Abstract

The invention belongs to the technical field of printing dyes in weaving, printing and dyeing industry, and concretely relates to a prepared active dye-based ink formula, preparation, and a color-separation printing method of using the dye-based ink formula to divide a pattern into CMYK four colors. According to the provided active dye-based ink formula, the ink is composed of an active dye, a thickening agent, a surfactant, a humectant, a bactericide, a pH buffering agent and deionized water. Additionally, the invention provides the preparation method of the ink and the application technology. Dye fixation is realized in a heat baking drying process after ink-jet printing, and the problem is overcome that color matching is difficult during large-scale four color separation printing after an ink-jet printed sample is confirmed.

Description

technical field [0001] The invention belongs to the technical field of printing dyes in the textile printing and dyeing industry, and specifically refers to the formulation and preparation of a reactive dye ink, and a color separation printing method for dividing patterns into CMYK four colors. Background technique [0002] The four-separation mode is a color registration mode used in color printing. It uses the color mixing principle of the three primary colors of the color material, plus black, and a total of four colors are mixed and superimposed to form the so-called "full-color printing". In the printing and dyeing industry, the digital printing technology, which has developed rapidly in recent years, is often used to make small samples in the production process due to its convenience and quickness, and does not require plate making. After the small sample is determined, it is then printed by roller or rotary screen printing Batch high-speed printing technology for prod...
