ABSTRACT:
A method of determining printing-ink consumption in an offset printing press includes feeding printing ink to an inking unit of a printing press via an ink duct having adjustable ink-gap openings, and via an ink-duct roller which absorbs the ink emerging from the ink-gap openings; determining ink-film thicknesses (s.sub.F) from the ink-gap openings, and ink-strip length (l.sub.F) and ink-strip width (b.sub.F) per unit time from the rotational speed of the ink-duct roller, and calculating therewith the quantity of printing ink supplied per unit time of per number of printed products in accordance with the equation
