Sensing has launched the CM-17d portable unit which is
designed to provide higher accuracy measurement in a shorter measurement time
Instant CMYK, Print Density, RGB and HEX, and has M0, M1, and M2 measurement nodes that can be used with optical brighteners, Uress said. The system is compatible with a range of colour systems, such as Pantone from X-Rite, the Reichs- Ausschuss für Lieferbedingungen (RAL) colour coding system from Germany and the Natural Colour System (NCS) developed by the Swedish Colour Centre Foundation. To operate, users place the Spectro L on the surface to be measured, press the “Scan with Nix” button on an app running on their mobile device. Nix Spectro L can complete a scan in 2.5 s, provid- ing the captured data in a 10nm output, Uress said. ACT also recently developed DeltaEZ, an app for mobile phones and tablets that allows the Nix Spectro L user to create, add to and modify their own cloud-enabled colour library. Users can view a list of recent measurements added to the colour library, organise the colour targets, save the measurements or set filters to find specific measurements for compari- son or trending and statistics. The DeltaEZ app also allows users to initiate lighting simula- tions where the colour difference between a standard and a sample can be evaluated with the device compared spectral data to determine acceptability. A 3D visualisation feature allows users to observe differences in lightness, chroma and hue in 3D space, as well as rotate, zoom, and translate the visualisation. Single colours, colour collections or an entire colour library can be shared or received by internal and external users for measurement and evaluation. The app has integrated messaging allowing real-time calculations, sample results, photos, and text to be shared without needing to leave the app, to easily discuss colour issues and work on solutions, Uress said. Users can also send data from a Nix Spectro L scan to other DeltaEZ users for instant collaboration. Konica Minolta Sensing Americas, a wholly owned subsidiary of Konica Minolta Sensing Business Unit responsible for industrial colour and light measurement products, announced advances in its line of spectrophotometers used in plastics colour and appearance measurement. Fritz Baltutat, Senior Manager, said the company launched the new CM-17d vertical portable unit as the successor to its popular CM-700d unit widely

used by material suppliers in plastic, automotive, construction and other industries. The company also launched a simpler version, the CM-16d, as a replacement for the CM-600d model. The CM-17d is designed to provide higher accu-
racy measurement in a shorter measurement time. The unit has adopted a di:8° and de:8° integrating sphere that is compatible with the previous CM-700d but achieves improved measurement accuracy of black colour. Automatic opening and closing of the optical trap at the underside of the unit where measurement of the sample takes place allows the unit to achieve the aforementioned di and de values. In a test of five consecutive meas- urements of a SCI or SCE (colour) the CM-17d required approximately 9.5 s compared to 13 s for the CM-700d, Baltutat said. The portable CM-d unit offers what the company calls unprecedented accuracy/inter-instrument agreement (IIA) of a level usually only found on laboratory grade instrumentation or benchtop models. IIA makes it easier to agree on colour targets and tolerances when communicat- ing with customers or suppliers by providing values that are the same as any other device of the same model. The new CM-17d spectropho- tometer is ergonomically designed to be easy to grip for use in a wide range of measurement scenarios, including one-handed work, vertical orientation and measure- ment of small objects and curved surfaces. A built-in electronic viewfinder is installed with a slight tilt to improve visibility of the
operation screen (The CM-16d is a simpler design without a viewfinder). The
rechargeable unit offers workspace comfort through wireless connectivity. Other features include a new stand-type
charging cradle integrated with a zero-calibration box that offers storage and charging of the device when not in use. A leveling gig is useful when the main unit is turned upside down for measurement, while a tripod hole on the body can also be used to hold the instrument in place. Konica Minolta’s CM-CT1 configuration tool gives users the means to set up the unit easily and quickly. When multiple spectrophotometers are used or when the same conditions need to be set amongst multiple factories or suppliers, the settings can be compiled into a file and shared.
