Adobe Postscript's setoverprint and setoverprintmode operations, an imager and Object Optimized Rendering (OCR) technology can be combined to achieve a watermark result by either tagging lower image areas as text or other intents, or by changing color values. Separations from stacked objects are combinable with control over OOR tags and color values to achieve special effects are described. Mechanisms of the present embodiment would provide the option where special areas can either disappear and retain the lower object attributes or modify lower object runs with special effect algorithms.
