Adjusting halftone patterns to maintain print quality |
摘要 |
<p>A method and apparatus to maintain constant tone reproduction on a printed output over time. This is accomplished by performing template matching on a halftoned binary image prior to sending the binary image to a Raster Image Processor (ROS). The template matching operation selectively replaces bit patterns in the binary image with template bit patterns, based on a detected xerographic density. <IMAGE></p> |
