While FoilStar has been able to process up to six foil webs in a
range of widths since 2007, resulting in cost savings of up to 50
percent, at IPEX 2010 Heidelberg will be presenting the world's
first cold foil module that supports indexing when transporting
In the past it has been necessary to cut off a length of cold
foil corresponding to the circumference of the blanket cylinder.
This is now no longer the case, as the foil transportation stops
when the foil can no longer be transferred onto the sheet, for
example when the foil travels over the gripper margin or the
cylinder gap. In other words the customer uses only the required
amount of foil for the sheet size.
The new FoilStar with index will be available for the
following presses from fall 2010: Speedmaster XL 105, XL 75, CD 102
and CD 74. The maximum print speed is 15,000 sheets per hour.
It is also possible to retrofit existing FoilStar modules
from 2007 and later (2nd generation) with the index function,
thereby harnessing these major cost and environmental benefits.
Based on an annual print output of 4 million sheets, for
instance, the new index function results in savings in foil
consumption equating to 133 tons of
. If the annual print output rises to 6 million
print sheets, the environmental benefit amounts to a cut in
of 200 tons.
Cold foil finishing - the technology for stunning effects
FoilStar applies the cold foil using two offset printing
units. In the first unit, glue is applied using the inking unit and
an offset printing plate either as a spot application or over the
entire sheet. The second, actual cold foil unit has take-up and
take-off units for applying the foil. Along with the sheet, it is
fed into the nip between the blanket and impression cylinders and
applied by pressure to the areas of the printing stock coated with
glue. When the substrate foil is removed, the metal layer remains
on the sheet. Subsequent overprinting of the foil allows users to
achieve a variety of color nuances. A further benefit is that both
printing units can be changed over rapidly and are then immediately
available for printing.
Existing FoilStar units can be retrofitted with
the IPEX premiere of foil indexing as well.
On the left you see the Standard FoilStar and on
the right the FoilStar with index function. It is visible that the
index function guaranties a foil usage without any interruption to
facilitate cost and ecological advantages.
