Textile Printing Process Is Critical To Screen Printing.

The pattern design, the black and white color separation manuscript (namely the Yang piece), generally adopts the continuous shooting technology photoreceptor plate, in addition to the independent flower shape, mainly by the manual operation primarily, to the worker technical quality request is high, the work efficiency is low.

Photosensitive materials for making plates need to be water-resistant.

The pattern is usually done by photography or scanning. Most of the colors are made of four colors. The printed patterns are mostly independent. There is no printing process. The photosensitive materials are mostly solvent resistant.

< p > it is the main material of screen printing. The silk screen woven with silk has long been replaced by nylon screen. Although nylon mesh has high strength, wearability and elasticity, it is easy to be influenced by temperature and humidity. It has large flexibility and affects the accuracy of the layout. Therefore, polyester (polyester) screen is widely used when printing high-grade products.

There are also metal screens, such as nickel screen for rotary screen printing and stainless steel wire mesh for circuit boards.

There are a wide variety of specifications, with a width of 36~90 inches and a mesh of 80-500 mesh / inch, which can be selected for different purposes.

< p > screen printing equipment is very complex. There is a big gap from simple household workshops to modern complete sets of equipment. Here we can only briefly distinguish them.

< /p >

< p > textile screen printing is divided into circular net and peace net. The flat screen equipment has printing platen, automatic flat screen printing machine and rotary disc printing machine.

The automatic flat screen machine has a maximum width of 3.2m, a length of about 60m, and a maximum color of 12 colors. It belongs to large equipment. Textile screen printing is usually continuous printing. Even handkerchiefs and tablecloths with independent patterns are cut out after continuous printing.

In general, there are desktop manual, semi-automatic, automatic flat screen printing machines and drum type, curved surface, three-dimensional printing press, etc., and most of the special equipment is available, and the gap of printing area is also very large. Their common characteristics are mainly independent printing methods (i.e., one workpiece and one workpiece individually printed).

< p > simply say there is a difference between water and solvent (commonly known as oil).

< p > textile printing is generally based on dyes, especially on silk fabrics, and the corresponding dyes should be used according to different fiber properties.

Technical process and supporting equipment are more complex. Printing pigment printing paste is used as printing material. Some people call it "water-based ink".

Because of the need of practicality, the color of textile screen printing must have a certain degree of firmness (not easy to fade), and at the same time, its color changes greatly. Therefore, slurry and pigment should be sold and stored separately.

In addition, there are many special functional pigment printing paste, which is often not restricted by fabric properties. Therefore, screen printing has a certain position.

< p > non textile screen printing ink.

This type of ink is almost solvent, and its biggest feature is "specificity", that is, what materials to use to print what ink; secondly, the color of the ink is mostly sold with finished products, such as four-color ink.

There are also some special functional inks, such as foamed ink, bright ink, fluorescent ink and so on.

In recent years, the variety of screen printing ink is increasing.

< p > textile screen printing process, < a href= "http://cailiao.sjfzxm.com/" > post-processing < /a > is very important. It must be dyed by high temperature steaming or drying to make dye and textile fiber combined to ensure color fastness.

After fixing, it should be washed to remove the carrier and unfixed dye in the printing paste, so that the color will be bright.

Even if the coating process is applied to high temperature, it can not be washed.

The post processing of non textile screen printing is generally relatively simple. However, it is necessary to take some necessary treatment in accordance with the quality requirements of printed products, such as UV curing of UV ink.
