Solna C800
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 max 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 (MultiRangeSystem). Fine adjustments can therefore be made to compensate for changes of stock thicknesses without disrupting the correct relationship between the cylinders. A guarantee for 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 is guaranteeing shorter make ready 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 open and based on the market available standard components, which gives the possibility to integrated equipment and systems from other manufacturers like for instance register, colour 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 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 in order to offer full advantage of Solnas C800 concept and to assure a high and even production quality.

Drive & Control System
Drive System
The Solna C800 has a shaftless drive system with servo drive motors of Rexroth Indramat. Each printing unit and folder as well as splicer, infeed unit and,chill-roll stand are equipped with a single servo motor.
Control System
All functions of the Solna C800 are controlled by the Solna Printing Process Control system (PPC) and consists of the following parts as standard:
- 2 Operating consoles DPCIII with PC computer and software, video screen with alarm display and sequential start/stop to run the main press functions and the remote-controlled ink fountains, plate registers and dampening systems.
- 1 Press Master Console for connection to RIP or CTP-system, set-ups and supervision.
