Abstract: A viewer having a collapsed condition and a viewing condition. The viewer includes a front and rear wall formed of a flexible material and joined together at their top and bottom edges. The front wall includes a pair of images disposed on the interior surface of the front wall, while the exterior surface includes a reflection print. The rear wall includes a pair of viewing apertures having lenses in optical registration with the pair of images. A middle wall is disposed intermediate the front and rear walls and is joined together with the rear wall at their bottom edges. The middle wall includes at least one aperture in optical registration with the pair of images. The front and rear walls move between the viewing condition wherein the front and rear walls flex to define convex curves and the pair of images are viewable through the pair of viewing apertures, and the collapsed condition wherein the interior surfaces of the front and rear walls abut the middle wall.

Abstract: A prepress color proof can be prepared using suitable donor elements and an intermediate receiver element that has a roughened outer image receiving layer so that the color image is transferred with high image resolution. The intermediate receiver element can also have a cushioning layer beneath the outer image receiving layer that reduces the tendency for entrapped dirt particles to form minus density spot defects. In addition, a unique carrier plate can be used to carry the donor and intermediate receiver elements through laminating equipment. This carrier plate has a thermoplastic adhesive layer with sufficient tackiness to prevent irreversible dimensional change during lamination.
