Most use a plastic pen cheap PP material, in the case of adhesion to the less demanding, using a dedicated PP silk screen printing ink, can not use pre-press, but there are stringent requirements for adhesion with some users, then in the pen screen printing machine above the installation of the necessary pre-press processing equipment it is very important. Currently, all three mature prepress processing means are adopted: flame treatment, high-frequency processing, PP water wiping device. Pen smaller diameter, the process requires a 360-degree rotation, which increases the complexity of the mechanical structure. From the point of view, the ideal high-frequency processing, PP water wipe Secondly, flame treatment after home. Pen screen printing machine prepress device, effectively solves some pen surface residual stains and grunge ink resistance, increased adhesion.
