Silk screen manufacturer several necessary conditions

The plate is necessary if the manufacturer of screen printing, plate making quality is not good, then you won't come out a good product, but improper in the occurrence of failures and processes and the use of materials, so in order to make the quality of the screen, according to process requirements, correctly grasp the plate technology, strict selection of plate materials plate.

First, in order to make a good plate, we should consider the silk screen, because the good seihan has many requirements on the performance of wire mesh, such as: must choose large tensile resistance, elongation at break small wire mesh. Because if the elongation is too large, it means that the stability of the plane is too poor.

Second, the resilience of wire mesh also requires better, because the resilience of the better, when the screen stretched to a certain length, after the release of external force, the better the ability to restore, the edge of the printing is also more clear. Of course, at the same time, the ink of the silk screen and resistance to chemicals are also required.

Third, in the silk screen manufacturer, for the net frame and stretching screen choice, must choose the frame precision is high, the size is relatively stable. For wire mesh material, we usually choose nylon mesh and polyester silk screen. When the net is stretched, the pneumatic stretching machine is the best choice. The tension must be well controlled during the stretching of the net, and the force must be evenly distributed. At least 24 hours after the net is stretched, make sure that the points can be stressed evenly and prevent the mesh from deforming. A good CNC is usually placed for 2-3 days.

Fourth, for the production of screen printing template, the use is the most direct legal version, want to get high quality screen template, it is necessary to pay attention to the thickness of the coating, glue sizing should be uniform, but also control the drying, exposure and development etc.. Because the screen plate requirements plate photosensitive material performance is good, easy to apply, but also to the photosensitive spectral range, if because of high sensitivity, can achieve the purpose of saving energy can be more rapid plate. The utility model has the advantages of good developing performance, high resolution, good stability, easy storage and waste prevention.

Finally, the photosensitive material selected correctly, it is easy to form a good version of the film, a good version of the film can adapt to different types of ink performance requirements, but also to a greater extent withstand scraping squeegee.
