At drupa 2004, Heidelberger Druckmaschinen AG (Heidelberg) will be
presenting the Suprasetter range, a new generation of thermal
external-drum platesetters. All parts of this device have been
developed by Heidelberg and it supports all Heidelberg plate
formats for sheetfed and commercial web offset. The Suprasetter is
available in 4-page and 8-page formats and is equipped with a new
Heidelberg laser imaging system. With five different speeds,
various automation settings from manual to fully automatic and a
high-performance system with Multi Cassette Loader (MCL), the
Suprasetter sets new standards in the prepress sector. The
Suprasetter features an end-to-end modular concept that provides a
great deal of investment security. Users have access to a wide
variety of add-on options which meet all their needs while at the
same time remaining flexible for subsequent adaptations.
"Heidelberg's extensive experience gathered over the
course of several thousand CtP installations has been put to use in
the development of the Suprasetter range. Many customers are
looking for a cost-effective gateway to CtP coupled with the
flexibility for subsequent system expansion. Our new Suprasetter
range is the ideal solution for these requirements. The many
innovations featured in the unit also give customers a crucial
competitive edge," explains Dr. Klaus Spiegel, member of the
board and responsible for products and marketing at Heidelberg.
The customer benefits of the Suprasetter range in detail:
Wide format range for the printroom
The Suprasetter (supra (Latin) = on the top, above, over)
supports all standard plate formats. The Suprasetter 74 is
compatible with all Heidelberg presses and many presses from other
manufacturers, from the Quickmaster QM 46 to the Speedmaster CD 74.
Additionally the Suprasetter 105 images the printing plate format
of the new Speedmaster XL 105 and web offset presses. The option of
imaging with centered or edge register integrates plate production
into the web offset process.
Scalable concept for different throughput requirements
The Suprasetter offers a wide range of plate throughput
options. The more laser modules a Suprasetter contains, the greater
its imaging speed. Additional laser modules can also be retrofitted
rapidly on site after the unit has been installed. In the S version
with two laser modules, the Suprasetter 74 images up to 19 plates
per hour, while the H version with four modules produces up to 30
plates per hour. In 8-page format, the Suprasetter E105 images up
to 14 plates per hour with two laser modules and the Suprasetter
S105 images up to 19 plates per hour with three laser modules. With
six laser modules, the Suprasetter H105 images up to 30 plates per
hour. These five models in total support many different
requirements and levels of automation.
Intelligent security systems for a stable production process
The laser modules in the Suprasetter feature an intelligent
diode system (IDS). If a diode fails, the system automatically
identifies the greatest string of active diodes to the right or
left of this diode. The production can then be maintained using
these active diodes. The large depth of focus of the Suprasetter
compensates for any unevenness in the printing plates. The
Suprasetter therefore ensures precise, constant imaging quality at
all times. A permanent temperature control system evens out
variations in the ambient temperature. It maintains both the
individual laser heads and the plate drums in the Suprasetter at a
constant temperature, so that imaging can be performed
independently of the ambient temperature and always under the same
conditions.
Efficiency through parallel processes
The Suprasetter separates what were previously sequential
process steps, thereby reducing throughput times. Productivity is
increased thanks to the swivel table with loading and unloading
levels that allow parallel loading, imaging, punching and unloading
of plates. By adding more laser modules the pure imaging time is
reduced. With plate handling times remaining constant this results
in a higher total throughput. For the internal punching system, up
to three pairs of punches are available in the Suprasetter 74 and
up to four configurations in the Suprasetter 105. In automatic
mode, the imaged plate is delivered to the processor in portrait
format which allows a thinner developer to be used. This saves on
space, chemicals and costs.
One automation concept for two families
The Suprasetter and Prosetter CtP series have an end-to-end
modular design which allows them to grow with the customer's
requirements. The automation components are the same design for
both imagesetter ranges. The manual basic units of both these CtP
series can be extended and the system as a whole expanded simply by
adding a Single Cassette Loader (SCL) or Multi Cassette Loader
(MCL). The Single Cassette Loader performs the loading operation,
then transports the imaged plate via an integrated conveyor to the
online processor for development. The SCL ensures automatic removal
of the interleaving sheet and stacks up to 400 sheets in an
integrated collection tray. For more flexibility and automation
when using multiple formats, the system can be expanded with the
new Multi Cassette Loader. This consists of the SCL and a Multi
Cassette Container holding up to four cassettes. Each cassette
can be loaded with up to 150 plates. The Multi Cassette Loader
therefore holds a total of up to 600 printing plates ready for
fully automated plate production. A software-controlled system in
the Multi Cassette Container automatically loads the appropriate
cassette for the required plate format into the SCL. This reduces
machine downtimes because cassettes can be exchanged in the Multi
Cassette Container while imaging is underway. The installation
outlay for additional modules is minimal and installation is
performed on site.
Smart Plate Handling ensures flexibility
In many companies, economic success also depends on the
overall processing time for jobs. Flexibility is therefore
particularly important for jobs that lie outside the normal
process. In plate imaging, this could be an unusual plate format, a
different type of plate or a plate that needs post-imaging. The
Suprasetter therefore provides an intelligent concept for flexible
handling of printing plates. Unlike competitors' systems, in
the automated version with SCL or MCL the loaders are docked onto
the reverse of the imagesetter, allowing the plates to be manually
loaded and unloaded. This means the manual plate shaft on the front
of the Suprasetter remains freely accessible. A rarely used format
can therefore be still loaded manually into the Suprasetter thanks
to the Smart Plate Handling concept. Depending on requirements,
these plates are either transported automatically into the online
processor or output again undeveloped via the plate shaft at the
front. This system gives users the automation they need while still
allowing the necessary flexibility for working with more than one
plate format.
Plate on Demand for the printroom
The new "Plate on Demand" function integrates all
current Heidelberg CtP devices (Suprasetter, Topsetter and
Prosetter) even more efficiently into the pressroom. To use this
function, the operator of the Prinect CP2000 Center does not even
need any prior knowledge of the prepress processes. He simply
selects the required job on his touchscreen. At the touch of a
button, he then starts the plate imaging for the required color
separation or the entire job directly via the CtP device. This
direct control of plate production is particularly useful during a
night shift or for post-production of a printing plate. The
prepress operator prepares the jobs as before, the press operator
can then look at the job list and if necessary change the order of
the jobs later on or select to go directly to the imaging stage by
pressing a button on the CP2000 Center. This means the capacity
utilization in the printroom determines the plate production from
the outset rather than vice versa. The "Plate on Demand"
function will be available at the end of the year. Users must have
Prinect MetaDimension Version 5.0 and enable the Preset Link option
in the Prinect CP2000 Center Version 41 or Prinect Print Center.
