How is printmaking relative to Graphic Design?

As a graphic designer, you may design some pieces that are to be printed, so a knowledge of how the process works is needed. Also, many times a design will look great on screen, all designers need to look at a print (hard copy) of the design to identify areas where there may be a problem. Printmaking often refers to the process of an artist who makes plates, wood cuts or etchings and also does the actual printing.
