Abstract

Abstract A closed loop register control system used in association with a printing press and comprising a television camera in combination with a strobe light and a solid state imaging device which enables continuous scanning of the sheet web. The apparatus of this invention also comprises a printing press console having associated therewith a digitizing tablet and a television monitor. The location of the area that is to be examined is defined by the pressman. The area to be examined may be selected by laying a proof sheet down on the digitizing tablet and recording the coordinates of the area of interest. This controls the camera and strobe light with the pressman selecting one part of the image as important and causing the register mechanism to maintain register in that selected area. Electronics then make comparisons between the detected image and a desired reference image to cause correction on a per color basis at the printing press stations.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 190 words
A closed loop register control system for providing proper register in multi-color printing in connection with a moving web or sheet substrate having a multicolor image thereon adapted to pass a monitoring station, said system comprising, a television receiver at the monitoring station adapted to be positioned to view any segment of the multi-color image, means for positioning the television receiver including means for receiving a control signal to provide adjustment of the television receiver relative to the substrate to permit observation of any point of the multi-color image, means under operator control for generating a coordinate control signal for carrying out the adjustment, means for electronically storing a position signal corresponding to any reference color dot of the multi-color image as observed by the television receiver, means for electronically storing position signals corresponding to at least one other color dot observed by the television receiver, means establishing a predetermined desired interpositional signal, means for comparing the electronically observed relative position signals with the desired interpositional signal to determine if adjustment is necessary and means for providing automatic substrate position correction in the event of a correction signal being generated.
Claim 2
Dependent Claim 190 words
A closed loop register control system for providing proper register in multi-color printing in connection with a moving web or sheet substrate having a multicolor image thereon adapted to pass a monitoring station, said system comprising, a television receiver at the monitoring station adapted to be positioned to view any segment of the multi-color image, means for positioning the television receiver including means for receiving a control signal to provide adjustment of the television receiver relative to the substrate to permit observation of any point of the multi-color image, means under operator control for generating a coordinate control signal for carrying out the adjustment, means for electronically storing a position signal corresponding to any reference color dot of the multi-color image as observed by the television receiver, means for electronically storing position signals corresponding to at least one other color dot observed by the television receiver, means establishing a predetermined desired interpositional signal, means for comparing the electronically observed relative position signals with the desired interpositional signal to determine if adjustment is necessary and means for providing automatic substrate position correction in the event of a correction signal being generated.
Claim 3
Dependent Claim 24 words
A closed loop register control system as set forth in claim 1 wherein said means for positioning the television receiver includes motor control means.
Claim 4
Dependent Claim 26 words
A closed loop register control system as set forth in claim 2 including strobe light means associated with the television receiver for providing an optical aperture.
Claim 5
Dependent Claim 25 words
A closed loop register control system as set forth in claim 3 wherein said means for generating a coordinate control signal includes a digitizing tablet.
Claim 6
Dependent Claim 23 words
A closed loop register control system as set forth in claim 4 including a sample or proof sheet associated with the digitizing tablet.
Claim 7
Dependent Claim 21 words
A closed loop register control system as set forth in claim 5 including a television monitor associated with the digitizing tablet.
Claim 8
Dependent Claim 154 words
A closed loop register control system for providing proper register in multi-color printing in connection with a moving web or sheet substrate having a multi-color image thereon adapted to pass a monitoring station, said system comprising, a television receiver at the monitoring station adapted to be positioned to view any segment of the substrate multi-color image, means for positioning the television receiver including means for receiving a control signal to provide adjustment of the television receiver relative to the substrate, means under operator control for generating a coordinate control signal for carrying out the adjustment, means for establishing and electronically storing a reference position for a reference series of dots from any series of dots comprising the image, means for electronically storing position signals corresponding to at least one other series of color dots and means for comparing the electronically stored relative position signals with desired interpositional signals to provide automatic substrate position corrections.
Claim 9
Dependent Claim 154 words
A closed loop register control system for providing proper register in multi-color printing in connection with a moving web or sheet substrate having a multi-color image thereon adapted to pass a monitoring station, said system comprising, a television receiver at the monitoring station adapted to be positioned to view any segment of the substrate multi-color image, means for positioning the television receiver including means for receiving a control signal to provide adjustment of the television receiver relative to the substrate, means under operator control for generating a coordinate control signal for carrying out the adjustment, means for establishing and electronically storing a reference position for a reference series of dots from any series of dots comprising the image, means for electronically storing position signals corresponding to at least one other series of color dots and means for comparing the electronically stored relative position signals with desired interpositional signals to provide automatic substrate position corrections.
Claim 10
Independent Claim 126 words
A method for providing a closed loop register control to in turn provide proper register in multi-color printing in connection with a moving web sheet substrate having a multi-color image thereon, said method comprising the steps of providing a television receiver, under operator control positioning the television receiver so as to view a desired segment of the substrate, electronically storing a position signal corresponding to any reference color dot in the multi-color image, electronically storing a position signal corresponding to at least one other color dot, establishing a predetermined desired interpositional signal, and comparing the electronically stored relative position signals with the desired interpositional signal to determine if adjustment is necessary and providing automatic substrate position correction in the event of a correction signal being generated.
Claim 11
Independent Claim 126 words
A method for providing a closed loop register control to in turn provide proper register in multi-color printing in connection with a moving web sheet substrate having a multi-color image thereon, said method comprising the steps of providing a television receiver, under operator control positioning the television receiver so as to view a desired segment of the substrate, electronically storing a position signal corresponding to any reference color dot in the multi-color image, electronically storing a position signal corresponding to at least one other color dot, establishing a predetermined desired interpositional signal, and comparing the electronically stored relative position signals with the desired interpositional signal to determine if adjustment is necessary and providing automatic substrate position correction in the event of a correction signal being generated.
