Topic: Plasma treatment for printing as alternative corona surface treatment. Better ink bonding and print adhesion of solvent-free inks. Printing on PP, PE, PA, PC, metal, glass, plastic.

Better ink bonding and highest print quality in all the usual printing processes thanks to plasma treatment

Openair® plasma technology is used as part of all the common printing processes like pad printing, screen printing, and offset printing. Plasma pretreatment makes print adhesion of solvent-free inks possible, as well as secure long-term adhesion when printing difficult surfaces like polypropylene (PP), polyethylene (PE), polyamide (PA), polycarbonate (PC), glass and metals. Openair® plasma’s high efficiency makes it possible to significantly increase machine speeds. When tubs or tubes are printed, an increase in processing speeds of up to 30% can be achieved.

Quality improvement of the overall print appearance

Better ink bonding by using Openair®-plasma treatment before printing achieves increased aging resistance, high resistance to handling and weathering, excellent ink brilliance, and flawless application of printing inks. In contrast to the corona process, the uniform, potential-free effect of atmospheric plasma pretreats even thermally sensitive surfaces without damage.
