What Are The Classifications Of Digital Printing

Classification of digital printing

According to the printing method, it can be divided into digital direct printing, thermal transfer printing, and cold transfer printing.

Digital direct printing

The digital direct jet printing method is suitable for disperse, acid dyes, coatings, and reactive inks. The digital direct jet printing method is a process of direct jet printing on the semi-finished textiles that have been sized. The process is: select the corresponding ink according to the textile, Carry out pattern design, sizing, and then go to the textile direct spray printing machine for direct spray printing, and then dry, steam, wash, dry, soften and shape and other processes (the paint can be fixed by baking once)

Thermal transfer method

Thermal transfer printing is to print textile dyes onto paper (coated), and then use thermal transfer printing machine to transfer the patterns on the paper to textiles. The advantage is that the precision is relatively high, but the printing efficiency is low. It can only be made of full polyester or textiles with a relatively high polyester content. The transfer printing fabrics are all processed by semi-finished products without adding softeners (adding softeners may affect coloring rate).

cold transfer method

Like thermal transfer printing, it is necessary to print textile dyes on paper first, and then use special machinery to emboss the paper and fabric to realize the transfer of patterns.

There are 2 ways to process the embossed fabric:

One is to carry out traditional processing such as steaming, washing, and shaping;

The second is to carry out cold pile chemical reaction treatment to fix the color (the fabric needs to be chemically treated in advance).

Use reactive, disperse, acid and other dye inks, and this process is suitable for fabrics other than blended fabrics.
