        When used in screen printing machine for printing production we can't always avoid to make decontamination processing for the silk screen printing screen, but we often use silk screen printing different kinds of products are often caused by the dirt on the screen cleaning not clean, the result is that waste, influence printing quality and shortened the service life of the template.Today for you the detailed introduction of screen printing screen dirt out method.
As the picture, there are dirt or dry ink in the printing area, should make decontamination processing for the silk screen, stop printing press, the net frame is raised, then some operators will dip in with the solvent of emery cloth hard hard template, can listen to the voice of the whole printing workshop, often damage of template.

       A truly knowledgeable operators rarely graphic printing surface friction force template type, because he knew that the printing figure of all the graphic edge clarity demand keeping up clear graphic interface emulsion layer.Graphic interface friction force can be damaged by emulsion layer, or even erase emulsion layer, leaving only bare mesh.

     When printing high network cable for color images, silk emulsifier film only below 5-6 um thick, mesh own silk diameter perhaps only 30 um, giving friction force.Therefore, the key to avoid rough decontamination is first of all should prevent template being polluted.

      The main cause of the pollution of template is improper ink control, causing dry ink in the mesh.When using solvent ink or water-based ink, the reason is that ink too thin or too thick.Should be in the state of the ink does not change.When using UV curing inks, should strive to avoid screen under ultraviolet light irradiation, also want to avoid sun exposure.
