Abstract: A variable color print of an image includes a reflective image medium including a plurality of different, locally colored, image regions; a first plurality of repeated changes in reflective angle of the image medium which extend in a first direction and are parallel to each other in a second direction transverse to the first direction; each locally colored image region including at least one local color medium disposed on the reflective medium; each local color medium includes at least one color sequence, each sequence extending in the second direction and including at least two different color variations; and each color variation is aligned with the repeated changes in reflective angle such that the repeated changes in reflective angle selectively prevent viewing of at least one of the color variations and selectively highlight at least one of the color variations at different viewing angles to generate changes in color of the locally colored image regions as the viewing angle changes.

Abstract: A computerized technique for generating masters for embossing and printing color images with local regions of variation of an optical characteristic such as reflectance is disclosed. The color image is read into a computer and displayed on the computer screen. An electronic embossing mask is created for each local region which is to have a preselected optical variation. The line pattern is designated for each local region mask and an embossing film is exposed with each electronic embossing mask for creating in the embossing film a composite image including each line pattern in each local region. A plurality of electronic color separation masks are generated from the original color image, and each of these is combined with an electronic embossing mask to form an electronic line color separation mask having line patterns which correspond to those designated for the local regions.

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.

Abstract: An easel display stand including: an easel support section having a trapezoidal hole; and an erectable easel section for face-to-face mounting with the support section having a base line; a spine; means for hingeably interconnecting the spine at the base line; a pair of side walls; means for hingeably interconnecting each of the side walls with a longitudinal edge of the spine; a pair of retainer portions; means for hingeably interconnecting each of the retainer portions with one of the side walls; the base line being generally aligned with the top of the trapezoidal hole and the means for hingeably interconnecting the retainer portions and the side walls being generally aligned with the angled sides of the trapezoidal hole when the easel section is erected through the trapezoidal hole.
