What is silk screen printing technology?There is a kind of printing technology adopts the method of hand carved film or photochemical process the silk, synthetic fiber fabric or metal wire mesh screen stretched on the net box printing plate, this printing is silk screen printing technology.Screen printing technology in the most widely used in printing.

      So, what's the difference between silk screen printing and other printing?Compared with other printing, silk screen printing technology has four features:

1, strong adaptability,

      Flat printing, letterpress and gravure printing method normally only for printing on flat substrates.Can not only in the plane printing and silk screen printing, can also be curved surface, spherical and concave and convex surface printing on substrates.On the other hand, silk screen printing not only in hard surface printing, also can be printed on the soft material, not restricted by the quality of a material of substrates.In addition, screen printing in addition to direct printing, can also according to the need to adopt indirect printing method, namely with silk screen printing on the gelatin or silicone version first, and then transfer to the substrates.Therefore screen printing adaptability is very strong, wide range of applications.

2, large printing area

      At present the general offset printing, letterpress printing methods, such as the printing area size sheet size, maximum exceed sheet size, is subject to the conditions of mechanical equipment.Can undertake large printing and silk screen printing, today's biggest screen printing products up to 3 m * 4 m, is even greater.

3, strong light fastness

     Bright color because the silk screen printing has the characteristics of the bearing, so it can be used to all kinds of printing ink and coating, not only can use the slurry, bonding agent and various kinds of pigments, also can use coarser particles of paint.In addition, screen printing ink mixing method is simple, for example, can put the light paint directly into the ink mixing, this is the another big characteristic of silk screen printing.Screen printing products with strong light fastness of great advantage.The practice shows that by using the black ink in coated paper last impression after comparing measured maximum density range, offset printing is 1.4, embossed 1.6, 1.8, gravure and screen printing of maximum density range can be up to 2.0, so the light fastness of silk screen printing products than other kinds of printing products of light fastness is strong, more suitable for the outdoor advertising, signs.

    4, ink layer thick, stereo sense is strong

     Rich texture letterpress and offset printing ink layer thickness is commonly 5 microns, gravure of 12 microns, flexible printed version (aniline) ink film thickness of 10 microns, and silk screen printing ink layer thickness is far more than the ink layer thickness, generally up to 30 microns.Special printed circuit board with thick silk screen printing, ink layer thickness to 1000 microns.Foam with foam ink printing braille point yu, ink layer thickness is 1300 microns.Silk screen printing ink layer thick, print rich simple sense, stereo sense is strong, this is other printing method can not be compared.Not only can screen printing monochrome printing, also can undertake chromaticity and color printing.

     Above is the difference between silk screen printing and other printing, as well as the characteristics and advantages of screen printing.Understanding the characteristics of the silk screen printing, on the selection of printing method, can foster strengths and circumvent weaknesses, highlight the advantages of screen printing, to achieve a more ideal printing effect.
