The process starts with carving a design into a new lino block and printing the first color on each sheet of paper in the edition. Then the printmaker carves more of the same block away and proceeds to print the second color. The process of carving and printing continues for each additional color until the final layer is printed. After completion of the print, another edition can never be made because the block has been carved away during the creation process.
