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 L7.0 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 89.5a -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 56.0a -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 Image 6 It can be seen that the blue line represents the ISO12647-2 (2013) standard color gamut; the red line represents the color gamut of the ISO12647-2 (2013) standard printed sheet after the matte film is covered; the yellow line represents the color of the Multicolor printed sheet after the matte film is covered Gamut; From the co...

Abstract

The invention discloses a method for improving a processing effect of a surface coated with a paper matte lamination film. The method is characterized in that the method comprises the following stepsof: (1) improving saturability: improving each primary color target value of a printed sheet before surface processing; (2) improving a contrast ratio; (3) improving definition; and (4) improving details. Black, blue, red and yellow color target values are changed to realize a purpose of improving the saturability, a lattice point enlargement target value is changed to realize contrast ratio regulation, a higher reticle adding number is adopted to realize a purpose of improving the definition, high-concentration ink is used to improve details, so that after a printed matter is coated with a matte adhesive film, integral color saturability is effectively improved, and a visual effect is exquisite, 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...
