Cheshire Anilox Technology to show new “break-through” engraving for UV printing at Label Expo
Cheshire Anilox Technology Ltd. has announced the launch of what it claims is a ‘ground-breaking’ new engraving, MaxfloUV, that maximizes the ink flow within the cells offering higher ink transfer at high speeds.
The new engraving is particularly suited to be used with the latest generation of high strength UV inks offering outstanding levels of colour density and a more even, consistent lay down without the problem of over inking and spitting sometimes encountered when using conventional engravings.
“Until now, highly pigmented UV inks would cause spitting when printing at high speeds” explains Sonia Arcos Sales Director of Cheshire Anilox Technology. “Following requests from our customers Cheshire Anilox specifically developed this new engraving to overcome this problem”
This unique cell profile incorporates all the benefits of its predecessor the maxflo but with an enhanced design enabling the ink to flow freely from cell to cell. As press speeds increase, the ability to consistently and effectively fill the cells on the Anilox with ink in order to deliver a uniform ink film thickness to the plate becomes more challenging. The cell depth-to-opening ratio is of critical importance. Deeper cells may mean greater volume. However, if the surface tension of the printing plate is too low to pull the particles of ink from the cell, then transfer will be very poor. By widening the bottom of the cell we have improved the ink transfer. By linking the cells we have eased the ink flow which causes UV spitting or spray that happens when a build-up of ink stay behind the doctor blade causing vibrations that will result in spitting.
The new engraving has undergone extensive field tests with Cheshire Anilox Technology customers and has been ‘engineered to perfection’. Samples printed with maxflo uv will be displayed at Label Expo.
Cheshire Anilox Technology will also present a wide range of innovative engraving technologies to suit the most challenging applications in flexo:
Proflo An engraving specifically developed for HD printing. It provides an increased ink transfer while also eliminating the chance of uncontrolled dot gain at ultra-fine line counts (+600L/cm). This now allows flexo printers to work with the expanded tone range of offset and rotogravure printing techniques.
EasyFlo HD for high opacity whites, achieves opacity levels of screen printing at faster speeds in one single pass.
