INSTRUMENTATION | COLOUR MEASUREMENT
Right: Konica- Minolta’s CM-26dG portable spectro-
photometer supports
simultaneous measurement of colour and gloss
All models enable fully digital colour manage- ment (no physical colour standards are required). Inter-instrument agreement (average for 12 BCRA colour tiles) is said to be within ΔE* 0.12 for the CM-26dG and CM-26d variants, an improvement of around 40% from previous models. The instruments are also equipped with the company’s Job Function feature, which allows measurement instructions (including photographs) for routine tasks to be registered in the instrument. This is said to improve process accuracy, productivity and consistency where the portable devices are likely to be used by several different operators. Frankfurt, Germany-headquartered Techkon, which makes colour measuring devices and software solutions for quality control, says its SpectroDens series makes colour measurements quick and easy. The instruments are claimed to solve the problem of measuring and matching colours on various substrates and surfaces. Beside its one-second measurement time and high accuracy, the SpectroDens device offers customers the option to measure with standard light condi- tions by supporting all measuring conditions inclusive of M1.
Low cost option A relatively low-cost alternative to spectrophoto- meters or manual control with light cabins comes from Swiss company Colorix. Its Colorcatch Nano is listed at €445 before tax, fits in the palm of the
hand, and connects with an app on a separate device. The product is mostly intended for quality control on printed images or coloured finished
materials of various types but, because it measures
areas as small as 0.3mm across, it
can also be used to measure colour of individual plastics granules. The Colorix app displays the CMYK, Lab, Lch and sRGB values, as well as the deviations for each. Set tolerances can be checked within one click, and information can be exported and sent in just a couple more. Colorix says the Colorcatch Nano is the only colorimeter in the world equipped with a camera that can be connected to a smartphone, tablet or PC. It does not take a photo, but films the surface and captures up to five colours simultaneously. A version sold by RAL shows the filmed colour or colours, finds the next RAL colours, and displays the technical specifications.
