LED UV
|
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.
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.

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.

| INLINE UV CASTING AND FOILING |
 |
The need for added value has never been greater as print companies become increasingly competitive and look for ways to differentiate themselves. Holographic coating and foiling are increasingly being used to print packaging for cosmetics and luxury goods, and to achieve unique effects for book and magazine covers. Responding to this trend, Ryobi has developed a new UV casting and foiling system for the Ryobi 1050 and 750 series machines.
Ryobi's system uses various types of holographic coating and foiling in-line. |
|
UV Holographic coating process
The relief texture and pattern of the film are transferred to the UV varnish, then the printed surface is cured by UV light to produce the holographic effect |
The printed sheet is coated with UV varnish |
A holographic coating film is adhered to the surface of the varnish coating before curing, then the film is irradiated by UV light |
The detailed relief texture and pattern of the film are accurately formed to the varnish coated surface |
|
UV foiling process
After applying UV adhesive with a printing or coating unit, the printed surface is covered with a film based foil. It is the irradiated with UV light so the foil firmly adheres |

Can be accomplished inline during printing
Space saving installaton
Several film patterns are available and custom designs are possible. Film can be rewound and used several times
The coating unit is used to apply glue for foiling and increase adhesive strength to the foil
The UV lamps of this system can be used for the delivery section. Replacement is easily accomplished in about 3 minutes.
The lamp unit remains in a raised position when not being used |
