Measurement | colour & masterbatch
Communication tools Another area of improvement is easier communica- tion between designers and labs for colour match- ing. “Customers expect that a compounder or masterbatch producer can offer quick turnaround for custom colour matching and can match any colour that they can dream up,” says CyberChrome’s Becker. “It’s getting to the point that they expect to take a picture of the colour they want on their smartphone and be able to send that over to the colour lab to get it matched.” A smart-phone camera only captures RGB data, not the full spectral curve needed to get the best colour match under all light sources, but the technology can give a ballpark match. “The biggest need is to give the designer of the original part a tool to specify colour that will deliver colour solutions based on end-use properties and durability at the lowest cost,” says Beck at Americhem, who points out that in some cases a designer will request a colour that simply isn’t possible to reproduce in plastic. These colour communication needs could be
satisfi ed by an entrepreneurial software application developer working with a relative newcomer to the
colour measurement industry, Variable. The latter’s Node+Chroma is a portable, wireless tool for communi- cating colour that was originally designed for the consumer space but is now fi nding application in a wide range of industries. These include the plastics supply chain from product designers for brands all the way back to compound and masterbatch producers, says Jonathan Bragdon, chief business offi cer at Variable. The Node+Chroma is a pocket-sized tristimulus
colorimeter that is integrated with a smart device – possibly a dedicated device but more likely the user’s smartphone or tablet – as the user interface. “The device extends the capability of colour communication to the front-end, sales side of the business,” says Bragdon.
