Image deformation and how to solve?
Printed by the scraper when added to the plate on the printing pressure, can make between plate and printed matter is line contact is ok, not more than.Stress, plate and substrates on the inside contact, can make the screen scale, cause deformation of printing image.Screen printing is a variety of printing method of the minimum pressure of the China and India, if we forget this is not to print a good print.
If you don't increase the pressure can't print, reducing the gap between layout and the surface of substrates, so the pressure of scraper can be reduced.
What is a tensiometer?
Tensiometer measurement screen is pull its internal also fixed screen contact body traction between the size of the instrument.Tensiometer is mechanical and electronic type two kinds, measuring tension unit have Newton/cm said.Tension relative values can also be used to say.Cm tensiometer is stated as some numerical value relative tension, by tensiometer sank the screen its weight values (mm) to calculate the depth, tension values can be obtained directly from the dial, or indirectly from the control panel.Tensiometer has two kinds of manual and mechanical operation.Tensiometer is one of the most important is checking the quality of screen plate testing instrument.To ensure get plate-making required tension, tension network or tension in the process of network after using tensiometer measurement.
