The Competitive Edge III - Inline Die Cutting
In part 3 of our series we will explore the increasing demand to
finish printed products inline.
As print users continue to pressure producers to turn printed
work around faster, can print shops afford to use traditional
creasing and die cutting methods on the Heidelberg cylinder work
horse?
Yes, the cylinder has been a cornerstone of all print shops
for many years, but with an average running speed of under 4000sph,
and press running speeds at 15,000sph, we have a productivity
bottleneck that needs to be addressed.
One of the methods being used by some shops today is to
crease and die cut in-line using a printing unit.
By replacing the blanket with a base plate and fitting a
special jacket to the impression cylinder, (which the printer makes
offline by fitting fine blades via a grid for creasing or cutting),
considerable time savings can be achieved. The press can now be run
close to normal printing speeds while removing the need for double
handling once the sheet is printed.
There are several companies offering systems that can be
fitted to a printing unit up to A1 format. Heidelberg offers one of
these systems - RSP from Cito.
Another way to crease and die cut inline is by use of a
dedicated inline die cutting tower. Heidelberg offers in its
Speedmaster SM52 range of presses a dedicated tower which allows
for inline creasing and die cutting. It also has a vacuum waste
extraction so cuts can be extracted on the run. The tower has two
steel cylinders, one is magnetic were a metal plate is attached,
and an opposing plate is fitted to the other. Production speeds in
excess of 12,000sph can be reached thus drastically reducing
production times.
Still wanting Off-Line Die-Cutting?
Setting new standards for off-line die cutting is the new
cost effective Varimatrix 105 CS available from Heidelberg. The
Varimatrix is able to cut, crease and automatically strip the waste
in sheets from 80gsm up to 4mm thickness. Its ability to handle a
maximum sheet size of 750 x 1050mm, high running speed of 7500sph
and its ability for rapid job change makes it ideal for short runs.
So are the days of the Cylinders coming to an end….?
