48.0 a -31.0 b -60.0 Red L 45.0 a 85.0 b 4.0 Yellow L 89.5 a -3.0 b 120; ISO 12647-2 2013 target data are as follows: Black L 16.0 a 0.1 b -0.3 Blue L 56.0 a-34.9 b -52.5 Red L 48.1 a 75.3 b -5.2 Yellow L 88.9 a -4.0 b 92.4. The actual printed sheet effect comparison is as follows Figure 5 shown, and from Figure 6 It can be seen that the blue line indicates the ISO12647-2 2013 standard color gamut; the red line indicates the color gamut of the ISO12647-2 (2013) standard printed sheet after the matte film is coated; the yellow line indicates the color gamut of the Multicolor printed sheet after the matte film is coated; From the color ...

Abstract

The invention discloses a method for improving the surface treatment effect of coated paper dumb coating, which is characterized in that it includes the following steps: (1) improving saturation: increasing the target value of each primary color of the printed sheet before surface treatment; (2) improving Contrast; (3) Improve sharpness; (4) Improve detail. By changing the color target values ​​of black, blue, red, and yellow, the saturation can be improved; by changing the dot gain target value, the contrast can be adjusted; by using higher screen rulings, the sharpness can be improved. And by using a higher concentration of ink to improve the details, so that the overall color saturation of the printed matter is effectively improved after the matte film is covered, and the visual effect is delicate, bright and clear.

Description

technical field [0001] The invention relates to the technology in the field of printing, in particular to a method for improving the surface treatment effect of coated paper matte film. Background technique [0002] Undoubtedly, ISO 12647-2 "Printing Technology - Process Control of Halftone Color Separations, Samples and Printed Products Part 2: Offset Printing" is the most widely used offset printing process standard for printing companies. This standard is a powerful basis for evaluation and correction of printing standardization. With it, printing standardization and process control can be carried out effectively. The standard was promulgated in 1996 and revised once in 2004 and 2013 respectively. At present, most of the ISO12647-2 standards implemented by printing companies in offset printing production are version 2004, and there are some gaps between this standard and the current actual printing conditions. Therefore, it is necessary for printing companies to carry ou...
