The QuadTech SpectralCam™ delivers L*a*b* data for precise, cost-effective colour management

QuadTech has entered into a new partnership with the Gallus Group to provide its closed-loop colour control and colour measurement systems for the group’s range of offset, flexo and gravure presses.

With QuadTech technology, Gallus customers can speed up make-ready and offer high print quality and productivity, with in-line colour management.

With a typical ROI of less than two years, the colour control systems are an essential consideration for many web printers looking to meet changing customer requirements and demands for high colour standards, with consistent repeatability from run-to-run and site-to-site. 

Dr Thomas Weber, supplier relationship management, Gallus, commented, ‘Gallus has vast market experience and the widest customer base in the label printing industry. However, we recognised the opportunity to partner with QuadTech to provide our customers with state-of-the-art spectral colour measurement and colour control systems, with the automation to drive further reduction in make-readies and savings in valuable substrate waste.’ 

The QuadTech Color Control System with SpectralCam provides automated, in-line, closed-loop colour control. On-the-fly and at full press speeds, it adjusts ink keys to maintain specified colour targets, preventing avoidable waste and operator inaccuracies.

Printers can also benefit from the QuadTech 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 colour specifications, eliminating press stoppages and the manual process of removing sections of the web to measure colour.

The ability to control colour on problematic substrates such as films has been a significant objective for the printing industry. The company has been able to solve this, by utilising its web stabiliser to remove common issues of web movement and substrate corrugation. 

The web stabiliser measures substrates over a certified BCRA ceramic tile, for a constant known backing, and momentarily stabilises a small surface area of the substrate with a high pressure vacuum. This allows accurate colour measurement on very thin, transparent and translucent films – ideal for self-adhesive labels, monofoil labels, wet-glue and laminates.

Stephan Doppelhammer, QuadTech market manager for packaging, said, ‘Gallus and QuadTech are perfectly aligned in the drive to create solutions that maximize customer benefits and profitability. We are delighted to offer a faster way for Gallus customers to achieve and maintain perfect colour, for guaranteed high-quality output, optimal performance, cost savings and fast ROI.’
