Abstract
A graphic communication medium is disclosed in which a dry pastel substance is placed in solution and uniformly applied over a substrate such as paper. The substrate may include a drawing beneath the pastel such that areas of the drawing may be highlighted by selectively removing the dried pastel from the area to be highlighted. The highlighted area is then re-covered by rubbing pastel from adjacent areas of the substrate thereover.
Claims19
A graphic communication device comprising a sheet of paper having a front and back surface with a uniformly applied layer of dry pastel substance, said pastel substance being suspended in solution for application to said paper, said pastel substance being infused onto said front surface and being selectively removable therefrom, said pastel being translucent and of a uniform color different from that of said paper such that, when removed, a contrast is presented between said paper and said pastel layer, said pastel also being applied in a thickness sufficient to permit re-covering of said front surface by spreading said dry pastel over the area from which it was removed.
A method of graphic communication comprising the steps of:
- a) suspending a pastel substance in solution;
- b) applying a uniform layer of said solution to one surface of a sheet of paper;
- c) selectively removing areas of said pastel for creating a contrast between the paper and pastel and highlighting areas of said paper;
- d) rubbing the pastel remaining on the paper over the area of the paper from which it was removed with a cloth or the like for re-covering the paper with the pastel remaining on the paper and eliminating the previously created highlighted area;
- and
- e) repeating steps c) and d) for selectively highlighting areas of said paper.
A method of preparing a graphic communication medium having as a characteristic a substrate with a coating of a dry pastel substance, said substance having a thickness sufficient to permit selective removal of one or more selected areas of said coating and later recovering of said selected area or areas by spreading the remaining substance over the area from which it had been removed comprising the steps of:
- a) suspending in solution a pastel substance;
- b) applying said pastel substance in solution to the surface of a substrate;
- c) allowing said solution to dry, leaving a dry pastel substance coating said substrate, said substance being selectively removable therefrom.
