ABSTRACT:
A method and arrangement for reproducing an original image has a scanner which scans and digitizes the original image into pixels, a controller coupled to the scanner to receive the digitized original image, and a printer coupled to the controller. The controller produces a first signal corresponding to a gray level halftoned representation of the digitized original image, and stabilizes the dots at specified pixels. The printer receives the first signal and reproduces the original image with stable dots at locations corresponding to the specified pixels.
