Abstract
Abstract The invention concerns a process for the reproduction of oil paintings or similarly surface-textured images by use of a relief form transferred from an original and a smooth thermoplastic color photo film that is imprinted corresponding to the original, with the film, together with a reenforcing back ply, being laid onto the relief form in fitting alignment and with the film and reenforcing ply being deformed by heating to correspond to the surface texture of the original.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
205 words
In a process for the reproduction of oil paintings or similarly surface-textured images by initially forming a relief form on the original, removing the relief form from the original, and forming a reenforced smooth thermoplastic color film imprinted in a manner corresponding to the original; wherein the reenforced film and relief form are aligned, and the film being thereafter deformed by heat until the surface texture of the film corresponds to the original through the use of the relief form, said process being characterized in that: (a) said reenforced colored film consists of a material capable of being heated dielectrically at high frequency radiation and a reenforcement ply; (b) said reenforcement ply consists of a woven webbing having a coating thereon, said coating being capable of being dielectrically heated by high frequency radiation and capable of being welded to the surface of said color film; (c) said process being further characterized in that said reenforcing ply is placed on the back surface of said color film and subjected to high frequency radiation until heated dielectrically, and wherein the back surface of the reenforcing ply is exposed to a pressure equalizing plate fabricated from closed-cell foam synthetic resinous material which is substantially immune to dielectric heating.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
The process as set forth in claim 1 being particularly characterized in that the surface of the relief form in contact with the color film is metallic.
Claim 4
Dependent Claim
51 words
The process as set forth in claims 1 or 2 being particularly characterized in that said pressure equalizing plate and relief form are disposed between a pair of opposed electrodes, and wherein each of said electrodes comprises plural segments, and wherein means are provided for periodically energizing each of said segments.
Claim 5
Dependent Claim
20 words
The process as set forth in claim 1 being particularly characterized in that said colored film consists of polyvinyl chloride.
Claim 6
Dependent Claim
20 words
The process as defined in claim 1 being particularly characterized in that said pressure equalizing plate consists of silicone rubber.
Claim 7
Dependent Claim
19 words
The process as set forth in claim 1 being particularly characterized in that said woven webbing is linen cloth.
