We released Pigments Checker v.2.1. We constantly add features to improve this tool: It comes with our new Multispectral Imaging calibration card. Commercial gray cards for photography cannot be used for multispectral imaging since they absorb near UV and violet radiation. We developed a gray card to cover the 400-1000 nm spectral range. It has 6 swatches,
CHSOS is calling for Laboratories and Research Groups interested to collaborate and contribute to the Free and Downloadable spectral database of pigments in Pigments Checker. We already provided Reflectance spectra which can be accessed and downloaded from the interactive table. Reflectance spectroscopy DOWNLOAD Database: A.
