Abstract: Methods and systems for securely rendering a security feature with image data to be printed, can involve providing within the image data, data relating to a group of spots, and within the image data, mixing spots of two or more spot sizes among the group of spots to embed information within a stochastic or frequency modulation halftone image. In an embodiment, operations may be implemented for rendering a part of the image with a first spot among the group of spots and a remaining portion of the image with a second spot among the group of spots, wherein the second spot is smaller in size than the first spot.

Abstract: A photographic paper support is prepared formed by the following method: forming a paper sheet and drying it to about 10 percent water; applying an aqueous solution of hydrophobically substituted amylose starch to both sides of the sheet; drying this sheet to below 5 percent water; applying an aqueous solution of the hydrophobically substituted amylose starch to both sides of the sheet; drying this sheet to below about 10 percent water; and extruding a layer of polylefin on both sides of the paper sheet.A silver halide color photographic reflection print element is formed by coating at least one color-forming silver halide emulsion layer on a photographic paper support prepared by the above described method.
