Abstract
An apparatus for enhancing halftone image (204) appearance for imaging on a flexographic plate (108) includes a computer (130) adapted to receive a halftone image; an analysis element adapted to scan the previously produced halftone image and to detect areas (404) in the previously produced halftone image which are populated with dots which are smaller than a previously set minimal dot size value; an enhancement element adapted to replace the small dots with a reduced number of dots wherein each of the reduced number of dots are larger in size (504) than the small dots and wherein each of the reduced number of dots maintain original geometric characteristics of the small dots to create an enhanced halftone image; and an imaging head adapted to image the enhanced halftone image on an imaging system.
