Main Features of Screen Printing

Screen printing advantages are many, one of the most fundamental is the strong printing adaptability, so people call in addition to air and water can not be printed, in all different materials and surface shapes of different substrate can be printed on the ultra strong process, and is not limited by the size of the printing area.
Screen printing has the following characteristics compared with other printing methods.
(1) Low cost, quick effect Screen printing can be mechanized production, can also be manual operation, its investment can be small, from thousands of yuan can be engaged in artisanal production, to tens of millions of yuan to build a modern screen printing plant. Because the cost of equipment and materials for this printing method is lower than other printing methods, and its Seihan method and printing method is also simpler, so the current special interest of the people in the gang, for them to create re-employment opportunities. The plain printing, the convex printing, the gravure printing can not complete the simple print may use the silk screen to complete. Shanghai Printing screen printing can be divided into industrial screen printing and fine arts screen printing. Art screen printing can be used to print exquisite prints and copy valuable oil painting, its products bright color, thick ink layer.
The body of the picture is strong, it is the other printing method is beyond.
(2) Adapt to irregular substrate surface printing
The screen is resilient, in addition to printing on the plane, but also in the surface, spherical or uneven surface of irregular objects printing, such as a variety of glassware, plastic, bottle cans, lacquer, wood, etc., in the flat, convex, gravure printing methods can not be printed, it is able to print.
(3) strong adhesion and good inking Because of the characteristics of the screen, ink through the screen hole, directly attached to the substrate surface. According to the requirements of the substrate material, both available ink printing, can also be used for various paints or colorants, glue, etc. for printing.
and other printing methods because of the ink pigment particle size of the subtle requirements, but limited.
(4) thick ink layer, strong sense of three-dimensional In the four printing methods, screen printing ink layer thicker, graphic texture rich, three-dimensional sense of strength. Offset printing ink layer of 1.6 microns, convex printing about 5 microns, gravure ink layer of about 12.8 microns, flexo printing ink layer thickness of 10 microns, and screen printing ink layer thickness can reach 60 microns. Thick film screen printing ink layer thickness can reach about 1 mm. Screen printing is used to print braille, ink layer thickness of up to 300 microns.
The method is through Braille machine, according to the original in the screen version directly made Yang map, and the net printing ink, immediately after heating drying, that can form a point word.
(5) Strong light resistance, good fineness If the use of black ink in the paper on the first imprint of the maximum density measured after the comparison of the range, Offsctdruckereien for 1.4 convex printing for 1.6 gravure printing for 1.8, while the maximum density of screen printing can reach 2.0, so the screen print of the light resistance is very strong, the color is much better than Offsctdruckereien. In offset printing, if you want to use proofing mechanism to take white cover opaque printing, you should be in the same part of the 3-4 times, and screen printing only once on it.
In the color of the printed matter, even if it is the same color printing colors, screen printing texture and color far more than Offsctdruckereien. Screen printing ink layer thickness can be thickened, can also be thinned. For example, in the four-color screening screen printing, Shanghai printing requires that each color of the ink layer is not thick, but thin ink layer.
Ink layer thinning method is by changing the printing speed, ink viscosity, screen thickness, scraping plate shape, printing pressure and inking angle and other variables, you can make screen printing ink layer thinning, or even thinner.
(6) wide range of substrates It can be paper, cardboard, wood, metal, textiles, plastics, cork, leather, fur, ceramics, glass, decals, transfer paper, as well as a combination of various materials, so screen printing in addition to the printing industry in the intellectual week of all the applications, but also widely distributed in printing and dyeing, clothing, signs, radio, electronics,
Ceramics and packaging decoration industry.
(7) Large printing format Now the flat, convex, gravure and flexo printing are limited by the size of the printing format, while the screen printing can be large format printing. Especially at present, with the rapid development of advertising market, screen printing large outdoor advertising print in the advertising market accounted for the increasing proportion. Now the largest format of the screen printing outdoor advertising can reach 2.2×3.8 meters and 2.2×4 meters.
