color measurement at the lab

Spectral color measurement in laboratory with 45°: 0° geometry (CIE standard)
- with and without UV radiation to determine the optical brightener.

The ERX30 is the first spectrophotometer with 45°:0° geometry and adjustable UV component. This allows an exact measurement of the basic whiteness and the optical brightener in the paper. Even critical colors and demanding applications can be measured accurately due to the excellent spectral resolution of 1 nm.

The wide spectrum from 330 nm to 730 nm provides information not only in the visible range but also in the UV range. Due to the 45°:0° geometry the measurements correlate excellently with the visual impression. This geometry is also a standard in the printing industry and in inlinecolor measurement. Printers and paper manufacturers now speak the same "colour language".
