Plasmatreat’s plasma pretreatment for common printing processes

Plasmatreat’s Openair® plasma technology can be employed in all common printing processes such as tampon printing (intaglio), screen printing and offset printing. Plasmatreat’s pretreatment process enables the adhesion of poorly adhesive aqueous printing inks and secure and durable adhesion on difficult surfaces such as polypropylene (PP), polyethylene (PE), polyamide (PA), polycarbonate (PC), glass and metals. In addition, because of the high effectiveness of the technique it is possible to increase machine speeds. When printing onto tubs or tubes, for example, increases of processing speed of up to one third may be possible.

Qualitative improvement of the entire printed image

Plasmatreat’s Openair® plasma pretreatment as an additional step prior to printing lends increased ageing resistance to printing inks containing solvents. High handling resistance and weathering resistance, excellent color brilliance and more precise ink transfer are guaranteed. In particular, in contrast with the corona process, heat-sensitive surfaces are pretreated without damage due to the uniform action of Plasmatreat’s atmospheric-pressure plasma.
