The reliable and abrasion-resistant printing of high-performance plastics poses a challenge for all areas of industry. A typical example is the printing of PTFE (polytetrafluoroethylene) using inkjet printing. Prior surface treatment with cold atmospheric pressure plasma enables high-quality and reliable marking with as little effort as possible. Plasma treatment greatly improves the adhesion of printing inks to PTFE, which is difficult to print on. The compact PiezoBrush PZ3-i plasma unit or the PiezoBrush PZ3 hand-held plasma device for manual pre-treatment of small batches makes integration into existing production lines particularly easy. Plasma functionalization at atmospheric pressure means that expensive vacuum systems or toxic wet chemistry can be avoided, with benefits for costs, safety and the environment. While data matrix codes used to be made by laser or embossing, they are now increasingly being used as printed code images. Here, the code must have both good legibility and abrasion-resistant printing. One tool solution for surface processing is the PiezoBrush PZ3-i in conjunction with the KEYENCE MK-G1000SA continuous inkjet printer for marking PTFE fabrics.
