Green machines from GAS

26 February 2010


USA based Graphic Arts Systems has launched the Eagle System Eco-Flow range of ‘ultra-green friendly’ print enhancement equipment whose Eco-Power drive is claimed to ensure the equipment uses ‘less power than a hair dryer when running at full speed’.

The range covers two applications: Eco-Foil lithographic coldfoil printing and Eco-Cast UV film casting (cast and cure) equipment. Both are said to leave the smallest possible environmental finger print in terms of recyclability and power requirements. Litho coldfoil is fully recyclable on the printed substrate and due to the fact that the used foil is rewound in the Eco-Foil system, the polyester portion can be reclaimed. UV film casting which impart a holographic finish to the printed sheet is recyclable on the substrate and the embossed polyester film is rewound and reused many times until eventually reclaimed.

The Eco-Power system developed by GAS allows for minimal power usage of less than 1 amp per phase to be used when operating at line speeds. The operational control of the equipment also ensures that coldfoil is fully utilised in the machine direction, by employing step and repeat procedures, and across the web by the ability to use multiple foil rolls.

Mike King, president and chief design engineer at GAS, states: By ensuring the maximum number of images from a given length of coldfoil, the system allows for the most efficient use of foil of any machine on the market and therefore the lowest cost, as the foil itself that is the highest single cost in coldfoil application. The power requirement costs are self evident”

The Eco-Flow is designed to fit on all types of litho press from 74cm-162cm and operates with a positive continuous foil drive ensuring that the ‘live’ side of the foil does not touch any of the rollers within the module. The modules will run with a maximum operating speed equivalent to 20,000 sheets/hour. Application on web fed presses is also available.
