What are the characteristics of non-woven screen printing?


The non-woven bag screen printing process, which is often referred to as "silk printing", screen printing refers to the use of silk screen as the plate base, and through the photosensitive plate making method, made into a screen printing plate with pictures and texts. Screen printing consists of five major elements, screen printing plate, squeegee, ink, printing table and substrate. Use the basic principle that the mesh of the graphic part of the screen printing plate can penetrate the ink, and the mesh of the non-graphic part cannot penetrate the ink for printing. When printing, pour ink on one end of the screen printing plate, use a squeegee to apply a certain pressure to the ink part on the screen printing plate, and at the same time move to the other end of the screen printing plate at a uniform speed, the ink is moved by the scraper from the graphics and text Part of the mesh is squeezed onto the non-woven fabric.

Non-woven bag screen printing is a common and commonly used printing method in bag printing. First, the film is made according to the customer's design files such as CDR or AI format files, and then the film is stretched. Because the color of the screen printing is one color It is printed in one color, so the more colors of the silk screen, the more sheets of film will be produced. Mainly have the following five characteristics:

1. It is not limited by the size and shape of the substrate: general printing can only be performed on a flat surface, and silk screen printing can not only print on a flat surface, but also print on a special shape and a concave-convex surface. Print all kinds of super large posters, curtains and curtains.

2. The layout is soft and the printing pressure is small: The screen printing plate is soft and flexible, and the printing pressure is small, so it can not only print on soft substrates such as paper and textiles, but also on glass and ceramic vessels that are easily damaged by pressure. Print it.

3. Thick ink layer and strong covering power: The ink thickness of screen printing can reach 30μm-100μm. Therefore, the covering power of the ink is particularly strong, and it can be used for pure white printing on all black paper. The ink layer of screen printing is thick, and the printed images and texts have a strong three-dimensional effect, which is incomparable to other printing methods.

4. Applicable to various types of inks: The wide range of inks used in silk screen printing has exceeded the definition of ordinary inks. In fact, there are pastes, plastics, paints, adhesives or solid powders. Therefore, screen printing inks are sometimes collectively referred to as "printing materials."

5. Strong light resistance: In general, the classification of inks should be classified according to the printing plate type, that is, it can be divided into letterpress ink, lithographic ink, intaglio ink and filter ink. However, this classification is too principled and cannot express all the reality. In recent years, due to the continuous increase of ink varieties and the continuous emergence of new designs, it is limited only by the type of printing.
