Ryobi is the first printing press manufacturer to put LED-UV curing to practical use, and has been delighted with the reaction of the market and the interest shown in this product to date. The LED-UV curing unit replaces conventional UV lamps with long-life UV light-emitting diodes (LED's), cutting power consumption by at least 70%. Drying times are shortened, speeding up job completion, whilst the light source should last as much as twelve times longer than conventional lamps. The system generates minimal heat and no ozone, providing a real environmental plus, and eliminating the need for exhaust equipment to handle both heat and ozone.
This breakthrough technology is viewed by many as the most significant advancement in UV technology for 30 years. Light emitting diodes (LED's) are extremely efficient. Instead of using electricity to heat up a metal filament, LED's produce light by channelling an electric current through a semiconductor material. The result: close to 100% of the electricity is converted into light with virtually no waste heat generation.The LED-UV unit is now available for the two-up Ryobi 520 Series press, the B2+ format 750 Series, and the eight-up Ryobi 920 Series press. The LED-UV curing concept was awarded with the Nippon (Japan) Brand Prize at the 39th Machine Design Award competition in 2009.
