Presstek claims the UV printing options, which will be
rolled out at drupa later this month, will speed up drying times and
high-fidelity reproduction on non-porous materials and uncoated stocks,
resulting in faster turnaround times and a higher quality.

The new process can be used for the production of
labels, direct mail, packaging, point-of-purchase materials and general
commercial printing. The company says the lightfast inks also offer increased
durability and quality when printing on foils, vinyls, films and plastics.

Klaus Schleicher, group product director, Presstek
says, "Printing with UV waterless inks on Presstek's DI presses expands
Presstek's opportunity to provide the highest quality, lowest cost four-colour
offset solution for a wider range of markets, including consumer packaging,
point-of-purchase and direct mail."

Schleicher also says, "With the DI implementation,
even faster turnaround is achieved with the UV waterless inks drying instantly
as each sheet exits onto a transport ramp, under UV lights and into a high-pile
delivery system."

He says, "UV waterless inks have the potential to
achieve greater densities than conventional waterless inks and provide superior
printing on a full range of plastics and specialty substrates, including
lenticular."

Two UV printing options will be available for both the
Presstek 52DI and 34DI, including field upgrades. The hybrid UV option that
allows for switching between standard waterless and UV waterless inks will be
available in the fourth quarter of 2008.

The UV option for operating the DI as a UV waterless
press will be available in the third quarter of 2008. The Presstek 52DI is a
52cm press with a maximum sheet size of 510 x 360 mm; and the Presstek 34DI is
a 34cm press with a maximum sheet size of 340 x 460 mm.
