N2 - Being able to link captured material characteristics and fabricable material appearance attributes is important for creatinglife-like reproductions. In this paper we propose a method for gloss calibration, and an approach for gloss gamut mapping, aspart of an integrated approach for color, topography and gloss reproduction. For gloss calibration, gloss calibration targetswere printed in the primary printing colors (CMYK and White), with uniform gloss in equal distant gloss levels. These targetswere scanned using the proposed gloss scanner. To create the gloss gamut map, a monotonic curve was fitted to the mean glossscan values at different gloss levels. Analysis of fitted curves indicated that the gloss mapping is independent of the diffusecolors. As a case study, the painting ‘Fruit Still Life’ by Cornelis de Heem was scanned, and the measured gloss was mappedto printable gloss levels using the relation described by the fitted curve. The printed result shows good correspondence to thepainting’s appearance, with clearly distinguishable gloss features for the in-gamut glass values.
