Printing and coating in a single pass
Heidelberger Druckmaschinen AG (Heidelberg) has unveiled a
new coating system for the Speedmaster SM 52. This new development
follows the market trend for higher quality print products and
means that customers can now also process quality commercial work
in A3 format.
The Speedmaster SM 52 from the print and publishing solutions
provider gives users a vehicle for accessing the advanced
technology of large-format presses plus a high level of automation
in the 35 x 50 format segment. The worldwide market launch of the
new coating system complements the quality inline coating facility
of the rest of the Speedmaster series.
For four and five-color models, the coating system is also
available on perfecting machines of the Speedmaster SM 52. This
allows the printer to perform printing and coating in a single pass
and thereby reduces production times. This benefits businesses
focusing on quality commercial products in the 35 x 50 market.
Industrial companies using the Speedmaster SM 52 primarily as a
production tool for the growing number of small-run jobs will also
benefit from the new technology. The maximum print speed of 15,000
sheets per hour is matched by the coating system. The coating
system can handle printing stock up to a maximum thickness of 0.4
Heidelberg expects to have installed more than 25 Speedmaster
SM 52 presses with coating systems before drupa 2000. The USA and
Europe are regarded as the main sales markets, each accounting for
30 percent of sales.
A coating unit with a difference
The heart of the new coating system for the Speedmaster
SM 52 is a coating unit consisting of coating blanket cylinder,
coating pan, water pan roller and metering roller. What is so
special about this system is that the coating unit can be raised
250 millimeters out of the production setting into a
'parking' position. This ensures the sheets run smoothly
when printing without coating. It also ensures easy access when
changing the coating plate/coating blanket or when performing
cleaning work. This cuts make-ready times considerably.
The speed of the water pan roller, the contact pressure of
the metering roller on the coating blanket cylinder and the preset
adjustment of the printing pressure can all be controlled easily
and effectively via the CPTronic. The speed-compensated water pan
roller ensures the coating is applied consistently at different
production speeds. An ultrasonic sensor monitors the level in the
The lateral, circumferential and diagonal register is
adjusted by means of the register control facility at the CPC
control unit. The double-sized transfer and impression cylinders
ensure smooth and easy sheet travel.
The complete coating system package includes an extended
high-pile delivery which accommodates Heidelberg's DryStar
dryer combination in plug-in technology. This consists of an IR ink
dryer with four IR lamps and a coating dryer combining hot air and
IR. Water-cooled sheet guide plates are located below the dryers.
Heidelberg can now supply a new coating system for the
Speedmaster SM 52. Printing and coating can be performed in a
single pass, thereby greatly reducing throughput times.
