Abstract
Abstract A silicone rubber mold is made of a painting having brush or palette-knife strokes. A sheet of transparent vinyl is placed over a printed reproduction of this painting, and the mold is placed over the sheet. The latter is then bonded to the reproduction while simultaneously being flow-molded under application of heat and pressure, so that the sheet is provided with relief replicas of the brush or palette-knife strokes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A METHOD OF MAKING A PAINTING HAVING SIMULATED BRUSH STROKES OR PALETTE-KNIFE STROKES, COMPRISING THE STEPS OF PROVIDING A PAINTING HAVING BRUSH STROKES OR PALETTE-KNIFE STROKES, DIRECTLY TAKING OF SAID PAINTING A SILICONE RUBBER MOLD HAVING THE STROKES THEREON IN FORM OF CORRESPONDING RECESSES, PLACING A SHEET OF TRANSPARENT THERMOPLASTIC SHEET MATERIAL OVER A PRINTED REPRODUCTION OF SAID PAINTING, AND FORMING SAID SHEET AT ELEVATED TEMPERATURE AND UNDER APPLICATION OF PRESSURE IN A SAID MOLD WITH RAISED REPLICAS OF SAID STROKES WHILE SEALING SAID SHEET TO SAID PRINTED REPRODUCTION, THEREBY PRODUCING A
Claim 2
Independent Claim
92 words
A METHOD OF MAKING A PAINTING HAVING SIMULATED BRUSH STROKES OR PALETTE-KNIFE STROKES, COMPRISING THE STEPS OF PROVIDING A PAINTING HAVING BRUSH STROKES OR PALETTE-KNIFE STROKES, DIRECTLY TAKING OF SAID PAINTING A SILICONE RUBBER MOLD HAVING THE STROKES THEREON IN FORM OF CORRESPONDING RECESSES, PLACING A SHEET OF TRANSPARENT THERMOPLASTIC SHEET MATERIAL OVER A PRINTED REPRODUCTION OF SAID PAINTING, AND FORMING SAID SHEET AT ELEVATED TEMPERATURE AND UNDER APPLICATION OF PRESSURE IN A SAID MOLD WITH RAISED REPLICAS OF SAID STROKES WHILE SEALING SAID SHEET TO SAID PRINTED REPRODUCTION, THEREBY PRODUCING A
Claim 3
Dependent Claim
42 words
A method as defined in claim 1, wherein the step of providing said painting comprises forming the strokes to be simulated on a reproduction of the original painting with a painting medium, and permitting the medium to set before taking said mold.
Claim 4
Dependent Claim
48 words
A method as defined in claim 1, wherein the step of taking said mold comprises applying silicone rubber in flowable state onto said painting, allowing the silicone rubber to set so as to obtain said mold, and thereupon removing the thus obtained silicone rubber mold from said painting.
Claim 5
Dependent Claim
15 words
A method as defined in claim 1, wherein said thermoplastic sheet material is polyvinyl chloride.
Claim 6
Dependent Claim
36 words
A method as defined in claim 1, wherein the step of forming comprises applying said mold to said sheet under pressure, and dielectrically heating said sheet so as to flow mold the material of the same.
Claim 7
Dependent Claim
40 words
A method as defined in claim 1, wherein the step of forming comprises subjecting said sheet to RF heating under simultaneous application of pressure, to thereby flow-mold the sheet to the contour of the mold-surfaCe of said silicone rubber mold.
