Polytype's Virtu Vetro ink series for UV-curable production onto glass surfaces has successfully completed a series of performance tests. The results confirm the compatibility, durability and behaviour of the Virtu Vetro range of CMYK and white inks on float, safety and other glass types for a variety of industrial digital printing applications. Developed by the Swiss manufacturer for its Virtu range of wide- and superwide-format industrial printing technologies, the inks were printed onto glass panes and examined by an independent, accredited testing laboratory. A primer Virtu bond was used to pretreat the substrate, which was then printed in controlled conditions before being tested in 21 categories. Of particular interest are conclusions showing the ink's durability. Virtu Vetro is confirmed to perform well with tapes and adhesives, even under stressful conditions; one stress assessment undertaken when using a silicone-based adhesive demonstrates full adhesion after two weeks of continuous testing. The inks are verified as highly resistant to abrasion, scratching, grinding and polishing and do not chip or flake when cut. For more information please visit: www.polytype.com/en/
