Cortina

Compact waterless newspaper offset presses – a landmark innovation

The Cortina’s diminutive form conceals revolutionary technology for making colour newspaper and semi-commercial production greener, leaner and more cost-effective: the press is not only waterless, but keyless and gearless into the bargain. A benchmark feature of the Cortina is its robust and reliable PlateTronic automatic plate-changing system, which has proven its efficieney a hundred times over a day-to-day operation

Just one
operating level

Maximum rated output 80,000 cph

Available in three versions: four plates wide and one or two around, or six plates wide and two around

A height of around 4 m for a four-high tower facilitates handling and allows installation in standard industrial buildings

Waterless, keyless inking units minimise waste, eliminate fan-out and promote a uniform print quality with little or no manual intervention

Space-saving, user-friendly design

Gearless, oil-free printing unit with dedicated AC drive for each cylinder supports flying plate changes and integration into computer-to-press systems at a later date

Eight-high tower version (height approx. 9m) makes flying imprint changes in 4/4 production more cost-efficient than ever before

StepIn tower splits down the centre to afford easy access for maintenance tasks

Engineered to reduce emissions (less waste, no dampening, no oil lubrication)

Orders for 4/1, 4/2 and 6/2 versions have been placed by printers in Belgium, Denmark, Finland, France, Germany, the Netherlands, Switzerland and the UAE

The Cortina successfully marries waterless offset with newspaper production. Dispensing with dampeners, in conjunction with our keyless inking system (Newsflow), can substantially enhance cost efficiency while delivering a uniformly high print quality. The large proportion of Cortina users who were accepted for membership of the Ifra Color Quality Club is indicative of waterless offset’s considerable quality potential.

Benefitsof waterless offset:

Minimum waste, less paper consumption

Better, more consistent print quality (less dot gain, 60lpc screen, FM screen)

No problems with web tension

No dampener, no water additives

No problems with ink/water balance

No fan-out, even on wide webs

Easy, labour-saving operation

High-speed changes between coldset and heatset (with dryer)

Enhanced ecology

The unique, space-saving design of a Cortina four-high tower, which at just 4m (13ft) has only one main operating level, expands your options with regard to investment planning, edition splitting and handling.

Little or no investment needed in new buildings

Lower capital investment costs for press and infrastructure

Lower running costs (heating, cooling, maintenance etc)

Easier handling, just one main operating level

Module-based design allows maximum utilisation space

Eight-high tower with straightforward vertical web lead allows flying imprint changes in 4/4 production e.g. at Edipresse in Lausanne, Switzerland

Four-high towers for 4/4

Size for size, the Cortina has a much higher pagination and colour capability than conventional tower presses. On top of this, its modulebased system supports a wide choice of configurations to accommodate space constraints, with the 6/2 version delivering the biggest savings. Press lines include coldset, heatset and hybrid versions.

The Cortina's modular design allows configurations to be customised to suit presshall architecture and the space available

The Cortina is available in three versions: for four plates across and one around; four across and two around; or six across and two around. It has a maximum rated output of 80,000 copies per hour in straight-run production.

Rapid plate change

Semi-automatic plate changing with pneumatic plate clamping shortens makeready and eases handling

Optional automatic plate changing cuts changing time for one or all plates to around two minutes, reducing manning requirements for edition changes

Tower unit splits down the centre to afford easy access for cleaning and maintenance work, eg blanket changes

KBA RollerTronic automatically adjustable roller locks, KBA NipTronic bearing units and KBA CleanTronic integrated blanket washing reduce maintenance and ensure a uniform print quality

KBA TemperaTronic controls promote a consistently high print quality by maintaining a uniform temperature in the plate cylinder and anilox roller

KBA Plate-Ident automatic plate-recognition system guarantees error-free plate allocation

The StepIn tower slides apart for easy access and maintenance

The short cut to quality 4/4 colour

The Newsflow keyless inking units on the Cortina are specifically engineered for waterless web offset printing at high speeds. The Cortina is the world’s first coldset newspaper press with the ability to print a 60lpc (150lpi) screen or FM screen as standard, though conventional screens are also possible. Ink is pumped to the plates continuously, irrespective of ink coverage, via a doctor blade4, an anilox roller and two ink-forme rollers. Two oscillating distributor rollers and two additional inking rollers ensure a perfectly smooth ink film. Emulsification – a familiar problem in conventional offset – simply does not occur with the Cortina.

More uniform colour reproduction, less waste when printing split editions

More standardised production, fewer variables

No operator-related fluctuations in inking

Temperature control for optimum print quality

Optimum reproduction of quality defined in pre-press

Press presetting reduced to a minimum

Units can be swung down pneumatically for easier access

No ink misting at high press speeds

A Cortina featuring a dryer for printing heatset copies with no change of ink is in operation at De Persgroep’s printing plant in Belgium

Coldset, heatset or both – with no change of ink

One of the Cortina’s unique properties is its ability to print coldset and heatset products, or a combination of both, with no ink change and no fan-out whatsoever.

The Cortina’s innovative turner-bar deck is as compact and ergonomic as the rest of the press. Short ribbon paths and convenient operation make for fast edition changes, while the absence of ink keys and dampeners is a big advantage when handling webs of different widths.

More convenient operation and less manual intervention, eg thanks to chain web-up system

Shorter web leads

Choice of performance-proven KF3 or KF5 folder

The space saver

The cylinders, inking units and other subassemblies in the Cortina printing units have dedicated shaftless AC drives for gearless, oil-free operation. The press boasts a high level of automation throughout, controlled from a console featuring top-spec KBA technology.
