发明名称 Clustered halftone dot design process
摘要 An idealized clustered screen is characterized spot clustering which is optimized so that clusters are about the same size and shape as they grow and are approximately equally distanced though an image. Pixels are swapped within the screen to vary its appearance. An optimization process iteratively checks a quality metric based on the optimum conditions, as pixels are swapped until an optimum screen appearance is obtained.
