Luminous ink preparation method

1 , transparent ink ;
2 , resolve conflicts and dispersion of light effects , luminous powder particle size should be selected more than 300 mesh powder material, some printing inks require a higher particle size of glow in the dark material  should be selected according to the actual situation of particle size , powder substance content of 20-50 % ( by weight ) ;
3 , luminescent ink grinding metal equipment can not be used , if necessary, can be plastic or enamel -lined ball mill or sand mill equipment using high-speed dispersion best way ;
4 , may be appropriate to add a photoluminescent films of transparent paint , tinting , but the afterglow indicators have different degrees of decline ;
5 , depending on the choice of different types of substrates such as transparent ink : metal substrates should be used metallic inks ; substrates PVC PVC inks should be used.
