Abstract
Abstract A process for the reproduction of oil painting and the like, having a relief surface, using a relief mold taken from the original and a thermoplastic foil, imprinted with a color picture corresponding to the original, the foil being molded while being heated and which includes placing the foil upon the relief mold in a fitting alignment and heating the foil essentially homogeneously to its liquefying temperature across its entire surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
151 words
A process for the reproduction of oil paintings and the like, having a relief surface, using a relief mold taken from the original and a thermoplastic foil, imprinted with the color picture corresponding to the original, said foil being molded while being heated; wherein said foil is placed with its imprinted side down on said relief mold in a fitting alignment, wherein a textile layer with a flowable component is placed over said foil, and wherein a supporting element of a heating device is placed over this layer arrangement, with the foil and the flowable component of said textile layer being then heated essentially homogeneously to liquefying temperature by means of said heating device, whereby the foil and the flowable component flow into the relief surface of said relief mold and are molded by their own weight and without the creation of a relative vacuum on one side of said foil.
Claim 2
Dependent Claim
151 words
A process for the reproduction of oil paintings and the like, having a relief surface, using a relief mold taken from the original and a thermoplastic foil, imprinted with the color picture corresponding to the original, said foil being molded while being heated; wherein said foil is placed with its imprinted side down on said relief mold in a fitting alignment, wherein a textile layer with a flowable component is placed over said foil, and wherein a supporting element of a heating device is placed over this layer arrangement, with the foil and the flowable component of said textile layer being then heated essentially homogeneously to liquefying temperature by means of said heating device, whereby the foil and the flowable component flow into the relief surface of said relief mold and are molded by their own weight and without the creation of a relative vacuum on one side of said foil.
Claim 3
Dependent Claim
19 words
The process as claimed in claim 1, wherein the textile comprises linen which has been saturated with polyvinyl chloride.
Claim 4
Dependent Claim
35 words
The process as claimed in claim 1 or 2, which further comprises pressing the support layer against the foil by its own weight and/or the additional pressure by means of a couching or pressure device.
Claim 5
Dependent Claim
37 words
The process as claimed in claims 1 or 2, which further comprises heating the foil, or the foil together with the support layer respectively beginning in the center of the relief mold and progressing towards the edges.
Claim 6
Dependent Claim
31 words
The process as claimed in claims 1 or 2, which further comprises dielectrically heating the foil, or the foil with the support layer, respectively, by means of an electric high-frequency field.
Claim 7
Dependent Claim
26 words
The process as claimed in claim 1, which further comprises heating the foil, or the foil with the support layer, respectively, by radiation with infra-red rays.
Claim 8
Dependent Claim
32 words
The process as claimed in claim 1, which further comprises heating the foil, or the foil with the support layer, respectively, by contact with a pre-heated elastic couching of high thermal capacity.
Claim 9
Dependent Claim
23 words
The process as claimed in claim 1, which further comprises galvanically metallizing the relief mold at least at its surface facing the foil.
Claim 10
Dependent Claim
21 words
The process as claimed in claim 1, wherein the relief mold is microscopically porous or provided with holes having microscopic dimensions.
Claim 11
Dependent Claim
14 words
The process as claimed in claim 1, which further comprises cooling the relief mold.
