An ultra-high definition multi-spectral scanner (able to scan from the ultraviolet to infra-red spectra) with a homogeneous lighting system is being developed for the direct fast capture of images of paintings. The multi-spectral images are calibrated using the CRISATEL pigment colour charts designed specifically for painting materials. Spectrometric analysis of the varnish layers allows the effect of aged or glossy varnish to be corrected on the digital image. Simulation of varnish removal and comparison between the simulated image and measurements made on the restored paintings will assist the curator by allowing the effect of the restoration to be previewed before making a decision. Accurate colour images and life-size X-radiographs can be printed on to help the restorer and to serve as surrogates for fragile works of art. -- SCMRE
