Claim 2:
3. In combination, an artist's painting substrate and artists' alcohol inks applied to the surface of the substrate, comprising:
a stiff board having two opposed sides, of thickness in the range of at least about 1/16 inch, the board being fiberboard,
a vinyl plastic film mounted and adhered onto one side of the board, with the alcohol inks applied directly on the surface of the vinyl plastic film,
the vinyl plastic film having a roughness surface characteristic without ink, exhibiting a root-mean-square roughness of Sq in a range of about 6 to 12 microns, and
such that the vinyl plastic film surface interacts with the alcohol inks applied to the surface so as to create controlled artistic effects by the ink-gripping and absorptive qualities of the vinyl plastic surface.
