What do we do with screen printing?
Advantages of screen printing mesh: (1) It is not limited by the size and shape of the substrate. It can only be printed on a flat surface. The screen printing can not only print on a flat surface but also on a special shaped molding such as a spherical surface. Printed on the surface, shapes can be done by screen printing. (2) The soft and small screen of the screen is soft and flexible. (3) The ink layer has strong covering power and can be printed on pure black paper with strong three-dimensional effect. (4) Applicable to all types of inks (5) Strong anti-rotation performance can make the gloss of printed matter unchanged. (No effect on temperature or daylight). This allows for the printing of some stickers without the need for additional filming and other processes. (6) Flexible printing method (7) Easy plate making, cheap price, easy to master technology (8) Strong adhesion (9) Can be hand-printed by silk screen, or machine-printed (10) Suitable for long-term display, rich in outdoor advertising Expressiveness.
1. It is not limited by the size and shape of the substrate. Generally, the printing can only be carried out on a flat surface, and the silk screen printing can not only print on a flat surface, but also print on a special shape of the molded object and the uneven surface, and can also print various kinds. Very large advertising paintings, curtains and curtains. For example, at present, the printing area of general offset printing, embossing and the like can print a maximum size of a full sheet, which exceeds the full sheet size and is limited by mechanical equipment. Screen printing can be used for large-area printing, with a maximum format of up to 3m x 4m or even larger. It can also be printed on ultra-small, ultra-high-precision items, and can also be printed on curved or spherical surfaces. This printing method has great flexibility and wide applicability. All shapes and shapes can be printed with silk screen. Screen printing is also possible for those special surfaces.
2, the layout is soft and small
Screen printing is soft and flexible, and has a small printing pressure. Therefore, it can be printed on soft substrates such as paper and textiles, and can be printed on various types of glass and ceramic ware that are easily damaged by pressure.
3, the ink layer is thick and strong
The thickness of the ink on the relief and slab prints is only a few microns, the gravure printing is only 12-15 microns, and the thickness of the screen printing ink can reach 30~100 microns. Therefore, the hiding power of the ink is particularly strong, and it can be used in all black paper. Printed on pure white for printing. In addition, printing such as circuit boards and oil paintings can be performed using the characteristics of ink thickness. Braille lettering printed with foaming ink, the thickness of the ink layer after foaming can reach 300 microns.
The screen printing ink layer is thick, and the printed graphic has a strong three-dimensional effect, which is unmatched by other printing methods. If the printing method of one moving is to cover the underlying color with white, it is necessary to copy the same part 3~4 times, and the screen printing can be completed once. Since the thickness of the ink layer is good and the three-dimensional feeling is good, the application is very wide. Of course, the thickness of the ink layer can also be controlled.
4, for all types of ink
Screen printing has the characteristics that it can be printed using any kind of paint, such as oil, water, synthetic resin, powder and the like can be used. Screen printing inks are actually various coatings. Other printing requires that the pigments of various inks be finer, and that screen printing can be used as long as inks and coatings that can pass through the mesh mesh fineness. Screen printing can not only print monochrome, but also color printing and screen printing for color printing.
The wide range of inks used in silk screen printing has gone beyond the definition of conventional inks. In fact, there are pastes, pastes, paints, adhesives or solid powders. Therefore, screen printing inks are sometimes referred to as "printing materials".
5, strong light resistance
Since screen printing can print a thick ink layer, various binders and various colorants can be used, and even coarser pigments can be used, so that he can put light-resistant pigments and fluorescent pigments in a simple manner. Into the ink, so that the graphic of the printed matter is permanently kept from the influence of temperature and sunlight, and can even be illuminated at night. Screen printing inks are easy to mix, for example, light-resistant pigments can be placed directly into the ink. Because silk screen products have strong light resistance, they can be used for advertising and signage outdoors.
6, flexible printing methods
Screen printing, like flat, concave, and convex printing, can be industrially produced on a large scale. At the same time, it has the advantages of flat, concave and convex printing, which is incomparable in plate making, low in price, flexible in printing method, flexible in technology and easy to grasp in technology, so it has developed rapidly in recent years. It is not limited by the size of the enterprise. It can be produced by industrial mechanization, and it can also be produced by township enterprises and individual handicrafts.
