发明名称 METHOD AND APPARATUS FOR GENERATING DIGITAL, ANGLED HALFTONE SCREENS
摘要 <p>In digital halftone color printing, low spatial frequency patterning can occur due to the interaction of the overlapping angled halftone screens. The moire patterning can be minimized by automatically constructing digital halftone angled screens (110) from screen tiles (8) which are designed to minimize the low spatial frequency patterning.</p>
