Selection of 1.UV printing ink in the screen of high tension, low elongation, S plain mesh or single sided flat screen. Net frame strength is good. 

The tension is the same 2 screen, error 2N/cm, tension is not the same, the ink layer is not uniform, and position deviation. 

3 net distance is generally between 2-4mm, should be adjusted according to the tension of the network distance. 

4 scraper at 60 degrees to 90 degrees of hardness selection, the general manual printing machine with 70 degrees, 80 degrees. 

5 substrate pretreatment. Because the substrate material surface condition is different, must carry on the surface treatment to the substrate, this to the UV ink adhesion is extremely important. For plastic film, usable dip in alcohol or isopropanol cleaning cloth cleaned and to remove floating in the substrate surface plasticizing agent and impure chemicals, such as dust, grease; for low surface tension of PP, PE, PU, PET material, according to copies of thick and thin, respectively, flame treatment or corona treatment, to increase its surface activity so as to improve the adhesion. After surface treatment of the surface tension of the substrate reaches more than 45 dyne / cm. 

6. Ink before use to stir, especially after the additive was added to stir evenly, otherwise it will produce some curing adhesion strong, some not cured or not fully cured poor adhesion, printing will produce adhesion. 

7.UV lamp power must meet the requirements, and adjust the curing speed. 

8 after curing and cooling to room temperature, using 3M-600# tape to carry out the grid test, 24 hours after curing, adhesion and solvent resistance to achieve the best. 

9 wash net, ordinary washing net, but not be able to use alcohol, because alcohol can damage the net template.
