Screen printing features a lot of, the most fundamental point is printing adaptability is strong, so people call it, except the air and water can't print in all the different materials and surface shape can be performed on different substrates printing, and is not restricted by the printing area size.Screen printing has the following characteristics compared with other printing method.
(1) of low cost, quick effect
Silk screen printing can be mechanized production, also can manual operation, its investment but can small, can engage in individual manual production from thousands of yuan, YinChang to tens of millions of yuan to build a modern network.Due to this kind of printing method required equipment and material cost was lower than those of other printing method, another method the plate making and printing method is more simple, so the current special interest, under the personnel, creating reemployment opportunities for them.The flat printing, embossed, intaglio printing can't do simple printing can be finished with screen printing.Shanghai printing screen printing can be divided into industrial screen printing screen printing and fine art.Art silk screen printing can be used to print fine print and copy the rare paintings, its products are bright color, ink layer thick.Frame body feels strong, is other printing method.
(2) to adapt to the irregular printing on the surface of the substrates
Silk screen version of exchange-rate flexibility, in addition to printing on the flat object, can also be in curved surface, spherical or uneven special-shaped surface printing, such as all kinds of glass, plastic, bottles, lacquer ware, wood, etc., in the flat printing can't be printed, embossed, intaglio printing method, it can be printed.
(3) strong adhesion, good example
Because of the characteristic of the silk screen version, printing ink through the screen hole, attached directly Yu Chengyin surfaces.According to the requirements of substrates materials available both ink printing, also can use all sorts of coating or printing paste, mucilage, etc.While other printing method is due to the small requirements for printing ink pigment particle size, and restricted.
(4) ink layer thick, stereo sense is strong
In the four printing method, screen printing ink layer is thick, graphic rich simple sense, stereo sense is strong.Offset printing ink layer 1.6 microns, embossed is about 5 microns, intaglio printing ink layer of about 12.8 microns, flexible printing ink layer thickness of 10 microns, and silk screen printing ink layer thickness can reach 60 microns.Thick film screen printing ink layer thickness to 1 mm or so.Silk screen printing used in braille, printed ink layer thickness is 300 microns.Its method is through the braille machine, according to the original on the silk screen version directly into Yang figure, and after printing of bubble ink printing line, heating dry immediately, namely can form the braille.
(5) the light fastness is strong, looks good
If use the black ink in coated paper last impression after comparing measured maximum density of assorted range, gravure offset printing is 1.4 embossed is 1.4 to 1.6, and the maximum density value of the silk screen printing range can be up to 2.0 so the light fastness of silk screen printing is extremely strong, colour also better than offset printing.In offset printing, if want to proofing mechanism cover the opaque white seal surface, will be in the same place zhu 3-4 times, it is possible to silkscreen print only once.In the printing quality of assaying the sexual, even the same color printing color quite shallow light printing quality, the simple sense of silk screen printing and colour and lustre is far more than the offset printing.
Silk screen printing ink layer thickness can be thick, also can become thinner.Such as in four-color screen printing and network tinted, Shanghai printing requires each color ink layer is not thick, but a thin layer of ink.Ink layer thinning method is by changing the printing speed, ink viscosity, wire thickness, scraping plate shape, printing pressure, and details the Angle variable factors such as, can make screen printing ink layer thinner, even thinner.
(6) substrates
Can be paper, cardboard, wood, metal, textile, plastic, cork, ceramics, glass, leather, fur, t ransfer paper, transfer paper, and the combination of various materials, so the silk screen printing in addition to the wisdom of printing industry week in all applications, is widely distributed in printing and dyeing, clothing, advertising, radio, electronics, ceramics and packaging decoration industry.
(7) printing format
Now ping "letterpress printing, gravure and flexographic printing are subject to restrictions on the size of printing format, and the silk screen printing is can undertake large format printing.Especially at present, along with the rapid development of the advertising market, screen printing large outdoor advertising print for a growing proportion in the advertising market.Now the most large-format screen printing outdoor advertising can reach 2.2 * 3.8 m and 2.2 * 4 m.
