[China Glass Net] In glass screen printing products, the problem often occurs is the presence of jagged burrs (including defects or broken wires) at the edges of the printed ink film. There are many reasons for burrs, but the main reason is the quality of the screen printing version. 1 The sensitivity of the photosensitive adhesive is not high, which causes the fine line mountain to be broken or broken. 2 The exposure time is insufficient or the exposure time is too long, the development is not sufficient, and the edge of the screen printed graphic is not neat and jagged. For a good screen printing plate, the edges of the graphic should be smooth and tidy. 3 When the surface of the screen printing plate is unevenly coated, there is still a gap between the screen printing plate and the substrate during printing, and the edge of the printing ink is burred due to the ink vacancy. 4 During the printing process, due to the expansion of the plate film after contact with the solvent, and the degree of warp and weft expansion is different, the surface of the plate film is uneven, and a gap occurs between the screen printing plate and the substrate at the time of printing, and the ink hangs in the air. The ink film will have burrs. In order to prevent the occurrence of jagged haircuts, the solutions can be considered from the following aspects: 1 using high mesh screen making; 2 selecting high resolution photosensitive plate making; selecting bridging type and good resolution Photosensitive adhesive. 3 Make a screen printing plate with a certain photosensitive film thickness to reduce the expansion deformation; 4 It is also possible to use a skewed stretch net method to stretch the net, and the good angle is 22.5. 5 fine line printing, can also use indirect plate making method, because the indirect legal version of the burr may be smaller: 6 in the plate making and printing process, try to control the temperature expansion factor, use a small expansion coefficient of photosensitive material: 7 improve plate quality To ensure that the surface of the screen printing plate is smooth and smooth, and the edge of the screen line should be neat; 8 spray the screen printing plate with a water spray gun to improve the development effect; 9 the distance between the screen plate and the substrate, the blade angle, The printing pressure should be appropriate.
