Screen printing film material with UV ink does not match how to solve

Date:2013/10/13 18:11:57 Hits:5124
 

     Screen printing machine printing on thin film on the surface of the material is better than printing on the surface of the paper, the UV ink is easier to fall off, this is mainly because the surface tension of the film materials is low, the UV printing ink to firmly attached on the surface.In general, the surface tension of the membrane material must be more than thirty-eight mn/m can be combined with UV ink is firm.

     Solution: thin film material before delivery, supplier shall be on the corona and coating processing, in order to increase the surface tension.

     Compared the two kinds of processing methods, corona treatment costs are lower, but the stability of the treatment effect is poorer, the corona treatment effect will be weakened gradually with the extension of time, especially when the thin film materials stored in a humidity larger environment, corona treatment effect weakening faster.

     Therefore, in the actual screen printing process, to achieve good printing effect, Suggestions of corona treatment to thin film materials for on-line corona processing.Although coating processing cost is higher, but its treatment effect is stable, and the surface tension is not affected by time.
