QuadTech to Introduce New Press Control Innovations at drupa 2012
The system captures 31 channels of accurate spectral color data from multiple patches of the color bar, with each image capture. The data, converted to L*a*b* and densitometric values, is then analyzed by System Brunner’s enhanced Instrument Flight + L*a*b* to facilitate the highest levels of accuracy in color control and gray balance. The system gives a better match between proof and print and automatically maintains optimal color throughout the run, compensating for any change in running conditions on the fly, irrespective of press speed.

QuadTech’s Register Guidance System with MultiCam is a closed-loop color-to-color register control system designed to work on the ICON integrated platform with other QuadTech products such as Ribbon Control System with MultiCam. The uniqueness of the MultiCam design is that it can search the entire repeat length of the web, identifying marks as small as 0.36mm (0.014 in). It can easily process the volume of data generated with a 640 x 480 pixel sensor using unique FPGA-based hardware. MultiCam makes adjustments at press speeds of up to 17,8 meters per second.
QuadTech’s Register Guidance System also provides fan-out control software, automatically keeping the system in lateral register across the width of the web. Other recent enhancements include cocking control, anti-embossing, and ink guiding capabilities.
These can then be linked to the ICON integrated platform, which provides real-time press control from a single point. Data Central Reporting, which is linked to the company IT system, generates and stores data as it is monitored, optimizing quality control for operators who can then compare productivity and make strategic decisions according to previous and live runs.
The newspaper industry is moving toward higher quality consistency in order to attract advertisers and build brand loyalty at a time when readers are faced with a growing number of alternative media options. As a result there is less tolerance of defects, especially in areas such as color reproduction and registration. QuadTech has formed strategic partnerships with several major newspaper publishers to overcome these challenges.
