摘要:
Printing a screened image includes a computer for converting a contone image to a digital image. A digital front end provides a screening tile, a dither magnitude curve, a spot function for each of the cells in the screening tile and a displacement vector for each of the cells. The digital front end displaces the center of each cell spot function and constructs a halftone image from the contone image and the screening tile by comparing value of each pixel from the contone image to a corresponding threshold value from the screening tile. If the pixel value exceeds the threshold value set a corresponding pixel in the halftone image to one otherwise set the corresponding pixel in the halftone image to zero. An imaging system prints the halftone image on a substrate.
