Multi-color Properties of Silver Glaze Images Photo-engraved on Glass Plates

Recent progresses in nanotechnologies enabled the coloration of glass plates coated with silver and titanium dioxide by laser irradiation. The colored samples display very different colors according to whether they are obtained by reflection or transmission of light; in specular or diffuse directions; and with or without polarizing filters. This printing technology, that we call PICSLUP, enables the production of gonio-apparent color images. In this paper, we recall the physical principles that allow the appearance of these multi-coloration effects, show the color variations under various illumination and observation configurations, and present the first color images that we could print. We also analyze the possibility of extending the color gamut with halftoning and show some preliminary spectral reflectance and transmittance predictions done with the Yule-Nielsen modified Spectral Neugebauer model.
