Pulse Roll Label Products has developed a UV curable, silicone-free opaque white ink for rotary screen printing. Combi SF is formulated to permit use as a first-down white for subsequent over-printing by letterpress and litho, as well as screen inks or varnishes.
“White inks for screen printing normally include silicone compounds to enhance ink flow-out and surface evenness,” says Pulse Technical Manager Chris Price. “However, silicon additives often make it difficult to over-print with other processes such as letterpress, litho, flexo or varnishes. Our new white formulation means that customers will be able to successfully over print on a wider range of processes and materials.”
Optimised for high opacity and whiteness Combi SF can be used with a number of screens including Gallus and Stork. A wide range of substrates can be processed including coated/treated PE/PP, PVC, Polyester and some foils.
