Screen printing is the production of screen printing screen frame one of the important materials, screen printing screen frame selection of the right or not on the plate quality and the quality of the plate has a direct impact. In order to ensure the platemaking, printing quality and other requirements, according to the following conditions to select screen printing frame.
(1) Tension requirements
As the material of the screen frame, it should have enough strength to resist the tension of the screen. Because the screen has a certain pulling force on the screen frame when stretched, which requires the screen frame to have tensile strength, and if the strength is not enough, it will scratch Music, it will be deformed, it will not print a good print.
(2) should be prestressed
Stretching after the network frame bending deformation of the screen will have an impact on the stability of the tension, in order to reduce this effect, the frame can be prestressed.
Screen printing screen frame in the use of water to be often in contact with the solvent, and affected by temperature changes. When influenced by these external factors, the requirements of the network frame are strong and durable, skewed and other phenomena are not required, and repeated use of the network frame is ensured to reduce waste and reduce costs.
(4) light operation
Under the condition of ensuring the strength, the screen printing screen frame selects the light weight as much as possible, which is convenient for operation and use.
(5) good adhesion
Screen printing screen frame and silk screen cries to have a certain degree of roughness, in order to strengthen the screen and network box relay.
