This is one of the most difficult relief print processes. One block is used to print many colors. The lighest color and the broadest area is printed first and then the darker colors, one at a time, are carved out of the block and printed. As the artist is continually removing material from the matrix(Plate, stone, block, screen that is used to print individual impressions)to print the next color, the matrix is destroyed in the processes of making the image; hence there is no way to correct a mistake. The edition size is determined by how many acceptable impressions exist after the final color is printed. Done in 2001-This is the technical definition of reduction relief. My piece 'Flora' is also a relief print, but I only used one color, black. Basically relief is making your own stamp out of wood, linoleum or other materials. Fun fun to do!!!
