Key Benefits
• Quality
Cobra's imaging quality is superb with its powerful
60mW violet laser. Its precise optical system is
capable of imaging with screening resolutions of over
175 lpi, giving excellent results on plate.
• Speed
The wait for plates is over with Cobra's high speed
spinner, designed for fast imaging. Combined with
easy plate handling, this enables Cobra 8 to output
up to 16 plates per hour, including plate load/unload
time.
• Reliability and Accuracy
Cobra 8 uses a high precision internal drum and violet
laser technology – a combination proven to give the
most reliable and consistently accurate imaging on
metal plate.
• Affordable Performance
Cobra's low cost of ownership and competitive return
on investment results in one of the most affordable
CtP systems on the market.
• Ease of Use
Cobra's plate management console software has been
written specifically to make platemaking easy – it is
so simple that anyone can use the system to produce
plates quickly and reliably.
• Versatility
With its standard USB 2.0 interface, Cobra 8 can be
connected to any suitable Windows PC RIP that
outputs 1-bit TIFF bitmaps. This fast industry
standard connection ensures that Cobra is a truly
“open” system.
• Future Proof
Cobra 8 is capable of imaging all silver and
photopolymer violet plates currently on the market, to
give a wide range of plate options both now and into
the future.

Cobra 8 is a manual load-unload CtP engine designed
specifically for the B1/8-up commercial print market.
It exposes violet metal plates at high resolution, using
high precision internal drum imaging optics and a
60mW laser.
The pre-punched plate is placed directly into the drum
by the operator, and located in the U notch
registration system. Vacuum is then applied to hold
the plate in perfect register while it is imaged at a
resolution of 2540 dpi (100 dpmm) at a speed of 6mm
per second. An 8-up B1 plate takes only three
minutes to image, regardless of content.
The Cobra 8 system includes a high-spec workstation
running a Torrent PS RIP, with a full complement of
software applications that enables rapid processing
and output of jobs to the Cobra 8.

Registration Configurations:
Cobra 8 has a U notch registration bar to accept prepunched
plates, where the 425 mm notches can be
switched in or out. There are two options of register
system:
standard 780 mm and standard 425 mm;or
standard 830 mm and standard 425 mm
making it suitable to image B1, B2 and B3 (landscape
format) plates.
User Interface
A new Java based user interface for ‘point and click’
plate production has been specifically designed for
Cobra. With ‘at a glance’ multiple views, a home view
showing previews and status of current jobs, overviews
of all queues and completed plates, it is a powerful
and highly effective tool in the plate production
process. (See screen shot, bottom right.)

Making CtP work for you
The benefits of using Cobra 8 in your workflow are
compelling. Its quality and speed of output let you
produce plates to meet the ever increasing demands of
today’s print shop. Cobra’s simple and clever design,
with remote diagnostics, ensures an extremely high
level of reliability with minimum downtime. This will
put you ahead of your competition in the quest to
satisfy your customers' high expectations.
Combining all these benefits with low cost of
ownership, Cobra provides affordable metal plate
production with an excellent price/performance figure.
Additional features such as CIP3/4 ink-key setting and
ROOM proofing help to ensure an investment geared
for long-term success.
Using HighWater’s Barcode ID software, which
generates a unique identification mark on the plate,
users can easily retrieve jobs for re-making plates.
