Labels&Labeling |111 Open House At a recent Edelmann Graphics open house, sales and administration director Julius Friedrich showcased an EvoPrint press with eight print stations – six offset and two flexo – which was later shipped to an undisclosed customer for the production of medium and long run labels. EvoPrint machines are delivered with 2-cylinder print inserts, and format change is achieved without breaking the web. The EvoPrint has two servo-motors per offset print station, the first one driving the print insert and the second the inking train. There is also a separate duct drive. ‘This allows us to prepare the print stations not used with the current job for the next one during production,’ noted Friedrich. In-line, closed loop ink density measurement is optional. cassettes for its first UV offset press, the Varyflex-F1 Offset. The press has a top speed of 200 m/min and is available in 340 and 430 mm web widths, with 520 mm under development. The range of print repeats is from 12" to 25", achieved by a 2-cylinder interchangeable cassette. The print units have a setting speed of 10 m/min to minimize start-up waste while water-ink balance is achieved, and the print unit is equipped with Omet’s ‘Vision 1’ automatic register system. A comprehensive report on the new press appears on page 61 of this issue. Intermittent solutions Intermittent, or semi-rotary offset presses, already provide an established solution to shorter run work with variable formats. Gallus pioneered this market with its TCS250 machine – now available with a rotary die-cutting option – and other manufacturers have helped evolve the concept. Rotatek’s Brava press, for example, is able to run in both semi- and full rotary modes (see L&L 1, 2009 p.63). Speeds in semi-rotary mode are around 50 m/min and 150 m/min in full rotary. The modes are changed by a simple change of printing cassettes. Codimag’s keyless Aniflo inking system first seen on the Viva 420 (see L&L June/ July 2008 p.26) uses a ‘flexo’ inking system of chambered doctor blade and anilox sleeve specially engraved to break down the paste ink to a film. The ink film is delivered to a transferred to the plate by a rubber form roller. Smooth Machinery is the latest manufacturer to enter the intermittent offset arena. Developed with Smooth’s Japanese partner Fuji, the SPM-4500R semi-rotary water-offset press is 450mm (17in) wide, giving a total print area of 430mm x 410 mm. Print speed is 12,000 impressions an hour and the ‘cool’ UV system will even handle shrink sleeve labels, according to Smooth. The press comes equipped with a UV flexo varnishing station and rotary magnetic die cutting as an option. It is driven by multiple servo drives with fully automatic web tension control and servo-driven segmented ink fountain rollers. The press has a Fife inspection system integrated into its Touch Screen control panel. A full range of converting options is available, include hot stamping, embossing, laminating, silkscreen and sheeting. Muller Martini PI 1385 Alprinta 74V The insider A round-up of the latest global label stories Booklet production drives refurbished R200 market Graficon Maschinenbau AG has delivered another two fully refurbished Gallus R 200 presses to customers in Germany. The two machines are equipped with some all-new units, including UV, electrical controls and register control. The machines are also equipped with the module developed by Graficon for the inline production of booklet labels. The base label is printed in the machine and in some cases first die-cut and the matrix taken off. The pre-fabricated leaflets are placed in register onto the web by a dispenser and are fixed by means of lamination or gluing and then die-cut to the final shape. 'The requirement for labels with a high content of information is constantly increasing, Booklet-labels meet these demands and therefore the market for these products is growing,' explained Graficon's Martin Erni. The customers for these machines asked to remain anonymous. Schober sells robotized stacker After successfully demonstrating its RSM 520+ 'S' Stack (Star Wheel) system at drupa, Schober has announced the sale of a similar model, but with in-line robotization ('V' Stack), for product stacking and counting. The high capacity stacking system has a third variant, the 'M' Stack, for very short runs. The 'S' Stack is optimized for long runs and the 'V' Stack for very large products and complex product layouts. The new machine will be ready for shipment by the end of March 2009. UV Ray offers low-heat and power system Maxwell WA is UV Ray's latest water-cooled, long-arc reflector with the same features and sizes of models with forced air cooling. It is fully extractable, has a low working temperature with reduced refrigerating power. The Maxwell WA system uses lowpressure water recirculation that enables the use of standard pipes (Ø 10 to 12 mm) and a compact refrigerating group. The manufacturer claims 30 percent energy savings for three every three reflectors installed compared to comparable systems. Another feature is 'Smart Start', a lowpower starter system claimed to reduce initial power requirements by 50 percent. Maxwell WA is optimized for both in-line and larger format central drum machines converting unsupported film. may 2009 | L&L
