1.Ink preparation see the leak rate of wire mesh
      Thick thin degree judgment method, the thick degree to ink through the screen, printing does not appear on the surface of silk screen net or drawing as well.Thin degree to put on silk screen, printing ink with its weight can achieve through the mesh but not drip for the best.Printing fine line, should be the weak point, on the other hand, should be strong point.

2.Choice screen in the printing quality

      The quality of the wire cloth with uniform diameter, mesh number is accurate, consistent and stable quality.General selection of mesh is 450 ~ 500 mesh.Fine lines, printing ink fineness high, the poor absorption of substrates, should choose high number of mesh screen, on the other hand, should choose low number of mesh screen.Plate making the location of the graphic on the screen and screen size should be according to the structure, size and substrates of substrates on graphic position and determine.If the design is bad, will affect printing quality, and even can't screen printing.In addition, the same was printed on the graphic, had better use a screen printing.As is divided into two printing with Internet access, process will reduce the qualification rate of screen printing.

3.Scraper watching the surface roughness of substrates

      Use the blade material for polyurethane.Polyurethane rubber scraper abrasion resistance, solvent resistance and resilience is better.Its hardness, choose 60 ~ 80 shaw.Large screen tension, surface smoothness good substrates, should choose high hardness of the scraper.On the other hand, should choose low hardness.Sex differences in surface, low spherical or flat (local projection) printing on substrates, blade width should be narrow shoulds not be wide.

4.Screen orientation relationship pattern clarity

     The plant using the fixture materials are metal, wood, plywood, PVC transparent sheet.Such as location, size of substrates and small, should choose metal fixture.Such as graphic is relatively close to the edge of substrates, should be fixed a beside the substrates and substrates edge of flat wood, lest by easy to paste.Net is apart from the average of 1.0 ~ 2.5 mm.Such as printing design easy to paste or reticulate, shall mean the net distance.

5.Screen printing process

      Printing pressure is high, the quantity of ink is much, but the screen is easy to deformation, so scrapping printing pressure should not be high.Scrapping printing speed often is 60 ~ 200 mm/s.Scrapping printing speed, the ink quantity is little, but not easy plugging.So easy plugging ink, printing speed should be faster.Scrapping printing line for line, three kinds of diagonal lines and curves.Should be based on substrates smoothness and the distribution of the graphic on the substrates.Scrapping printing line length and ink consumption of large, ink quantity should be even more to shave a layer of ink, after printing.
