Abstract
Abstract A method of drawing an original image by the selective controllable removal of a removable coating capable of producing intermediate half-tones of a starting shade for the coating by such controllable removal. The coating has a starting shade which contrasts with the shade of the underlying layer, which may be the sheet itself, and is partially removable, such as by partial erasure such as for ink coating or controlled application of a solvent such as for an oil paint coating to produce intermediate shades of the starting shade. More than one contrasting erasable or dissolvable coating layer may be provided in which instance selective erasing or dissolving of one or more of the coating layers, either wholly or partially, may be utilized to draw the original image.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
152 words
A METHOD OF DRAWING AN ORIGINAL IMAGE COMPRISING THE STEPS OF: PROVIDING A SHEET HAVING A SURFACE AREA UPON WHICH SAID ORIGINAL IMAGE IS TO BE DRAWN, SAID SURFACE AREA HAVING A DISSOLVABLE COATING COVERING SUBSTANTIALLY ALL OF SAID SURFACE AREA, SAID SURFACE AREA HAVING A GIVEN SHADE, SAID COATING HAVING A STARTING SHADE WHICH CONTRASTS WITH THE SHADE OF SAID SURFACE AREA; AND SELECTIVELY DISSOLVING SAID COATING WITH A CORRESPONDING SOLVENT THEREFOR TO PRODUCE SAID ORIGINAL, SAID ORIGINAL, IMAGE BEING DRAWN, SUBSTANTIALLY BY SAID SELECTIVE DISSOLVING, AT LEAST A PORTION OF SAID ORIGINAL IMAGE BEING PRODUCED BY PARTIALLY DISSOLVING AT LEAST A PORTION OF SAID COATING IN A GIVEN AREA BY PROGRESSIVELY INCREASING THE SOLVENCY THEREOF IN SAID SOLVENT TO PRODUCE TRUE HALF-TONES OF SAID STARTING SHADE IN SAID GIVEN AREA, WHEREBY AN ORIGINAL IMAGE CAPABLE OF HAVING A FULL RANGE OF TRUE HALF-TONES OF SAID STARTING SHADE CAN BE PRODUCED.
Claim 2
Independent Claim
152 words
A METHOD OF DRAWING AN ORIGINAL IMAGE COMPRISING THE STEPS OF: PROVIDING A SHEET HAVING A SURFACE AREA UPON WHICH SAID ORIGINAL IMAGE IS TO BE DRAWN, SAID SURFACE AREA HAVING A DISSOLVABLE COATING COVERING SUBSTANTIALLY ALL OF SAID SURFACE AREA, SAID SURFACE AREA HAVING A GIVEN SHADE, SAID COATING HAVING A STARTING SHADE WHICH CONTRASTS WITH THE SHADE OF SAID SURFACE AREA; AND SELECTIVELY DISSOLVING SAID COATING WITH A CORRESPONDING SOLVENT THEREFOR TO PRODUCE SAID ORIGINAL, SAID ORIGINAL, IMAGE BEING DRAWN, SUBSTANTIALLY BY SAID SELECTIVE DISSOLVING, AT LEAST A PORTION OF SAID ORIGINAL IMAGE BEING PRODUCED BY PARTIALLY DISSOLVING AT LEAST A PORTION OF SAID COATING IN A GIVEN AREA BY PROGRESSIVELY INCREASING THE SOLVENCY THEREOF IN SAID SOLVENT TO PRODUCE TRUE HALF-TONES OF SAID STARTING SHADE IN SAID GIVEN AREA, WHEREBY AN ORIGINAL IMAGE CAPABLE OF HAVING A FULL RANGE OF TRUE HALF-TONES OF SAID STARTING SHADE CAN BE PRODUCED.
Claim 3
Dependent Claim
55 words
A method in accordance with claim 1 wherein said dissolving step includes the further step of progressively applying a predetermined quantity of said solvent having a predetermined solubility with respect to said coating to progressively reduce said coating by its solvency in relation to said solvent for producing said true half-tones of said starting shade.
Claim 4
Dependent Claim
37 words
A method in accordance with claim 2 wherein said applying step includes the further step of successively brushing said solvent on said coating to progressively reduce said coating for producing said true half-tones of said starting shade.
Claim 5
Dependent Claim
65 words
A method in accordance with claim 1 wherein said providing step comprises providing a sheet with said surface area having at least a first uppermost coating layer and a second coating layer underlying said first layer, at least said uppermost coating layer being a dissolvable coating, said first and second layers having contrasting starting shades, said sheet being a backing layer for said coating layers.
Claim 6
Dependent Claim
66 words
A method in accordance with claim 4 wherein said providing step comprises providing said surface area wherein said first and second coating layers are dissolvable, and said selective dissolving step comprises producing at least a portion of said original image by substantially dissolving at least a portion of said uppermost coating layer and partially dissolving at least a portion of said underlying coating layer starting shade.
Claim 7
Dependent Claim
42 words
A method in accordance with claim 1 wherein said providing step comprises providing a dissolvable oil paint coating for said surface area and said selective dissolving step comprises selectively Dissolving said oil paint coating by progressively increasing the solvency thereof in turpentine.
Claim 8
Dependent Claim
55 words
A method in accordance with claim 1 wherein said dissolving step includes the further step of progressively applying a predetermined concentration of said solvent having a predetermined solubility with respect to said coating to progressively reduce said coating by its solvency in relation to said solvent for producing said true half-tones of said starting shade.
