Production of colored designs
First Claim
1. In the art of producing visually-pleasing design patterns of differently colored components which occupy mutually-exclusive areas and which may include either or both of black and white as respective "color components," the method of producing a replica of an original pattern of components occupying mutually-exclusive areas, which replica is suitable for use in an imaging system for producing an image of said original pattern and for arbitrarily coloring each component over a selectible range of continuously variable intensity independent of the others in said image, which method comprises providing a master of said original pattern in which each component is photometrically separable substantially in its entirety from each of the other components, photometrically separating each component from the others to form a record of said component, modulating said record uniformly throughout its confines substantially exclusively with a spatial-frequency carrier having a unique azimuthal orientation and a spatial frequency capable of resolving the individual components, and combining all of the so-modulated records to form a single replica of the original pattern in which single replica each component is located in its original relation to the other components and bears its spatial carrier to the exclusion of the spatial carriers of all the other components, for visual examination of the collective effect of the components of said image of said original pattern when produced with the aid of said replica.

Abstract
Method and apparatus are described for producing a replica of a pattern composed of differently-colored zones, mutually exclusive areas of the replica being so encoded from zone to zone that when it is suitably illuminated, the light from each zone can be treated separately from the light from each of the other zones. Apparatus is also described for reconstructing from such separately treated light an image of the original pattern in which each zone may be given an arbitrary hue and intensity. The "color" of any one zone in such image can be black or white, as well as gray.

- 5. In the art of reproducing visually pleasing design patterns of differently-colored components occupying mutually-exclusive areas of an original pattern, and which may include either or both of black and white as respective "color components", the method of arbitrarily coloring each component of a reproduced pattern over a selectible range of continuously variable intensity independent of and in unison with all the others for comparative examination of such design patterns as a whole, which comprises providing a master of said original pattern in which each component is photometrically separable from all the others, photometrically separating each component from the others to form a record of said component, modulating said record uniformly throughout its confines substantially exclusively with a spatial-frequency carrier having a unique azimuthal orientation and a spatial frequency capable of resolving the individual components, combining all of the so-modulated records to form a single replica of the original pattern in which single replica each component is located in its original relation to the other components and bears its spatial carrier to the exclusion of the spatial carriers of all the other components, illuminating said replica with light and modulating said light with said respective spatial carriers so as to diffract in a separate direction light that is representative of each of said respective components for separating light that is representative of each component substantially entirely from light that is representative of any of the others of said components, arbitrarily coloring the light that is representative of each of said components over a selectible range of continuously-variable intensity, forming from the light of all said components in unison an image of said replica, for visual evaluation of the collective effect of the components of said pattern and, making a selection on an artistic basis of images of said replica which bear visually pleasing combinations of colored components.
