The company will demonstrate how its colour control, web inspection, register control and data management systems help newspaper printers significantly reduce waste and boost quality at the expo in Vienna, Austria from 10-12 October, 2011. Its latest technology advancement combines industry-leading colour control and web inspection, all from the same sensor.
The Colour Control and Web Inspection System with AccuCam utilises a proprietary 6-channel spectral sensor for Lab-based colour control – eliminating the need for colourbars or graybars. This closed-loop system analyses the entire image and automatically obtains target aim point values from a high-resolution prepress file to maintain accurate colour by automatically adjusting ink keys.
The system also automatically controls and optimises the ink ratchet for superb inking performance, creating better colour, reduced waste and minimized operator intervention. All surfaces are inspected and common print faults such as scumming, blanket smashes, incorrect plates, and colour variations are detected.
The system has been installed at a number of high-profile newspaper printing operations in the last 12 months. Five towers are being installed on two manroland Colorman XXL presses at Herold Druck und Verlag AG, based in Vienna, Austria.
In Japan, Sankei Shimbuns Hokusetsu (Osaka) plant has also used AccuCam on 16 towers to achieve NSAC-standard colour. The plant is now producing the best colour quality in the Sankei group, and has established the colour standard for all Sankei plants to meet. AccuCam was launched after successful trials at the Newsprinters Knowsley (UK) plant, which prints national News International titles such as the Times, the Sunday Times and the Sun.
The companys MultiCam has provided accurate colour-to-colour register, cutoff register and sidelay register to newspaper and commercial web printers in over 100 countries. With over 10 000 cameras installed, MultiCam is the worlds best-selling register camera.
The Ribbon Control System with MultiCam is a closed-loop, print-to-cut and print-to-fold registration system that uses two types of compensating devices to control registration: cutoff compensators control print-to-cut registration to minimise cutoff (circumferential) error, and sidelay compensators, such as angle bars, control print-to-fold registration to minimize sidelay (lateral) error.
Register Guidance System, which includes the MultiCam camera, has been enhanced with automated features such as fan-out control and front-to-back register control. The companys fan-out control software automatically keeps the press in lateral register across the full width of the web, throughout the entire run. Register control cameras mounted on both the gear and operator sides of the web capture tiny shifts in lateral register and instantly make automatic corrections via an interface with the bustle wheels.
Karl Fritchen, President of QuadTech, said, Our press control technology is engineered to allow printers to achieve uncompromising quality consistency. For printers interested in employing lean production methods, our innovations can be instrumental in reducing waste and minimising operator involvement. This has been recognised by major players in the newspaper print industry who have improved their bottom line thanks to both the performance of the technology, and the first-class, global, round-the-clock service guaranteed to all QuadTech customers. IFRA-Expo 2011 will be the perfect opportunity to discover these benefits firsthand.
