Screen printing plate making, printing process, screen performance has the following basic requirements:
1.High tensile resistance.Tensile strength refers to the wire mesh by tension, resistance to damage (fracture).In addition, the screen moisture after the strength of the change should be small.
2.Small elongation at break.Elongation refers to the wire mesh in a certain tension when the elongation and the ratio of the original length, expressed as a percentage.The elongation is large, the plane stability is poor, but the screen also requires a certain tension (3% or so) with enough elasticity.
3.Good resilience.Resilience refers to the screen stretch a certain length (such as elongation after 3%), release the external force, its length recovery capacity, called elongation recovery, the greater the better, after the rebound, printed edge is clear.
4.Good stability in temperature and humidity.
5.Ink through the performance of good.
6.Good resistance to chemicals.
