Artistic halftoning: between technology and art

摘要

Abstract: In the present paper, we shall focus our attention on different artistic halftoning techniques developed by the author at EPFL. First, we shall explore Artistic Screening, a library-based approach, which has been presented at SIGGRAPH95. Contour-based generation of halftone screens effectively provides a new layer of information. We show how this layer of information can be used to convey artistic and cultural elements related to the content of the reproduced images. Artistic Screening is basically black-and-white technique. Multicolor and Artistic Dithering, presented at SIGGRAPH99, extends it to multiple colors. This technique permits to print with non-standard colors such as opaque or semi-opaque inks, using traditional or artistic screens of arbitrary complexity.!42
