Disperse dye ink group

Abstract

The invention provides a disperse dye ink group which comprises cyan ink, magenta ink, yellow ink and black ink, and the cyan ink, the magenta ink, the yellow ink and the black ink are sequentially subjected to jet printing in the printing advancing direction of a printing medium. The surface tension of any color of ink in the disperse dye ink group respectively meets 31.0 mN / m-39.0 mN / m; the surface tension of the cyan ink, the surface tension of the magenta ink, the surface tension of the yellow ink and the surface tension of the black meet the following relation: sigma cyan > sigma magenta > sigma yellow, and sigma yellow is approximately equal to sigma black; by the adoption of the scheme, after the front jet printing ink is printed to the printing medium, when the printing medium reaches the maximum value of the ink absorption amount of the printing medium, the rear jet printing ink can permeate into the front jet printing ink layer in the longitudinal direction, and therefore the phenomenon that the rear jet printing ink diffuses towards the periphery and is further dissolved in the print range, and the permeation phenomenon occurs is avoided; and the printing fineness of the ink is ensured.

Description

technical field [0001] The invention relates to the field of printing ink, in particular to a disperse dye ink set. Background technique [0002] When a desktop printer is performing color printing, the printer usually first recognizes the shape and color of the input pattern, then sends the pattern information to the processor to make a judgment, and then the processor outputs a series of operating instructions to control the printer nozzle to eject four-color ink , forming corresponding patterns and colors on the medium. [0003] When the disperse dye ink is printed on the printing paper by the desktop printer, the inks of various colors are superimposed on the printing paper before the printing pattern is dried, but because the disperse dye is dispersed in the water-soluble solvent in the form of particles, the ink will remain on the printing paper. There are stacks of dye particles. When the amount of ink is large, it is easy to see the problem that the ink superimposed...

Problems solved by technology

[0003] When the disperse dye ink is printed on the printing paper by the desktop printer, the inks of various colors are superimposed on the printing paper before the printing pattern is dried, but because the disperse dye is dispersed in the water-soluble solvent in the form of particles, the ink will remain on the printing paper. There are stacks of dye particles. When the amount of ink is large, it is easy to see the problem that the ink superimposed on the back will bleed at the edge of the imprint, making the ink further melt within the imprinting range, exceeding the limit of the imprinting application, resulting in the printing accuracy of the printed pattern. Poor, unsatisfactory print quality cannot be obtained
