1. The selection of screen printing press: choose high precision screen printing machine, version of the lifting of screen printing machine frame as well.Before the start of the screen printing, screen printing machine for precise debugging, to ensure the smooth progress of screen printing.
2. The printed glass according to the requirement of the user may have different rules such as the shape or size, need to cut glass as required.And then pour edge grinding, cleaning, can be used only for glass completely dry.Should pay special attention to is here, the glass surface can not have water, otherwise will seriously affect the final printing effect.
3. The glass screen printing ink selection: in glass order of adjustable screen printing, screen printing ink than the covering power of offset printing ink, so to use yellow, green, black four-color ink transparent toughened glass.
4. The glass screen printing net: the choice of tense in the process of stretch mesh chose the wire mesh and mesh frame, combine the two, this is stretched.Screen tension with the correct tension net technology, uniform stability is very important, and the change of the tension will affect the ink through the ease of, causing network shape change.If uneven screen tension in screen printing, printing ink can make a difference in quantity through.Dot will appear in different areas and different deformation turtle grain.To guarantee the accuracy of the overprint and the stability of screen printing process parameters, four levels adjustment screen printing requirements four web version of the stretch mesh tension is not only to achieve an appropriate level, and the tension values should be consistent as far as possible, just stretched good cannot be applied to production immediately, and to place two days or more, the tension stability.Net frame size selection should also be consistent and had better choose metal screen frame.Tension network at the same time as much as possible to ensure the mesh and screen frame transverse vertical.Network to a lot of tense, luminous characters, manual, electric, pneumatic ways can be used, the more advanced, can stretch quality net edition is pneumatic and electric tension machine.Stretch mesh requirement is uniform tension, net geographic remain vertical, sticky glue is strong, screen printing can't slack.
5. The glass screen printing screen frame choice: the choice of net frame is more formal and less deformation of net frame is aluminum alloy net frame, its size should be bigger than design, the outside part of the specific size should be design from net frame should be between 70 ~ 100 mm.Additional selection screen frame, its strength is very important, the key is a horizontal rigid enough.
