The appearance of effect finishes is influenced by different viewing angles and viewing conditions. Apart from a light-dark flop and color shift special sparkling effects can be created.
The QTK-mac spectrophotometer is unique as it measures both multi-angle color and flake characterization in one portable device.
The shape of the instrument is designed to ensure easy handling and true portability. Due to its intuitive menu quality control of metallic finishes has never been easier.
In order to guarantee stable positioning, the QTK-mac i is equipped with trigger pins on the bottom plate of the instrument. If the pins do not have contact with the surface, an error message will be displayed. This ensures reproducible results on test panels as well as curved parts (r > 500 mm). Additionally, the surface temperature is measured and saved with each measurement.
The QTK-mac i spectrophotometer uses a light source with long-term stability and patented illumination control which provides superior accuracy and low maintenance for many years.
The instrument is operated with a rechargeable battery pack (Li-Ion). The docking station automatically charges the battery pack in the instrument as well as a spare pack located in the docking station. Optionally the instrument can be operated with 4 standard mignon alkaline or rechargeable batteries. The docking station also transfers measured data to a PC.

Measurement of effect finishes on small or curved parts
Special effect finishes are used in many applications to create new color impressions pronouncing the design of a product. Objects like mobile phone housings, bicycles or window handles are very small or curved. They require a color instrument with small aperture and repeatable sample placement. QTK-mac i with 12 mm aperture guarantees repeatable results even on such products.
