PCT and PTC technologies are used to enhance print operation during press operation. The new ONYX series of presses feature Uteco's latest hardware and software devel- opments that automatically set print register and printing pressures at job start, reducing both waste and changeover times, ensuring optimum press performance and maximum return on investment. ONYX can be supplied in five different models: • ONYX 612 GL: a 6 color long repeat press • ONYX 808/810/812 GL: three 8-color presses with traditional or long repeats • ONYX 810 & 110 GL: two 10-color presses with traditional or long repeats Other features include: • PCT - Press Control During Transition New Uteco platform for low waste and fast setting of printing pressures (Touch & Go + Kiss & Go) and registers (Click & Drag) in partnership with Grafikontrol • PTC - Predictable Torque Control This software system allows predictive control of plate mandrel servomotor's torque in varying print conditions to ensure best available print register accuracy • Direct Drive Evo The Direct Drive Evo technology by Uteco grants unique performances which give converters important benefits • Chamber Doctor Blade The new pneu- matically loaded chamber doctor blade features: » Newly designed lightweight and robust doctor blade chambers » On deck toolless end seal replace- ment » Fast change toolless doctor blades • Sprint Wash The ONYX can be equipped with SprintWash, Uteco's automatic and modular washing system. Three different washing cycles (light, medium and heavy) can be selected per deck, based on need by the operator on the machine supervisor customer. The press is completely gearless and equipped with single motors on counter pressure rollers, all connected via an electric line shaft. Servomotors are installed on plate cylinders (direct drive) and anilox sleeve cylinders. Both the printing plate and the anilox use sleeve technologies to facilitate fast changeover. This machine's technology is mainly used for printing on paper, paper- board and aluminum but can also print labels and materials laminated with aluminum for packing of special food or juices. The Onyx SIL can be equipped with alternative drying systems, as well as with heat curable energy systems, such as UV lamps or an EB group, or any combination required by the custom- er. Inline rotogravure units are often used to apply lacquer or varnish inline with printing, as well as to apply adhesives to perform in line lamination. Main options include: • Inline viscosity control • SPRINTWASH - Automatic washup system • Flying job changeover possible on un- used printing decks • Automatic register control between colors • Video cameras for front and back print- ing inspection • Automatic setup of print pressure at press startup • Possibility of front and back printing • Electric, diathermic oil, steam or gas heating systems • Motorized air recirculation systems with LEL control • Wide range of winders Logipack for printed roll and core handling • Inline slitters • Inline die cutters Quartz The new generation of stack type from Uteco features: • Sleeve change for both the anilox as well as the plate roller • Servomotors to drive the inking rollers (optional item) Using the same printing unit utilized for the TOPAZ 6C-CI/GL, QUARZ is the new series of 2/4/6/8 colors stack type introduced by Uteco in the market for inline (to film extrusion lines or to bag making machines) or for reel to reel applications. In the gearless solution, all counter impression cylinders are driven by their servo motors and all servos are linked together by the well tested and reliable Uteco electric shaft. With its sturdy construction, it can be applied also for wide webs and important print repeats. Specification Technical Details Print Width 24-in. -- 63-in. Minimum Print Repeat 12-in.
