Ritzi Industriedrucktechnik GmbH uses the plasma handheld device piezobrush for the pre-treatment of PEI in industrial printing.
Plasma pre-treatment before printing has established itself as a standard process in recent years. Plasma in printing industry is used in all common printing processes such as digital, pad, screen or offset printing. The adhesion of the inks and varnishes to the surface is enormously improved by pre-treatment with plasma, which significantly increases the print quality. The surfaces of many materials such as metals, glass, ceramics and even natural materials such as wood and textiles are often very difficult to print on, but are susceptible to plasma functionalisation. Plasma pre-treatment allows many polymers with typical “non-stick” surfaces to be successfully printed and coated after plasma treatment.
