Is inline colour measurement the key to total production control?

The new high speed colourCONTROL ACS7000 system from Micro-Epsilon can continually monitor a production process ensuring that all manufactured items are within desired colour tolerances. It not only recognises reference colours by comparison, but identifies individual colours clearly from their coordinates in the colour space.
Ideal for packaging, print, cosmetics, textiles, food production and much more.

The new colorCONTROL ACS7000 colour measurement system identifies colours using any of the XYZ; L*a*b*; L*u*v*; RGB and DIN99 measurement definitions (user selectable). The system can be set up to continually monitor a production process and output the colour measurement via Ethernet, EtherCAT or RS422 and can also be taught pass fail/limits and then output out-of-tolerance alarms using digital I/O.

The system is suitable for a wide range of applications where colours and shades must be examined on-the-fly and to very high accuracies. Existing applications include automotive paint inspection, colour measurement of car interiors, coloured glass, transparent film and sheet production, printing, packaging, medical technology, food, cosmetics, pharmaceuticals and in the processing of plastics, food, wood, paper, veneer and textiles. The system is equally suitable for offline R&D laboratory applications.

True colour measurement is required in many industry sectors, enabling companies to select, monitor, grade and sort various types of coloured objects involved in manufacturing, automated handling, warehousing, packaging, wrapping and other production processes. Measured objects can take the form of solids, liquids or transparent surfaces such as coatings or labels, as well as LEDs or lamps.

Chris Jones, Managing Director at Micro-Epsilon UK comments: “The accuracy of most inline colour sensors in the marketplace are typically defined with a ?E of 1-1.5, which represents similar performance to the human eye. However, as the ACS7000 uses a spectrometer for colour measurement/evaluation, its performance is typically a ?E of 0.1, which is 10 times greater! This enables users to solve applications that were previously not possible. With the ACS7000 having a measurement speed of up to 2kHz, it is now possible to integrate the system into the production processes, improving automation, quality control, production efficiencies and product quality, whilst also reducing operational costs and waste.”

The colorCONTROL ACS7000 series has a choice of three different sensor families: the ACS1, ACS2 and ACS3. Designed for different measurement tasks, each family has specific optical angles, spot geometries and focal distances.
