Abstract
The present invention is directed to a system and method for halftone screening. A system for halftone screening includes a memory including a look-up table, the look-up table including screen frequency data representative of the selected screen frequencies for an associated visual output rendering device and tonal level data corresponding to the screen frequency data. The system further includes means adapted for receiving image data representative of a continuous tone image, segmenting means adapted for segmenting received image data into apportioned image data representative of a plurality of image portions, each image portion including a tonal value associated therewith, and means adapted for communicating data representative of each tonal value to the look-up table, whereby corresponding tonal level data is output therefrom.
