The commercial printing process is somewhat simple and hasn’t really changes in over a 100 years. An aluminum plate is created from the art work, each representing one color out of the CMYK process. The plate is wrapped around a plate cylinder that allows ink to fill up the cut out shape of the aluminum plate. Ink is poured into the cutout and it is transferred to a rubber roller called the blanket cylinder. The blanket cylinder is what is used to allow the paper to roll within to retrieve the right level of ink. Finally, the impression cylinder is the roller that pushes paper along at 10,000 sheets per hour to absorb the right level of ink. There are four presses, each for the individual colors. The paper moves along each press, retrieving one color at a time and finally ends up in an area of inferred heat to dry the paper for printing on the back side.
