The new UV-curing opaque white launched onto the market under the product name CombiFlex YSR-X55400 by the printing ink manufacturer Zeller+Gmelin GmbH & Co. KG on the occasion of the Labelexpo Europe 2015, demonstrates unique properties. So it is for example - as the name already suggests - equally easy to process both in UV-flexo printing and in UV-screen printing. With solid areas, the ink layer is smooth and uniform, but even with fine lines, an accurate print is also guaranteed.

The new development is an ink already adjusted to be ready for printing and is fast curing, with very good opacity and a very high degree of whiteness. It is silicone-free, so that in practice it can be used not only as a standalone printing ink, but it is also suitable as a first down white and can be overprinted with printing inks in other processes. It can be combined with finishing processes such as hot or cold foil stamping and can even be subsequently marked or printed in thermal transfer printing. The opaque white also offers high scratch resistance and good adhesion to films, paper and metallized substrates.

For the application of CombiFlex YSR-X55400 by screen printing, screens by major suppliers such as Stork, Gallus Screeny or Kocher+Beck may be used. In flexo printing, the opaque white can be applied using anilox rollers within a line-count of 100 to 140 lines / cm and with a pick-up volume in the range of 8 - 14 cm³ / m². According to an announcement of the printing ink manufacturer from Eislingen, the first practical applications of the product have delivered excellent results in terms of whiteness, opacity and gloss.
