Abstract
A method of producing a printed sheet output of a printing press uses an aqueous solution, an ink, and an input sheet. The method applies aqueous solution to the input sheet to form a non-image area and an image area thereon, and contacts the non-image and image areas of the input sheet with ink. Ink is transferred substantially only to the image area to produce the printed sheet output of the printing press. A method of producing a printed web of a printing press is also disclosed.
