Labeltech OP Varnish

Labeltech is the new generation water based inks formulated to be user friendly on the printing press. These inks are characterised by their ability to provide high quality prints with minimal on press adjustments.

The inks are of a neutral ph that translates into low odour around the press. The major application is for Flexo and Gravure overprinting to give high gloss and better resistances to moisture, oil, climate etc. on a number of different substrates. Labeltech OP Varnish has the capabilities of printing on both porous as well as thermoplastic substrates and with minor adjustments in the formulation. The ink will maintain adhesion and film integrity. Labeltech can be used on both fast and slower machines on a number of stocks. This ink can be used with or without bladed inking systems.
