Special low-dry-fading wide-color-gamut fluorescent ink for 10-micron frequency modulation screen

Abstract

The invention relates to special low-dry-fading wide-color-gamut fluorescent ink for a 10-micron frequency modulation screen. The special wide-color-gamut fluorescent ink is four-colored ink composed of yellow ink, pinkish red ink, green ink and black ink; in a formula, vegetable oil type connecting materials with marks of SF-F003, SF-G010, SF-G017, SF-G020 and SF-G021, which are produced by Guangxi Senke Resin Co. Ltd., are adopted; the special wide-color-gamut fluorescent ink can relatively rapidly penetrate into a paper layer, so that an ink layer on a paper surface is fixed as the viscosity is increased; the difficulty that the fixation speed of commonly used environment-friendly vegetable oil type ink is low is overcome. Compared with the prior art, the vegetable oil type four-colored ink provided by the invention has zero or low dry fading; a dry fading value of the four-colored ink completely meets International Standards (smaller than or equal to 0.5). The four-colored ink is specially customized for realizing printing of the 10-micron frequency modulation screen, and all requirements on the ink by 10-micron frequency modulation screen printing are sufficiently met. The special wide-color-gamut fluorescent ink provided by the invention selects special color-phase pigments and fluorescent pigments, and a color gamut of the four-colored ink is widened.

Description

technical field [0001] The invention relates to the field of offset printing inks, in particular to a wide color gamut fluorescent ink specially used for low dry fade and 10 micron frequency modulation network. Background technique [0002] Green printing refers to the use of environmentally friendly materials and processes, the printing process produces less pollution, saves resources and energy, and is easy to recycle and recycle printed materials after they are discarded. It can be naturally degraded and has little impact on the ecological environment. Green printing requires coordination with the environment, including the use of environmentally friendly printing materials, a clean printing production process, the safety of printed materials for users, and the recycling and recycling of printed materials. That is to say, the entire life cycle of printed matter from raw material selection, production, use, recycling, etc. should meet environmental protection requirements....

AI Technical Summary

Problems solved by technology

So far, no one has integrated vegetable oil-based inks, zero or low dry-out inks, 10-micron FM special inks, wide color gamut inks, and fluorescent inks, which represent the highest level of ink development today, into the same set of high-end four-color inks. middle
