Datacolor has revealed its 45G portable spectrophotometer, which controls colour and appearance in complex manufacturing supply chains, producing measurement results that correlate better to visual assessment. For items with multiple visible components such as automobiles, achieving colour harmony is complicated by the need to visually match those components. For example, interiors have hundreds of visible parts that must visually match the appearance of the parts around them (think of all the buttons, knobs, switches, and air vents that are found in a car). Colour, textur2e and gloss all play a part in the total appearance of each of these parts, so a slight change in the pigment mix, a worn mold or the wrong mold temperature can result in an expensive partrejection by the customer. The Datacolor 45G portable provides repeatable measurements that mean consistent part production and the tight inter-instrument agreement ensures that digital standards can be shared throughout.
