Method And Apparatus For Visually Inspecting A Substrate On A Printing Press

View page
US Patent:
20040188644, Sep 30, 2004
Filed:
Apr 9, 2004
Appl. No.:
10/821320
Inventors:
Jeffrey Rappette - Waukesha WI, US
Andrew Tischendorf - Campbellsport WI, US
Mark Gerloff - New Berlin WI, US
Arie Rechavel - Glendale WI, US
Edward Boris - Cedarburg WI, US
Frank Vroman - Cedarburg WI, US
Michael Sisco - Sussex WI, US
Paul Warner - West Bend WI, US
Assignee:
Quad/Tech, Inc. - Sussex WI
International Classification:
B41F031/02
G01V008/00
H01L027/00
US Classification:
250/559440, 250/208100
Abstract:
The present invention relates generally to the field of printing presses, and specifically to a method and apparatus for visually inspecting a web moving on a printing press using a CMOS based image recording device and preferably a LED light source. The LED light source includes at least two colors of light, such as white and blue, for highlighting various ink colors with respect to the web.

System And Method For Monitoring Color In A Printing Press

View page
US Patent:
57242593, Mar 3, 1998
Filed:
May 4, 1995
Appl. No.:
8/434928
Inventors:
John C. Seymour - Jefferson WI
Jeffrey P. Rappette - Waukesha WI
Frank N. Vroman - Cedarburg WI
Chia-Lin Chu - Brookfield WI
Bradly S. Moersfelder - Waukesha WI
Michael A. Gill - Oconomowoc WI
Karl R. Voss - Wauwatosa WI
Assignee:
Quad/Tech, Inc. - Sussex WI
International Classification:
G01N 2147
G01N 2188
G06F 1500
US Classification:
364526
Abstract:
A method for monitoring color of a printed image printed on a substrate, the method comprising the steps of: positioning a camera assembly to receive light reflected from the printed image on the substrate, the camera assembly including a structure for producing a signal; transmitting the signal from the camera assembly to a computer; and processing the signal in the computer to correct for the effects of scattered light reflected from the printed image.

Method For Elimination Of Effects Of Imperfections On Color Measurements

View page
US Patent:
61782548, Jan 23, 2001
Filed:
May 29, 1998
Appl. No.:
9/087475
Inventors:
Jeffrey P. Rappette - Waukesha WI
John C. Seymour - Jefferson WI
Assignee:
Quad/Graphics, Inc. - Sussex WI
International Classification:
G06K 900
US Classification:
382112
Abstract:
A method for monitoring the color quality of color patches printed on a web is disclosed. The method includes the steps of using an imaging device to receive light reflected from the printed image on the substrate to produce a signal. The signal is transmitted from the imaging device to a computer and processed in the computer. Processing the signal in the computer includes the steps of digitizing the signal to produce a digitized array of pixels, each pixel having an associated color value, determining a portion of the pixels within the digitized array corresponding to the color patch, determining an acceptable range of color values for the pixels in the portion of the pixels, determining for each pixel in the portion of pixels whether the color value is within the acceptable range, and computing an aggregate color value for the color patch by averaging the color values of each pixel in the portion of pixels including only those color values within the acceptable range.

US Patent:
56894252, Nov 18, 1997
Filed:
Apr 27, 1995
Appl. No.:
8/429910
Inventors:
Jeffrey W. Sainio - Glendale WI
John C. Seymour - Jefferson WI
Jeffrey Paul Rappette - Waukesha WI
Chia-Lin Chu - Brookfield WI
Assignee:
Quad/Tech, Inc. - Sussex WI
International Classification:
G06F 1900
US Classification:
36446903
Abstract:
A control system is disclosed for controlling misregistration between the colors of an image printed on a web. The system includes an imaging device such as a camera or group of cameras, a processor, and image conversion circuits coupled to the processor. The system detects print color misregistration based upon the signals produced by the imaging device as a result of scanning the printed image. The conversion circuits convert the signals to signals usable by the processor to determine the color densities of the various colors within the image. These on-press color densities are compared with reference color densities stored in a memory of the processor, wherein the reference color densities may be generated from a source such as the printing plates used to print the image for which misregistration is being monitored. Based upon the phase correlation of the on-press images with the reference images, a processor operates to produce registration offset values between the printed colors and controls a print controller which adjusts the print units such that the colors of the printed image are placed into registration.
