摘要： An adaptive control system is intended for use in conjunction with a printing press to control the setting of an ink control device that regulates the amount of ink applied to a substrate. The control system includes a controller for calculating a new setting for the ink control device based on a measured ink color value and a target ink color value. The controller has at least one gain parameter. The control system also includes a sensitivity adapter in communication with the controller. The sensitivity adapter modifies the gain parameter in response to the sensitivity of the ink control device to a correction in setting issued by the controller. The control system operates so that a measured ink color value on the substrate converges toward a target ink color value.

摘要： A method is disclosed for correction of the effects of ink back-flow and lateral flow in the inking system of a web-offset printing press. A plate coverage equation dependent on plate coverage is used to compensate for ink back-flow into the ink reservoir. An ink key distribution function is utilized to correct for the blurring effects of lateral ink spread caused by the action of vibrator rollers. A correction is also made for the ink saturation effect. The method is applicable to an ink key preset system.

摘要： A method of and apparatus for controlling the amount of ink and water supplied to the plate cylinder of a web offset press. The web offset press operates to print an image on a travelling substrate and the method includes the steps of: (A) monitoring a characteristic of the substrate; (B) changing by a known quantity the amount of ink supplied to the plate cylinder in response to said monitored characteristic; (C) monitoring the change in the characteristic after the step (B) to determine whether the density of ink supplied to the substrate has changed in response to the step (B); and (D) decreasing the amount of water supplied to the plate cylinder when the monitored characteristic does not change in response to the step (B).

摘要： A system and method for generating indicia of registration error between respective, separately adjustable printing units of a printing press, the printing units cooperating to print an image on a moving web, the system being of the type comprising a photo-optical control, having a field of view and depth-of-field, for generating output signals indicative of a predetermined relative disposition of marks on a web passing through the field of view within the dept-of-field of the photo-optical control as the web moves in relation to the printing units, and processing circuits, responsive to the photo-optical output signals, for generating signals indicative of deviations of the registration marks printed by the printing units from the predetermined relative disposition; improved wherein: the photo-optical control is disposed proximate to the printing units, and, having associated therewith an air driven stabilizer structure for maintaining the web within the depth of field by creating a Bernoulli effect.

摘要： An apparatus for applying covers to books of signatures (32) transported along a binding line includes cover feeders for feeding at least two covers (42a, 42b) upon a conveyor line and a fastening arrangement for joining the covers in substantially superimposed registration on the signatures at a covering station (20) on the binding line (15). A spacer bar (60) is supported on the conveyor line for temporarily separating the covers before they are joined to the signatures.

摘要： OOptical scanners (18, 19) mount to a press (1 to 8) and provide information to a register control system (15, 16, 17, 20) which automatically maintains color-to-color register. The same information is processed to provide signals to a scanner interface circuit (17) which controls the position of the optical scanners (18,19) to insure that they track the register patterns on the moving web (6).
