Screen printing machine making lithograph plates, the printing craft, have the following several essential requirements to silk screen's performance:
1. the stretching resistance is big. The stretching resistance intensity is when refers to the silk screen the pulling force, the resistance destroys (break) ability. Moreover, after the silk screen moisture absorption's intensity change should be small.
2. The break elongation ratio is small. The elongation ratio is refers to the silk screen to break the time elongated quantity under certain tensity and the original long ratio, by percentage expression. The elongation ratio is big, the plane stability is bad, but the silk screen also requests certain tensity (about 3%) under to have the enough elasticity.
3. The rebound elasticity is good. After the rebound elasticity is refers to the silk screen to stretch certain length (for example elongates 3%), when relieves of the external force, its length reply ability, the name elongates the multiplicity, its value is bigger is better, after the snapping back, after India, the edge is clear.
4. The heat resistant humidity change's stability is good.
5. The printing ink adopts the performance to be good.
