摘要：
A processor controls a marking engine to print a uniform region having a visually uniform color for an observer within all areas of the uniform region. The processor also controls the marking engine to print different gloss patterns within the uniform region. The different gloss patterns have first and second gloss regions, and the gloss difference between the first and second gloss regions forms gloss marks. Additionally, the processor controls the marking engine to print different infrared patterns within the uniform region to form infrared marks. In some embodiments, the infrared patterns are only within the first gloss regions and are not within the second gloss regions.
