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.
Claims34
A method of producing a printed sheet output of a printing press using an aqueous solution, an ink, and an input sheet, the method comprising the steps of:
- selectively applying aqueous solution to the input sheet to form a non-image area and an image area thereon, wherein the non-image and image areas are undefined until the aqueous solution is applied;
- and
- contacting the non-image area having the aqueous solution and the image area of the input sheet with ink whereby ink is transferred substantially only to the image area to produce the printed sheet output of the printing press, wherein the aqueous solution in the non-image area substantially blocks transfer of the ink to the non-image area.
A method of producing a printed web of a printing press using an aqueous solution, an ink, and an input web to produce a printed output web of the printing press, the method comprising the steps of:
- selectively applying aqueous solution to the input web to form a non-image area and an image area thereon, wherein the non-image and image areas are undefined until the aqueous solution is applied;
- and
- contacting the non-image area having the aqueous solution and the image area of the input web with ink whereby ink is transferred substantially only to the image area to produce the printed output web of the printing press, wherein the aqueous solution in the non-image area substantially blocks transfer of the ink to the non-image area.
