Abstract
Abstract A variable color print of an image including an image medium having a plurality of differently oriented local image regions. Each region includes a number of periodic variations in an optical characteristic of the medium which extend substantially in a first direction within that region and are generally parallel to each other in a second direction transverse to the first direction. Each region further includes a number of periodic variations in color which extend in the first direction and are generally parallel to each other in the second direction and are generally aligned with the periodic optical variations in that region. The periodic optical variations selectively prevent viewing of one or more of the color variations at different viewing angles to generate changes in color of the viewed image as the viewing angle changes. A method of forming such a variable color print is also disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
158 words
A method of forming a variable color print of an image, comprising: designating a number of different regions of the image; selecting a line pattern for each region, said line patterns each including a plurality of spaced, substantially parallel lines at a density of from 100 to 400 lines per inch; establishing a pattern mask of the image having the line patterns oriented differently for at least two of the respective regions; transferring the pattern mask to an image medium; forming a plurality of color images from the pattern mask, one color image for each color selected for print; selecting a plurality of colored materials to be applied to said medium; and transferring each selected colored material to the image medium to generally align the colors with the pattern to selectively prevent viewing of one or more of the colors at different viewing angles, and generate changes in color of the viewed image as the viewing angle changes.
Claim 2
Independent Claim
158 words
A method of forming a variable color print of an image, comprising: designating a number of different regions of the image; selecting a line pattern for each region, said line patterns each including a plurality of spaced, substantially parallel lines at a density of from 100 to 400 lines per inch; establishing a pattern mask of the image having the line patterns oriented differently for at least two of the respective regions; transferring the pattern mask to an image medium; forming a plurality of color images from the pattern mask, one color image for each color selected for print; selecting a plurality of colored materials to be applied to said medium; and transferring each selected colored material to the image medium to generally align the colors with the pattern to selectively prevent viewing of one or more of the colors at different viewing angles, and generate changes in color of the viewed image as the viewing angle changes.
Claim 3
Dependent Claim
24 words
The method of claim 1 in which transferring includes generating a die from the pattern mask and impressing the image medium with the die.
Claim 4
Dependent Claim
13 words
The method of claim 2 in which the impressing includes heat transfer debossing.
Claim 5
Dependent Claim
27 words
The method of claim 2 in which forming a plurality of color images includes making a printing plate for each color to represent the respective color image.
Claim 6
Dependent Claim
33 words
The method of claim 1 in which the image medium is translucent and transferring includes placing the pattern mask on the translucent image medium to selectively vary the transmissivity of the image medium.
Claim 7
Dependent Claim
31 words
The method of claim 1 in which forming a plurality of color images includes selecting different densities at which each color is to be printed for different regions of the image.
Claim 8
Dependent Claim
11 words
The variable color print formed by the method of claim 1.
Claim 9
Independent Claim
166 words
A method of forming a variable color print of an image, comprising: identifying among different region of the image at least two intensities; selecting a line pattern for each intensity, said line patterns each including a plurality of spaced, substantially parallel lines at density of from 100 to 400 lines per inch; establishing a pattern mask of the image having the line patterns oriented differently for the respective intensity regions; transferring the pattern mask to an image medium; forming a plurality of color plates from the pattern mask, one color plate for each color selected for the print; selecting a plurality of colored materials to be applied to said image medium; and printing each selected colored material on the image medium to generally align the colors with the pattern to selectively prevent viewing of one or more of the colors and highlight one or more other colors at different viewing angles, and generate changes in the color of the viewed image as the viewing angle changes.
Claim 10
Independent Claim
166 words
A method of forming a variable color print of an image, comprising: identifying among different region of the image at least two intensities; selecting a line pattern for each intensity, said line patterns each including a plurality of spaced, substantially parallel lines at density of from 100 to 400 lines per inch; establishing a pattern mask of the image having the line patterns oriented differently for the respective intensity regions; transferring the pattern mask to an image medium; forming a plurality of color plates from the pattern mask, one color plate for each color selected for the print; selecting a plurality of colored materials to be applied to said image medium; and printing each selected colored material on the image medium to generally align the colors with the pattern to selectively prevent viewing of one or more of the colors and highlight one or more other colors at different viewing angles, and generate changes in the color of the viewed image as the viewing angle changes.
