Embodiment

[0040] A digital dial printing printing method, comprising the steps of:

[0041] Step (1): Prepare digital pulp

[0042] The digital bleaching pulp includes the following raw materials: nano zinc oxide, sodium hypochlorite, powdered sodium polyacrylate and deionized water, the weight ratio of the nano zinc oxide to sodium hypochlorite is 1:3 to 1:58, the described The weight ratio of sodium polyacrylate to nano-zinc oxide is 1:1-1:0.5, and the amount of deionized water is 10-30% of the total weight of the solid;

[0043] Step (2): Fabric selection

[0044] Select the color cloth that the reactive dye that matches with the bleaching pulp of step (1) has been dyed;

[0045] Step (3): Pre-press alignment

[0046] The device used for pre-press alignment is the automatic positioning device of the digital printing machine (such as Figure 1-11As shown), the automatic positioning device includes a silk screen platform 30, a screen printing screen 40 and a digital printing machin...

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 in particular relates to a digital dial printing printing method. Background technique [0002] During dial dyeing and printing, the base color dye of the colored fabric is destroyed by the action of the whitening agent, so as to obtain a partially achromatic or different-color pattern. The former is called whitening, and the latter is color dialing. The printing advantages presented by pulp printing cannot be replaced by direct printing. The biggest advantage is that it can show light-colored patterns on dark and low-color fabrics. In the printing industry, the commonly used dyeing printing processes include paint dyeing and reduced 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 for coloring. The feel and fastness of fabrics in pigment dyeing and printing are not ideal, while the process of reducing dyeing dyeing is not c...
