Previously ICI Imagedata relied on visual inspection of the moving ribbon, combined with spot measurements on random samples on completion of each three-kilometre roll. Now, using the AstraNet spectrometers, quality is continually monitored at the end of the production line across the whole width of the web. Mike Mills explains why this was a particularly complex project, ‘This was the first time we had designed a solution using multiple spectrometers linked to a single PC. The PC also had to be networked to enable managers to monitor and analyse quality information remotely, without having to enter the controlled environment of the manufacturing area. ICI Imagedata now has a powerful, versatile monitoring system which delivers greatly enhanced quality control for its dye sublimation printing ribbons.’

AstraNet Systems Ltd, a specialist supplier to the UK and European UV spectroscopy and radiometry markets, is highly skilled in system integration. Application problems ranging from simple lab-based measurements to fully integrated systems for on-line measurement and control are solved by combining the right instrument, accessories and software.
