Durst Industrial Inkjet Application GmbH is a leader in the field of

flatbed inkject printers for 15 years, and offers innovative digital printers for industrial applications. As part of in-dustrial manufacturing pro-cesses – wooden boards for furniture, door panels or flo-ors, metal plates for cans or façades, synthetic parts for car interior fittings or control consoles – surfaces are em-bellished with decorative fini-shes. The digitisation of sur-face printing via digital inkjet printing provides an answer to the increasing cost pressu-re in the industry caused by smaller batch sizes, the per-sonalisation of products and copy-protection for branded products. An additional bene- fit is that with the functional nano-inks developed throu-gh intensive research, fun-ctionalisation of surfaces ,as well as decoration, can be carried out.Durst Application is spe-cialised in this digital coa-ting technology in industrial manufacturing processes. One of the largest and most interesting fields of applica-tion is the flat glass area. In the field of glass, inks with inorganic pigments and zinc frits are fired at 680-700°C during ESG production. In the process, the colours have a greater colour space than previous colours due to spe-cial pigments developed in collaboration with university research departments. Their density and opacity exceed standard requirements.

With the Rho Vetrocer 250, Durst offers a robust inkjet printer with inorganic cera-mic inks for glass processers in the area of façades and glass applications with ex-treme surface requirements. Durst’s own patented print heads with continuously cir-culating inks prevent nozzle outlets clogging, a problem which can otherwise occur due to sedimentation of the inorganic pigments. The nozzles are therefore always ready to use without long cleaning procedures. A spe-cial printing programme, which intelligently combines the process colours, inclu-ding white, enables the same colours to appear as brillian-tly as in offset printing. The printer with special glass feed tables can be integrated into existing glass production lines or be operated as a stand-alone, fully automatic production system. As prin-ting is carried out directly from a digital dataset, no costs are incurred for tem-plate creation or in set-up times. Companies benefit from these cost-efficient so-lutions both on small print runs and also in series pro-duction.The Vetrocer builds on the tried and trusted Rho printer series in the graphics area; supports, nozzle carriages, electronics, and the Rho series software have been combined with nozzle heads, ink feed systems and media transportation specifically for glass printing to create a printer which meets the

needs of glass printing and the special requirements of the industry.Durst’s inorganic ceramic ink was developed special-ly for printing on glass. The ink is printed directly onto the glass without a primer and combines permanently with the glass in the oven at a temperature of 680-700°C on the base of the frits con-tained in it. The ink is availa-ble in black, white, red, blue, yellow, green and “Satinato” colours, offers perfect UV protection and is opaque, depending on the printing intensity. It has test certifi-cates, is fade-proof for at least 15 years and can be used for the protective black edge of frameless façade glazing or equally well for win-dows in transport vehicles (rail wagons, cable cars and track-bound vehicles).The areas of appli-cation of the Rho Vetrocer include the manufacture of brightly coloured glass for all areas of outdoor use such as glass facades, solar panels, car windscre-

ens, garden ornaments, per-manent signs or panorama maps made of glass etc. as well as for interiors, such as glass for furniture, inter-nal partition walls, kitchen backsplashes or bar deco-rations, panels for lifts and equipment and much more.Durst Industrial Inkjet Ap-plication is a subsidiary of Durst Digital Technology. Its head office is located in a new LEED-certified building in Lienz, Tirol. On its stand A71 in Hall 12, DIIA presents the future of glass printing for the first time at glasstec 2014.
