Abstract
The present invention relates to the segmentation of an image into a main area and a image segment for variable glossmark data. By selectively applying halftones with anisotropic structure characteristics which are significantly different in orientation while remaining identical in density to the image segment, a variable glossmark may be superimposed within an image with reduced processing and storage requirements.
Claims36
A method for variable glossmark control comprising:
- segmenting an image of interest into a main area and a segment area.
- selecting a first halftone having a first anisotropic structure orientation;
- selecting a second halftone having a second anisotropic structure orientation different from that of the first halftone;
- applying the first halftone to the main area and at least some portion of the segment area;
- and
- applying the second halftone to the remaining portion of the segment area to produce a variable glossmark.
