ABSTRACT:
An engraving board for printing a design with coloring media comprising, a first or thick paper layer with a second or thinner paper layer overlaying the thick paper layer and secured thereto. A printing layer comprising a multiplicity of densely packed short fibers overlays the thin paper layer and is secured thereto. The three layers can be secured to each other by means of water resistant adhesive and both the thinner and thick paper layers can comprise water absorbent material so that when a design is impressed upon the printing layer, exposing a portion of the thin paper layer, the coloring medium which is applied over the engraving board is absorbed into a thinner paper layer leaving the coloring medium on the remaining printing layer only to be used in printing the design.
