This image is an example of a collagraph made by building up layers of acrylic mediums and sand on a piece of cardboard.  Printing is done in one pass through the press.  

I call the printing technique relief and intaglio.  Colors are applied by wiping the first color in the usual intaglio manner (in this case, blue.) Subsequent colors are applied and removed with rollers of differing durometer (range of hard to soft). Editions for this technique can be quite variable.
