BYK-Gardner USA, a member of the BYK Additives & Instruments division of ALTANA and the manufacturer and distributor of quality control instruments for color, appearance and physical properties testing introduces a new instrument to objectively detect and quantify fluorescent light excited in the visible range: the BYK-mac i spectrophotometer.
The BYK-mac i is equipped with additional out-of-plane sensors that measure the fluorescent light in clearly defined wavelength ranges. To quantify the fluorescent light, BYK-mac i calculates a new index known as the “Intensity Emission value” which can be used as a preliminary indicator for light fastness.
Due to the highly stable LED illumination, fluorescent color measurements can now be repeatable with one BYK-mac (no warm-up time, no temperature drift) and reproducible from BYK-mac to BYK-mac (no lamp aging). This allows usage of digital standards among the complete supply chain – the key to global color QC management.
The new BYK-mac i spectrophotometer, as well as its renowned predecessor the BYK-mac, objectively measures total color impression of effect coatings:
-
Flake characterization: by measuring with a camera the visual impression of sparkling and graininess, simulating effect changes under direct and diffuse lighting conditions
-
Multi-angle color measurement: “before and behind the specular reflection” to give more information about color travel of special effect finishes
The shape of the BYK-mac i is designed to ensure easy handling and true portability. In order to guarantee stable readings on flat and curved samples, the BYK-mac i is equipped with trigger pins on the bottom plate of the instrument.
Quality control of effect finishes is made truly efficient with menu guided operation according to customer specific sampling procedures, designated buttons for standard and sample readings and a large, easy-to-read color display. For further analysis and professional documentation of measurement results, the BYK-mac i comes with the software, smart-chart, for process control and lab analysis with online mode.
