Two new ranges of UV inks, all designed for label printing on narrow web presses, are being featured at the show. One has been developed to give optimum adhesion on a wide range of impervious substrates rationalising the use for just one ink. The other is a new ultra high strength series developed to meet the demands of today’s high speed printing presses using HD plates with very fine screen aniloxes. Pulse is also launching its own brand UV flexo bright silver ink, allowing for a more cost effective printing of small areas normally foiled.
Varnishes for digitally printed webs are available in gloss through to super-matt finishes as siliconised and overprintable/blockable versions. The Digitech range featured will include varnishes formulated to exhibit excellent adhesion and resistance to heat, water and chemicals, as well as a range for wine labels where improved scuff and rub resistance is required. The range also includes UV flexo, rollercoat and duct applied primers that accept digital inks.
New screen varnishes being presented at Labelexpo have been formulated to optimise the adhesion properties for improved abrasion resistance. These varnishes can be used on a wide range of label and packaging substrates, such as antique wine label papers and synthetic substrates, using established flexo and rotary screen processes. UV rotary screen varnishes have also been specifically developed for braille fonts. These include those used for pharmaceutical packaging, allowing the printed image to meet current CEN standards for dot heights, as well as other formulations suited for high build applications such as warning triangles.
