Abstract
Abstract This invention relates to a method for illustrating wherein the illustration is made on one side of a screen, the drawing ink penetrates the screen and one can view the drawing as it is being made from the other side of the screen without the artist or his drawing implements being visible, and also to a screen for drawing in this fashion. With this invention the illustration is done on a specially selected and treated fabric so that the artist''s ink penetrates between the threads of the fabric by capillary action and does not feather or spread laterally of the fabric. The fabric is a non-absorbent one such as a polyester, and it is treated with a fixative at the thread intersections to prevent ink from running along the threads in a lateral direction.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
118 words
A method of illustrating comprising the steps of setting a transparent panel in an operative position, applying to the back surface of said panel a sheet of cloth having intersecting threads of a non-absorbent material which define ink passages from one face thereof to the other face thereof, adhering the intersections of the threads of said cloth with a fixative, passing an ink by capillary action from the surface of said cloth that is exposed to the surface of said cloth that lies against said panel at selected areas of the cloth to form an illustration on the surface of said cloth that lies against said panel, said illustration being viewable from the front surface of said panel.
Claim 2
Independent Claim
118 words
A method of illustrating comprising the steps of setting a transparent panel in an operative position, applying to the back surface of said panel a sheet of cloth having intersecting threads of a non-absorbent material which define ink passages from one face thereof to the other face thereof, adhering the intersections of the threads of said cloth with a fixative, passing an ink by capillary action from the surface of said cloth that is exposed to the surface of said cloth that lies against said panel at selected areas of the cloth to form an illustration on the surface of said cloth that lies against said panel, said illustration being viewable from the front surface of said panel.
