Prevest Research institute is equipped with a TECHKON SpectroDens – Spectro-Densitometer which is an all-purpose measurement device that is universally used for quality control in the printing industry as well as for other tasks, where colors have to be judged critically. The instrument is used for standard colorimetric functions. Measurement is spectral, i.e. the entire color information – the spectral fingerprint of the color – is precisely registered. The data is

converted into measurement data for descriptive analysis and display. The entire CIE L*a*b* color circle appears in the high resolution color display. In the color library 25.000 reference colors and complete digital color books can be saved. SpectroDens is ISO-compliant for standardized measurement.

The instrument is very much useful for color comparison such as shades and also for digital analysis. Spectral range of instrument is from 400 to 700 nm in 10 nm steps, spectral resolution 10 nm, pixel distance sensor < 3 nm. The measurement uses the software TECHKON SpectroConnect, for fast and easy exchange of digital color libraries, as well as measured references and samples.
