Il Sole 24 ORE, the European economic and financial media group, has ordered three MAN Roland Regioman web offset presses, to be delivered in 2005.
Now the Roland 700 Hiprint and Roland 700 Directdrive models are taking over, the latter claimed to be the first available series-produced press worldwide with direct drive of the plate cylinders.
With the new developments in accordance with the company's value-added printing philosophy, Markus Rall added that MAN Roland is living up to the global trend towards production efficiency and increased product value.
Both model lines are said to be aimed at high productivity, integration of additional processes, quality safeguarding and value-added performances.
MAN Roland said that the new Roland 700 Hiprint stands for the continuity of high quality standards in conjunction with integrated coating and enhancing options.
Comparative calculations of make-ready times for eight-colour sheetfed offset presses commonly used today, versus those of an optimally equipped Roland 700 Directdrive, show that job change-over times can on average be reduced by as much as 60 per cent to less than 20 minutes.
It is claimed by MAN Roland that those results make the Roland 700 Directdrive the best press for make-ready time, with its main applications focused on runs of less than 5,000 sheets, or with use in rapid-fire printing of more than 10 jobs per shift.
The Directdrive system directly drives the plate cylinder.
In combination with a coupling system, it is claimed to enable simultaneous changing of all printing plates and simultaneous make-ready operations.
During a job change-over, plate changes in all printing units and blanket wash-ups are concurrent, the inking-roller wash-up is concurrent with blanket-cylinder and impression-cylinder wash-ups and can be done at different optimum speeds for the respective functions.
According to MAN Roland, individual inking units can be de-activated and image start can be corrected by up to 99mm.
The company added that Directdrive was thoroughly tested and in 1996 it had applied for first patents on the system in a sheetfed press because it had experience with direct drive from web offset printing.
In 2004, the first ROLAND 700 printed as an experimental press with direct drive, whilst ther system's presentation at Drupa 2004 was followed by field test installations and testing of the first Roland 700 Directdrive in the Offenbach factory.
Now, with the start of series production at the beginning of this year, MAN Roland believes the system is perfected and reliable.
On show at the Technology Forum were the Roland 700 Directdrive in a 10-colour configuration with in-line perfector and the Roland 700 Directdrive with six printing units and double coating.
The Roland 700 Hiprint was a six-colour version with Prindor in-line foiler and cold-foil enhancing.
The Roland 700 Hiprint's features include an increased sheet format of 740mm x 1,050mm, or 780mm x 1,050mm, which is claimed to be the largest print format in this class of machine.
The press's speed has been increased to a claimed 17,000 sheets per hour (sph) in optional straight printing and 13,000sph in perfecting.
The new Transferter is said to have been designed for better colour register and more precise setting of the gripper pad bars.
At the same time, the printing units can be de-activated in long designs.
The standard configurations of the Roland 700 Hiprint comprise the two-colour, four-colour and five-colour presses, as well as short perfectors for 1/1, 2/2, 1/4 and 2/3 printing.
The long configurations include the versions for 8-colour, 10-colour or 12-colour printing with the perfecting versions 4/4, 5/5 or 6/6.
Those configurations can be further equipped with a coating module, a swing-in coating system, in-line coater and smart or reel-to-sheet feeder.
The in-line configurations are said to encompass different versions of coating devices, including UV, cold-foil enhancing and in-line quality control systems.
In addition, there are a number of quick change devices for cutting make-ready time to increase productivity.
MAN Roland said that with those configurations, the Roland 700 Hiprint is an all-round press for use in all market segments, for all final formats, substrates and quality demands.
In addition to the claimed worldwide first electronic direct drive of the plate cylinders, the Roland 700 Directdrive offers various new developments in feeder and delivery and new features that reduce make-ready time.
They include an increased base height by 50 per cent to 834mm and increased pile load capacity by 70 per cent to 2.2 tonnes.
There is also new pile-lifting technology for doubled speed in raising and lowering, as well as for fine pile phasing, as well as a new suction head with a complete guard and new suction-head suspension with improvements in, for example, blast and separating elements, added MAN Roland.
Other features include new pile-edge scanning and new sheet in-feed control with automatic correction of early, late and misaligned sheets, together with a new control console on the operator side and a turnable in to various positions.
The new delivery of the Roland 700 Directdrive is a further development of the Airglide delivery.
It provides a new suction device for powder and odour and powder removal with suction at the delivery gripper, as well as a new dryer concept for modular lamp casings, observation of sheet travel and pre-installed waste-air tubing.
In addition, a claimed new concept has been developed for UV drying between printing units.
The new quick-action slide-in modules can be used as both interdeck and end dryers, added MAN Roland.
Almost 600 delegates from Europe, overseas and the Far East visited the week-long forum to experience B1-format sheet offset printing demonstrations.
