摘要:
A method for defining a gloss effect in a printed document includes printing a document region with first and second colorant combinations. The first colorant combination defines a first colorant stack height and said second colorant combination defines a second colorant stack height that differs from the first colorant stack height. As such, the document region has a first appearance when viewed straight-on and a second appearance when viewed at an angle. In one example, the first colorant combination is black (K) colorant that results in a one-level stack height and the second colorant combination is cyan, magenta, and yellow (CMY) colorants that result in a three-level stack height. In another example, the second colorant combination can be cyan, magenta, yellow and black (CMYK) colorants that define a four-level stack height. In such case, both colorant combinations appear as black in straight-on viewing or scanning, while the average color and/or luminance of the colorant combinations will differ from each other when the document region is viewed at an oblique angle. The desired gloss font or other gloss effect is defined by selective placement of the first and second colorant combinations relative to each other. Font sizes of 3 points or less can be defined.
