Product Description

The Solna C800 is a highly sophisticated and automated, commercial web offset press. It is designed for production of high quality magazines, brochures, directories, books and other commercial printing on uncoated and coated stock for a maximum speed of 40,000 rph depending on the equipment of the press and the produced job. If for tabloid product, it can print maximum speed 80,000 sheets per hour.

 

The press is equipped with a number of high-tech features for improved flexibility and productivity. Each perfecting unit is individually driven (shaftless) by Rexroth Indramat servo drive motors.The ink fountains have motorized ink zone adjustments remotely controlled from the operator console. The circumferential and lateral plate registers are motorized and adjustments are carried out remotely from the operators console. Plate and blanket cylinders are running without bearer contact (MultiRange System). Fine adjustments can be made to compensate for changes of stock thicknesses without disrupting the correct relationship between the cylinders, this guarantees ideal dot transfer.
 

The Solna C800 is designed to run with lowest operating costs, lowest waste costs and with a minimum of manning. The automatic plate positioning and plate lock-up guarantees shorter start-up times and exact plate mounting while the paper web remains in the press.

The Solna C800 is available in several press layouts for up to twelve units per installation. They may be placed in line, stacked or as a duplex arrangement of parallel lines. Production units are built for the normal left-to-right operation, but mirror-imaged units are available for right-to-left operation into, for instance, a central folder in a tandem layout.

For the Solna C800 there is the following folder concept available:

 

Folder F840: a full combination jaw folder in the ratio 1:2:2 ( with an optional double parallel fold)

Part of the Solna C800 is also the Solna DPC Printing Process and Control System. This is a highly advanced system that gives total control of both the process and print quality. The system is based on the market available standard components, which gives the possibility to integrated equipment and systems from other manufacturers like for instance register, color control systems and connection to pre-press systems (CIP3).

The design philosophy of Solna is to base as much as possible on standard components. The result of this is higher availability of spare parts, easier service and a longer lifetime of the individual parts. We work in close partnership with the main suppliers of all the necessary additional equipment such as: splicers, dryers, process control systems, ink supply systems, roll handling systems and climate control systems offer full advantage of Solna's C800 concept and to assure a high and even production quality.
