Drying, Curing & UV
UV and LED solutions for converting and label printing
narrow-web label printing, is equipped with Aniflo offset technology as well as a hot embossing unit, and full LED features - IST METZ’s latest generation of MBS LEDcure-series air-cooled high-performance LEDs. The Viva Aniflo has the typical output of a

conventional printing process, but also the flexibility of digital printing. This is further enhanced by the use of MBS LEDcure, which was shown for the first time in live printing demonstrations, highlighting the combination of waterless
offset printing and LED UV curing. IST METZ’s
Hot Swap concept was initially presented at
rench printing press manufacturer, Codimag, presented a VIVA 340 at this year’s UV DAYS. This machine, designed for
Labelexpo in autumn 2015. It enables users to switch between tried and tested UV lamp technology and new LED technology at any time during the production process. During the switchover the outer housing remains in place on the machine and the LAMPcure unit is exchanged for a LEDcure system, designed in the form of a cassette. The insertion process automatically creates contact with the supply connections, and the entire exchange is completed without tools and within a very short space of time. More users are asking whether it would be
more profitable to convert a business’s production process to the new LED technology. If they decide in favour of conventional UV units, they can rely on
a technology that has proved itself over many years. However, the benefits of using LED technology at the right time might then be missed. To make it easier for users to reach a decision,
over the next 12 months IST METZ is giving customers the option of trying out the MBS LEDcure LED solution free, for one month, when they purchase a MBS LAMPcure. Based on the new Hot Swap concept, designed for narrow- web printing, this enables users to have the opportunity to switch between both technologies in order to evaluate the individual application possibilities.

tiquetas y Gráficas, (Etygraf ) is based in Sueca not far from Valencia, Spain. The printing methods used by the company are aqueous and UV flexo printing, UV screenprinting and digital offset printing. Etygraf serves a wide customer base of over 750 clients in the fruit, vegetable, wine and food-processing sectors as well as pharmaceutical, health and general industries. The company’s product range
E
comprises labelling solutions using digital printing, flexographic printing and screenprinting technologies. Its business strategy is built on added- value design, quality assurance management and technologically advanced solutions including design,

Mateu, explains: “We mainly print and coat self-adhesive white and clear PP and paper labels with two-face versions at speeds of up to 120m/min. We particularly appreciate the possibility of switching between or running simultaneously with mercury arc and LED UV as not all inks and laminates are as yet available as LED versions.” Etygraf eventually opted for a GEW
material selection and production. The company was founded in 1981 and today employs 65 staff working in two shifts. David Baldovi, marketing and communication at Etygraf, says: “Over the past years Etygraf has enjoyed tremendous commercial success with growth culminating at over 20 per cent in 2016 and our production has reached over seven million square metres of labels per year.” In 2016 Etygraf installed the new
flexo label printing system with eight printing, coating stations complementing three existing Gidue flexo machines also fitted with GEW UV systems. The new machine is based on a 40cm-wide Bobst M4L printing press and able to print eight
UV system: comprising eight LW1 high power LED UV lampheads with hybrid RHINO power supplies. The decision was due to Etygraf’s desire to invest only in futureproof high- performance technologies. The abilities of the combined LED and arc UV hybrid operation were a key point in the purchasing decision. José Carrasquer, in charge of
purchasing and quality at Etygraf, adds: ”The LW1 is an LED UV curing solution that brings us consistent output and stable quality over time with the added benefits of instant on-off switching, long-term reliability and extended life cycles of the LED technology. “We use exclusively low
migration inks and wanted to raise
our quality standards for the complete production chain. For the UV curing component only GEW was able to offer us a package of efficiency, reliability and safe curing at high speeds,” he says. All new UV curing systems with RHINO power supply come as standard with GEW’s Embedded Service facility, which continuously monitors the UV system over the internet. This allows the manufacturer’s service engineers to remotely analyse system performance data, which enables them to proactively detect any out- of-tolerance parameters that may need maintenance and corrective action, well before a fault can develop. This type of remote preventative maintenance ensures the entire UV system operates at peak performance at all times, thus avoiding unplanned machine stoppages and wasted resources. Moreover, the new GEW UV
system, based on the LW1 LED UV technology, has the ability to print delicate, heat-sensitive materials and brings substantial savings in electricity consumption with environmental credentials.
