Abstract: A mechanism for sorting sheets from a printing press to assure proper color density and to assist in making corrective adjustment which includes a main conveyor for normally conducting sheets to a main delivery pile and having a transfer station. An auxiliary conveyor extends from the transfer station to an auxiliary delivery pile. A scanning device is arranged upstream of the main conveyor for responding to the color density of the printed image on a passing sheet. A comparator produces a control signal when the color density is above or below tolerance, signifying a sub-quality sheet. Mechanism at the transfer station is triggered by the control signal so that the sub-quality sheet is diverted to the auxiliary conveyor for depositing on the auxiliary pile. The mechanism not only accomplishes sorting but the fact of diversion and the observed rate of diversion provides constant instruction to the pressman as to the necessity for, and the degree of, a corrective change in ink feed rate.
