Digital discharge printing method

Abstract

The invention belongs to the field of printing and specifically relates to a digital discharge printing method which comprises the following steps: (1) preparing digital texbinder discharge white; (2)choosing color cloth which is dyed by reactive dye matched with the texbinder discharge white in the step (1); (3) performing counterpoint before printing; (4) starching slurry and color printing; (5) pressing or roasting. The digital discharge printing method disclosed by the invention comprises the technological processes: texbinder discharge white-color printing-airing-pressing/roasting, so that a step of reducing deep cloth into white is saved, and technological processes are simplified; meanwhile, a brightness degree of color printed and dyed on a printed material is high, and color fastness is strong; in addition, according to the digital discharge printing method disclosed by the invention, a screen plate locator is arranged on a silk printing screen plate, a location code clamp isarranged on a silk printing platform, a proximity sensor is arranged on a digital printing machine, a location work section of the silk printing screen plate in a printing process is simplified as that the screen plate locator and the location code clamp are tightly close to each other, location operation on the silk printing screen plate is simplified, and printing accuracy is improved.

Description

Technical field [0001] The invention belongs to the field of printing, and specifically relates to a digital dial printing method. Background technique [0002] In the process of dyeing and printing, the background dye of colored fabrics is destroyed by the function of whitening agent, so as to obtain partial achromatic or heterochromatic patterns. The former is called whitening and the latter is coloring. The printing advantage presented by pulp printing is irreplaceable by direct printing. The biggest advantage is that it can show light-colored patterns on dark and low-colored fabrics. In the printing industry, the commonly used dyeing and printing processes include paint dyeing and reducing fuel dyeing. It is a printing method in which reactive dyes are used to dye the base color and paint or reduced fuel is used to color. The hand feel and fastness of the dyed dyeing and printing process fabric are not ideal, while the reduced fuel dyeing and printing process is limited in t...
