The screen mesh number, wire diameter, screen weaving method or selected materials in screen printing will affect the tension of the stretched screen. When the screen is stretched, the tension of the screen is measured according to these parameters. Also note that the stretch screen requirements for screen printing screens.
Tension requirements for screen printing meshs: The required tension of the screen templates for different uses is also different. For manual printing, rough printed products, or those with no requirements on accuracy and size, the tension is> 6N / CM. I
t is worth noting that when the color block is overprinted, in order to make the overprint position accurate, not only the screen tension should be greater than 10N / CM In addition, several stencils of the overprint must achieve the same tension, which is more important for halftone printing, otherwise it will cause deviations in moire and hue.
It is also necessary to pay attention to the material, section size, shape and flatness, strength and aging treatment of the screen frame, which are directly affected by the tension of the screen and the stability in the use of the tension. In most cases, the main reason is that the tension of the screen template decreases when the screen frame is not strong enough.
The material, cross-section size, shape and flatness, strength and aging treatment of screen printing screen frame are directly affected by the tension of the screen and the stability in tension use. In most cases, the main reason is that the tension of the screen template decreases when the screen frame is not strong enough.
