repetitive process of having to calculate the right amount of each additive with each new formulation. Match Pigment comes into play in predicting the right formula.”


The software eliminates two bottlenecks. Firstly, in


the laboratory, it ensures that the initial calibration of the entire mixture for colour and opacity are correct. “The user still needs a good grounding in colour physics, but the software makes the procedure much easier,” Verma says. Secondly, for formulation work, it provides assis-


tance in choosing the right balance of additives, using Datacolor’s SmartMatch technology. “Once you have tuned the system, it gives a proven formulation you can trust, based on previous successful formulations.” There were several new colour measurement


offerings on show at NPE 2015 in Orlando earlier this year. Konica Minolta’s Colibri Color Management Suite software, for example, consists of four modules for specifying, formulating, evaluating, and managing product colour across the supply chain. According to Dan Randall, director of sales at Konica Minolta Sensing Americas, its intuitive platform and compre- hensive features make it easy to define and share product colour specifications, match and correct colours, monitor measurement data at each facility in real time, and coordinate colour seamlessly from design to manufacturer to finished product. X-Rite unveiled what it termed “next-generation”


colour management solutions, including the Ci7800, a “master-level” bench-top sphere spectrophotometer, and the slightly lower-specified Ci7600 model. They are said to feature very high stability over a range of environmental conditions for opaque, transparent and translucent materials. The new design makes it easy to use, configure and


service in the field, X-Rite says. When used in conjunc- tion with X-Rite Color software, the devices can adapt to fit into any colour supply chain, automatically adjusting instrument settings, tracking measurement require- ments and recording images of each sample. The units feature an on-board camera


X-Rite’s Ci7800 features an on-board camera to


provide a visual record of every sample


that captures images of each measurement, providing a visual record of every sample as well as a detailed audit trail of the settings at the time of measurement. On-board sensors capture temperature and humidity at the time of measurement. They come with five reflectance apertures and four transmission apertures

(three for the Ci7600), and three automated UV filters for increased measurement flexibility across opaque, transparent and translucent materials. HunterLab, meanwhile, says it is working on testing


a new non-contact technology for measuring colour on large, irregular shaped samples of any type, including plastics pellets and recycled flakes. “It looks promis- ing,” says European sales manager Christian Jansen, while noting that the company is not yet in a position to provide details beyond the fact that the instrument to be used is the company’s D25 NC.


In-line measurement At NPE, Konica Minolta also demonstrated its NC-1 in-line colour monitoring and control system, which it says is its most advanced system because of its automated measurements and ability to deliver real-time measurement data. The NC-1 is capable of measuring the colour and


appearance of opaque, translucent, and transparent products with smooth or textured surface conditions. It is said to be particularly effective in measuring solid colours and multi-coloured materials with variegated, mar- bleized, or streaked surfaces. However, this is aimed at producers of finished moulded and extruded products (it cites vinyl siding as one example), and does not currently appear to be configured for use by com- pounders. X-Rite on the other hand has


been offering an in-line colour measurement system for compounding lines for several years. Manfred Binder, marketing & sales director with the company in Munich, Germany, says the original ERX50 was replaced last year by the ERX130, which has 10
