Effect of halftones on printing iridescent colors

The iridescence effect, produced by structural color, is difficult (if not impossible) to capture and print using traditional CMYK pigments. RGB pigments, nonetheless, generate colors light interference. layered surface structure generated pigments’ particles reflects different wavelengths of in viewing angles. In printed media, will collectively influence the optical response surface, depending on their size, orientation, structure, dimensions, ultimately, affecting visual characteristics image perceived observer. this work, we have studied halftones’ structures images, with inks via screen printing. We investigated creating spatial combinations that reproduce iridescent effect a headdress made quetzal feathers. applied first-order, second-order, structure-aware FM halftones compare how they reproduction material qualities object represented image. results show structure-ware improve representation details and, therefore, it could better convey 3D features produce original feathers headdress.
