US4968064A — Variable color print

Claim 1

Independent Claim 164 words

A variable color print of an image, comprising: a reflective image medium including a plurality of differently oriented local image regions; each said region including a first plurality of repeated changes in reflective angle of said medium which extend substantially in a first direction in that region and are generally parallel to each other in a second direction transverse to said first direction, said repeated changes spaced to reflect rather than diffract light; and each said region further including colored material on said medium establishing a second, greater plurality of repeated variations in color generally aligned with said repeated reflective changes in that region and which extend in said first direction and are generally parallel to each other in said second direction, said repeated reflective changes selectively preventing viewing of one or more of said color variations and selectively highlighting one or more other color variations at different viewing angles to generate changes in color of the viewed image as the viewing angle changes.

Claim 2

Dependent Claim 164 words

A variable color print of an image, comprising: a reflective image medium including a plurality of differently oriented local image regions; each said region including a first plurality of repeated changes in reflective angle of said medium which extend substantially in a first direction in that region and are generally parallel to each other in a second direction transverse to said first direction, said repeated changes spaced to reflect rather than diffract light; and each said region further including colored material on said medium establishing a second, greater plurality of repeated variations in color generally aligned with said repeated reflective changes in that region and which extend in said first direction and are generally parallel to each other in said second direction, said repeated reflective changes selectively preventing viewing of one or more of said color variations and selectively highlighting one or more other color variations at different viewing angles to generate changes in color of the viewed image as the viewing angle changes.

Claim 3

Dependent Claim 43 words

The variable color print of claim 1 in which said image medium includes a substrate and reflective material disposed on said substrate.

Claim 5

Dependent Claim 22 words

The variable color print of claim 1 in which said repeated changes include undulations in a reflective surface of said image medium.

Claim 6

Dependent Claim 14 words

The variable color print of claim 4 in which said undulations are generally sinusoidal.

Claim 7

Dependent Claim 27 words

The variable color print of claim 5 in which said undulations are substantially identical to establish a regular series of spaced crests on said reflective image medium.

Claim 8

Dependent Claim 21 words

The variable color print of claim 4 in which said undulations include a plurality of grooves established in said reflective surface.

Claim 9

Dependent Claim 15 words

The variable color print of claim 4 in which said undulations are substantially regularly spaced.

Claim 10

Dependent Claim 22 words

The variable color print of claim I in which said repeated color variations are spaced from said repeated changes in reflective angle.

Claim 11

Dependent Claim 23 words

The variable color print of claim 1 in which said color variations are regular in at least two of said local image regions.

Claim 12

Dependent Claim 32 words

The variations color print of claim 2 in which said repeated reflective changes prevent viewing of said two different colors at a different viewing angle and enable viewing of two other colors.

Claim 13

Dependent Claim 22 words

The variable color print of claim 1 in which said local image region includes at least sixty-five repeated reflective changes per inch.

Claim 14

Dependent Claim 22 words

The variable color print of claim 12 in which said local image region includes 100 to 400 repeated reflective changes per inch.

Claim 15

Dependent Claim 20 words

The variable color print of claim 1 in which said different local image regions represent different intensities of the image.

Claim 16

Dependent Claim 25 words

The variable color print of claim 1 in which at least two repeated variations in color are associated with each repeated change in reflective angle.

Claim 17

Dependent Claim 23 words

A variable color print of claim 4 in which said repeated variations in color are disposed on said undulations of the reflective surface.

Claim 18

Dependent Claim 145 words

A variable color print of an image, comprising: a translucent image medium including a plurality of differently oriented image regions; each said region including a first plurality of repeated changes in transmissivity of said medium which extend substantially in a first direction within that region and are generally parallel to each other in a second direction transverse to said first direction; and each said region further including colored material on said medium establishing a second, greater plurality of repeated variations in color distinct from said repeated changes in transmissivity and generally aligned with said transmissivity changes which extend in said first direction and are generally parallel to each other in said second direction, said transmissivity changes selectively preventing viewing of one or more of said color variations at different viewing angles to generate changes in color of the viewed image as the viewing angle changes.

Claim 19

Dependent Claim 145 words

A variable color print of an image, comprising: a translucent image medium including a plurality of differently oriented image regions; each said region including a first plurality of repeated changes in transmissivity of said medium which extend substantially in a first direction within that region and are generally parallel to each other in a second direction transverse to said first direction; and each said region further including colored material on said medium establishing a second, greater plurality of repeated variations in color distinct from said repeated changes in transmissivity and generally aligned with said transmissivity changes which extend in said first direction and are generally parallel to each other in said second direction, said transmissivity changes selectively preventing viewing of one or more of said color variations at different viewing angles to generate changes in color of the viewed image as the viewing angle changes.

Claim 20

Dependent Claim 43 words

The variable color print of claim 17 in which said local image regions are oriented in relation to each other such that for each viewing angle at least two different colors, each in a different local image region, are visible for said image.

Claim 21

Dependent Claim 18 words

The variable color print of claim 17 in which said transmissivity changes include a plurality of opaque lines.

Claim 22

Dependent Claim 29 words

The variable color print of claim 18 in which said color variations are spaced from said opaque lines in a third direction normal to said first and second directions.

Claim 23

Dependent Claim 36 words

The variable color print of claim 20 in which said opaque lines are disposed on a first surface of said image medium and said colored material is disposed on a second surface of said image medium.

Claim 24

Dependent Claim 14 words

The variable color print of claim 17 in which said image medium is transparent.

Claim 25

Dependent Claim 28 words

The variable color print of claim 17 in which said transmissivity changes include undulations in said medium to variably alter the path of light passing through said medium.

Claim 26

Dependent Claim 31 words

The variable print of claim 23 in which said undulations are at least partly covered with a reflective medium for reflecting light at different angles to generate the viewed color changes.
