Création d'objets mats : optimisation d’un procédé d’impression en relief en termes d’apparence

Abstract : 2.5D printing is between traditional color printing, for the process and its visual quality, and 3D printing, which makes forms and reliefs by ink superposition. Because of its properties, 2.5D printing could allow the realistic reproduction of objects and surfaces, but inks are too glossy. To reduce and control this glossy aspect of inks, we modulate the roughness of the printed layers, at the micro-scale, both in frequency and amplitude. Influence of parameters was measured, and different strategies were suggested to reduce sparkle and to allow the creation of matte colored layers: by constituting a 5D space where gloss and color are modeled, we can make gloss level of colored surfaces uniform.Several case studies form the Conservation of Cultural Heritage were considered, where 2.5D printing could help the curator, the conservator or the archivist. We studied in particular the issues of the the gap filling on an archaeological object, the realistic reproduction of surfaces, and the creation of matte objects for readability.
