The QuadTech SpectralCam delivers L*a*b* data for colour management
USA • QuadTech announced a new partnership with the Gallus Group (St. Gallen, Switzerland), to provide QuadTech closed-loop color control and colour measurement systems for its offset, flexo and gravure presses.
QuadTech colour control systems have a typical ROI of less than two years. Dr. Thomas Weber, Supplier Relationship Management at Gallus comments, “Gallus has vast market experience and the widest customer base in the label printing industry. However, we recognized the opportunity to partner with QuadTech to provide our customers with state-of-the-art spectral color measurement and color control systems, with the automation to drive further reduction in make-readies and savings in valuable substrate waste.”
Designed for offset printers, the QuadTech Color Control System with SpectralCam provides automated, in-line, closed-loop color control. On-the-fly and at full press speeds, it adjusts ink keys to maintain specified color targets, preventing avoidable waste and operator inaccuracies.
Flexo and gravure printers can also use from the Color Measurement System with SpectralCam, which enables in-line monitoring of all packaging substrates, including challenging translucent, transparent and reflective films. Colour variations are sent to the operator in real-time to change color specifications, eliminating press stoppages and the manual process of removing sections of the web to measure color.
The ability to control colour on problematic substrates such as films has been a significant objective for the printing industry. QuadTech utilizes a web stabilizer to remove common issues of web movement and substrate corrugation. The web stabilizer measures substrates over a certified BCRA ceramic tile, for a constant known backing, and momentarily stabilizes a small surface area of the substrate with a high pressure vacuum. This enables accurate colour measurement on very thin, transparent and translucent films – suited for self-adhesive labels, monofoil labels, wet-glue and laminates.
QuadTech introduced the technology to the Gallus’s worldwide sales force during the world sales meeting and will showcase the SpectralCam systems at Gallus Innovation Days, September 23rd-25th 2014.
