Abstract: | For numerous digital imaging applications, there is a need to maintain the highest quality perceived image, while utilizing a printer or display that can only achieve a limited number of output states. Digital halftoning is the approach that has been widely used to meet this demand. In this focus paper, we provide a short summary of halftone techniques, then we concentrate on the newer and expanding roles of stochastic halftone screens—which are free of regular periodic structures and have numerous advantages in quality color rendering. We address some theoretical issues, design and optimality issues, printer compensation issues, and color quality issues that pertain to the development and use of stochastic screens for electronic imaging devices. |
