Reduction prints use the same linoleum block to print all of the colors in an image. 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. Typically, one prints from lightest to darkest color. After completion of the print, another edition can never be made because the block has been carved away during the creation process.4
Picasso is considered to be was the first artist to produce elegant reduction method linoleum prints.
