Screen printer manufacturers: how to solve the problem of printing ink adhesion fastness

　　Screen printing machine manufacturers: How to solve the problem of printing ink adhesion fastness, let Zhengfei intelligent technology to tell you

　　Silk screen printing machine is mainly used in electronic processing industry, as well as color oil painting, poster, business card, binding cover and so on

　　How to solve the problem of adhesion fastness of silk screen printing ink

　　1. Implement humidity control on the printing site of the screen printing machine. Film and printing materials, such as cellophane and nylon, which are easy to absorb moisture, should be properly stored to prevent moisture.

　　2. Confirm surface precipitation. If the precipitation layer affects the adhesion fastness of printing ink, please replace the printing substrate or negotiate with the ink manufacturer for appropriate disposal. The first time to use film, as much as possible in advance to investigate its properties, characteristics, choose the appropriate ink;

　　3. Replace the ink or confirm the ink adhesion fastness. Gravure inks are mostly produced for specific purposes and should be avoided for other purposes or mixing different inks. And in order to prevent the misuse of residual ink to clearly record the relevant content, date, so as to reuse;

　　4, solve the problem of screen printing machine ink deterioration, bleaching;

　　5, adjust the drying conditions, solve the problem of residual solvent or reduce the residual solvent to the prescribed limit;

　　6, measure the moisture tension, if not qualified, update the printing substrate. Corona treated films, the degree of treatment is the most important; Whether the treatment is qualified and whether the wetting tension measuring solution is used for measurement;

　　7. Fully consider the effects of packaging contents and environmental conditions on ink adhesion fastness.

　　When you find the problem is not strong, please contact professional personnel immediately for maintenance, so as not to affect the normal use.
