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 the y 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 pixe ls are swapped until an optimum screen appearance is obtained. -19-
