CORONA TREATMENT

A process for treating plastics and other non-absorbent substrates to improve adhesion and printability. A high frequency electrical discharge is fired onto the substrate to increase its surface functionality (and dyne level), making it more receptive to inks, paints, glues, and coatings. Such substrates can usually be ordered “pre-treated” from the manufacturer or supplier, but Corona Treatment dissipates over time and in some cases may require re-treatment before printing. Our technical department can test your substrate to determine if it is sufficient for litho printing. See also: “Plastics”,”Reticulation”, “Dyne”, and “Surface Tension”.
