ABSTRACT:
An image processing method for adding noise-like texture to the print through the manipulation of halftone screens. The method injects noise into halftone thresholds arrays rather than directly into the image. The method operates by creating a halftone threshold array of suitable size to support the desired noise characteristics. A textured pattern of a corresponding size is created having the desired noise characteristics and boundary transitions. The texture pattern is applied to the halftone threshold array by an amount determined by a noise amplitude control curve. The incoming contone image is then processed with the modified halftone screen.
