Abstract
An automatic trapping method and system is used for packaging printing. The method includes translating trapping objects into simple color blocks, scanning all of the blocks and attaining trapping boundaries, determining whether the color blocks on both sides of the trapping boundaries meet the trapping rule depending on the ink dots percentage and luminance, connecting trapping boundaries by analyzing regions, creating trapping zone and filling ink into the zone and reducing color.
