Problems solved by technology

[0004] At present, the types of digital printing include cotton, wool, chemical fiber and other types of fabrics, and there are also a small amount of silk and other fabrics. Due to the characteristics of real silk, its surface is relatively smooth. Insufficient accuracy and fidelity, the quality of printed products is low; especially for light-colored printing, due to the influence of temperature, ink batch and other factors, color difference often occurs, and some can even be observed with the naked eye, affecting product quality

Abstract

The invention relates to a low-color-difference digital printing technique which comprises the following steps: pretreatment, drying, ink-jet printing, drying, warm water washing, soaping, warm water cleaning and drying. By adopting the special ink formula, the dyeing effect of the reactive dye is greatly enhanced. The technique is used for true silk surface printing, and has the advantages of bright color, high color fastness and low color difference.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a digital printing process with low color difference. Background technique [0002] Digital inkjet printing technology is a great expansion of inkjet printing in the field of industrial applications. When modern computer inkjet printing technology is used for textile printing, various input means such as scanners, digital cameras, digital cameras, etc. can be used to digitally input the required patterns into the computer, and then processed by various graphics software printing color separation systems. Finally, through a computer-controlled digital inkjet printing machine, the printing ink is directly sprayed onto various fiber fabrics to print various patterns required. This printing technology is called digital inkjet printing. [0003] In recent years, digital printing technology has developed rapidly. Compared with traditional printing, digital printing has a cle...
