    摘要： In the illustrated embodiment a rotary position detector utilizes an angularly adjustable light conduit for selecting the angle of the input shaft at which a reference signal is generated. In a web register control system where an analog error signal is to be generated according to any lack of coincidence between the reference signal and a scanner signal, such analog error signal can be utilized during set up (with the web properly registered) for automatic positioning of the light conduit at the angle required to define the register condition of the system.

    摘要： A system is disclosed for indicating and controlling register between repetitive patterns of work applied to a moving web, wherein a digital encoder is rotated in synchronism with rotation of work-performing members, and by counting encoder pulses any error in register at respective work stations may be displayed and/or utilized for automatic control purposes. Counter circuitry is utilized both to facilitate set up of the system and to provide a precisely adjustable digital set point for error determination in operation. Provision is made for a high error sampling rate for automatic control and a lower error sampling rate for digital display. A digital display of average error is an alternative to a lower error sampling rate.

    摘要： In web-fed, multicolor printing operations wherein individual colors which make up the final composite copy are separately applied to the web, each at a separate printing unit or station, the invention provides a new and advantageous method of controlling the color densities and tones obtained in said composite copy, so that they closely correspond to those of the original art work or composition to be reproduced. The method provided employs electrical energy of controlled relatively high voltage and low amperage which is applied in the area of each printing unit or station wherein said individual colors are transferred to the web, whereby to effect or assist said transfer. It further provides for separately regulating the potential of the electrical energy supplied to each of the separate printing units or stations, to govern the amount of pigment there transferred to the web and thereby independently control the density of each individual color in the composite copy. By controlling the density of each individual color applied to the web, the tone values of combined colors in the copy (such as, for example, a purple formed by overprinting blue on red) may also be controlled.
