Screen printing and screen printing machine

Screen printing is a type of hole printing. Screen printing involves stretching a mesh of fabric over a screen frame and making a plate for printing.Hole plate printing includes hollowed-out plate, transcribing plate, spray plate and clamping antagonistic printing method. Clamping antagonistic printing method is screen printing. Screen printing method is most widely used in hole plate printing industry.Compared with other printing methods, screen printing is outstanding in the following aspects:

(1) Strong adaptability.Gravure, embossing, lithography can only be printed on a flat substrate.However, in addition to the screen printing can be printed on the surface of the plane substrate, but also in the sphere, curved surface and concave-convex surface and other special shape surface can be printed.Usually, according to the different substrate, can be divided into: paper, plastic, glass, ceramics, metal, circuit board, textile and other categories, also formed their own printing system.

(2) Thick ink layer, texture and three-dimensional sense of strong.In lithography, gravure and embossing three printing methods, ink layer thickness is only about 12 microns.Relatively speaking, screen printing can generally reach the ink layer thickness of about 30 microns, far more than the above methods.Ink layer thick, texture and three-dimensional strong, other printing methods can not meet.

(3) Strong optical rotation resistance and constant luster.Omission, screen printing is a major feature, so in the printing can use a variety of characteristics of ink and paint, the same pigment particle size is not too strict requirements.In addition, screen printing ink allocation method is simple.It has been proved by practice that the density range of one printing on coated paper by screen printing is 0.5-2.0, so screen printing products have strong light resistance and can be widely used in outdoor advertising and signage fields.

(4) Large printing area.Screen printing can be as large as 3 m X4 m or larger.The reason for this situation is that due to the limitation of mechanical equipment size, it is difficult for other printing methods to exceed the full sheet size. However, screen printing can avoid this limitation and carry out super large area printing.Combined with the use of screen printing in real life, there are various types of printing machines and screen printing methods.Screen printing mainly USES two printing methods, plane printing and surface printing. As far as the domestic market is concerned, the flat screen screen printing machine occupies almost all the market share.
