An apparatus and process for hiding the secondary image within the primary image and generating a high quality hard copy of the unified elemental image of a variety of media. The process comprises the steps of rasterizing the first image into an first elemental image and rasterizing the second image, compensated with its own inverse, into an second elemental image. The first elemental image and the second elemental image are merged into a unified elemental image based on a predetermined decoding and compensating principle, resulting in the second elemental image being hidden within the first elemental image. An output image is created based on the unified elemental image where the primary image is visible to an un-aided eye while the secondary image is hidden from the un-aided eye.

[ What is claimed:] [1.] A method as implemented on a computer system for digitally producing encoded screens for incorporating secondary information composed of pixels as an anti-counterfeiting security feature into a visible primary image for use on a document, the method comprising the steps of:(a) providing a user selected basic screen;(b) creating an encoded screen from the user selected basic screen and the secondary information by:(1) using the pixels as digital information carriers,(2) modifying a parameter of the digital information carriers, and(3) placing the modified parameter of the digital information carriers within a plurality of color layers of the primary image based on the secondary information,(c) generating a compensated screen containing the secondary information hidden within by compensating the encoded screen for any distortions;(d) screening the primary image with the compensated screen to produce a combined output image in accordance with a reproduction technology corresponding to the user selected encoding principle; and(e) reproducing the document using the reproduction technology, the document incorporating the combined output image.
