Problems solved by technology

Nothing in the Rjumshina et al patent, however, describes subsequent masks and the alignment of any subsequent masks for controlled multicolored line art images.
Unfortunately, while Adobe Photoshop satisfactory aligns layers on the pixel level, it is difficult, if not impossible to transfer this precision to multiple film positives for controlled multicolored line art images and color separation techniques to produce photographic or blended tone gradients and images.

Embodiment Construction

[0011] The present invention is a photographic printing system and method for application of multiple masks in coloring refractory metals. The present invention applies multiple masks to color refractory metals through anodization with precise registration, including process color.

[0012] In offset, four color printing, color separations are made to give the illusion of continuous tone, photographic images using only four colors of ink. Other printing systems including Hexachrome using six colors or four colors plus one or more spot colors can also be used. This same photographic image can be achieved through an entirely different method of the present invention of color separation and assigned to dry or wet film masks to anodize refractory metals. The method of the present application is accurate to at least 85 dpi, similar to the resolution of color newspaper printing.

[0013] In the practice, a mask resists the anodization process and can be removed to add additional masks to crea...

Abstract

A photographic printing system for anodizing coloring refractory metals using computer graphic imaging is provided. The system comprises a plurality of film masks and a metal plate. Registration marks are formed in each of the film masks and the metal plate for aligning the film masks and the metal plate for controlling the color application in multicolored line art images. A method for anodizing coloring refractory metals using computer graphic imaging is also provided.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates generally to a photographic printing system and method for application of multiple masks in coloring refractory metals and, more particularly, the invention relates to the precise registration of subsequent masks for controlled multicolored line art images and using color separation techniques to produce photographic or blended tone gradients and images. [0003] 2. Description of the Prior Art [0004] A process is known for creating a mask using the dry film process as a resist in coloring refractory metals. For instance, the Rjumshina et al patent, U.S. Pat. No. 3,775,263, describes a polychromatic image formed on the surface of an article by depositing on a solid dielectric layer a thin film of a unilaterally-conductive metal or alloy thereof followed by dividing the film into separate areas in conformity with the shape of the picture to be reproduced. Nothing in the Rjumshina et al patent, ho...
