Printing process design is mainly based on pattern characteristics and guest requirements. First of all, the pattern should be examined and determined according to factors such as fabric fiber, printing method, dye selection and equipment. Be sure to find out the guest's requirements for fabrics, such as polyester, cotton or blended fabrics. Secondly, make sure the guest's choice of printing dye. Direct dyes, reactive dyes or paints are generally used for cotton printing, disperse dyes for polyester and paints are also useful, but reactive dyes cannot be used.

The digital printing fabric can be printed on paper first and then transferred to cloth, while pure digital fabrics cannot be printed on horse cloth in general. The transfer is large in batch and can print 1.5 to 3 meters wide horse cloth. As for the discrimination, it can be seen how many critical lines of flower positions and color sets there are, and more than 8 transfers are not common. Therefore, if the colors are multiple and the levels are varied, it is very likely to be transferred.

Digital printing fabrics are usually designed by computer and finished by machine spray painting.

The transfer printing fabric usually prints the pattern on a medium first, and then heats it when printing.

One of textile printing methods. It began in the late 1960s. A printing method in which a certain dye is first printed on paper and other materials, and then patterns are transferred to fabrics by hot pressing. It is mainly used for printing chemical fiber knitwear and clothing. Transfer printing is processed by dye sublimation, migration, melting and stripping of ink layer.

Then, dure transfer printing, dye in that pattern is transfer to the textile by heat treatment and fixed to form the pattern. The most widely used transfer printing method is to use disperse dyes for dry transfer on synthetic fiber fabrics. The method comprises the following steps of: firstly, selecting suitable disperse dyes, solvents such as paste powder, alcohol, benzene and the like, grinding with resin to prepare ink, and printing on tough paper to prepare the transfer paper. During printing, the patterned side of the transfer paper is overlapped with the fabric, and after hot pressing at high temperature (220 degrees) for about 1min, the disperse dye sublimates into a gaseous state and is transferred from the paper to the fabric. No washing treatment is required after printing, thus no sewage is generated, and the effects of bright colors, clear layers and delicate flower shapes can be obtained. However, there are ecological problems, besides dyes and auxiliaries in color paste, a large amount of transfer paper is needed, which is difficult to recycle after printing.
