Printing Related Environmental Training As the plate cylinder
rotates, the plate comes in contact with the dampening rollers
first. The dampening rollers wet the plate so the non-printing
areas repel ink. Then the inking rollers transfer ink to the
dampened plate, where ink only adheres to the image areas. The
inked image is transferred to the rubber blanket, and the
substrate is printed as it passes between the blanket and
impression cylinder. There are three basic lithographic press
designs: unit-design, common impression cylinder design, and
blanket-to-blanket design. The unit-design press is a self-
contained printing station consisting of a plate cylinder, a
blanket cylinder, and an impression cylinder. Two or more
stations may be joined to perform multi-color printing. A common
impression cylinder press consists of two or more sets of plate
and blanket cylinders sharing a common impress
