Letterpress printing is a process in which a raised (relief) image of your art is created, this is what we refer to as a plate. Each color requires a separate plate. The plate is then locked into the press, the specified ink is applied to the press rollers which spread the ink onto the plate. The press then feeds the paper over the plate and closes, pressing the raised, inked image onto the paper creating the print. This process is repeated for each color.
