20140290517 | LASER-ASSISTED ALIGNMENT OF MULTI-STATION FLEXOGRAPHIC PRINTING SYSTEM - A multi-station flexographic printing system includes a plurality of flexographic printing stations. Each flexographic printing station includes a flexo master. Each flexo master comprises a Fresnel zone pattern in a unique position. A method of aligning a plurality of flexographic printing stations includes printing a Fresnel zone pattern on a substrate in a unique position for each flexographic printing station. Light is directed through the Fresnel zone patterns on the substrate. The light focused by the Fresnel zone patterns is captured with a sensor device. | 10-02-2014 |
20140290518 | METHOD AND SYSTEM OF MARKING A SUBSTRATE FOR VISUAL ALIGNMENT - A multi-station flexographic printing system includes a first flexographic printing station that includes a first flexo master. The system includes one or more additional flexographic printing stations, wherein each of the one or more additional flexographic printing stations includes a flexo master. The first flexo master includes one or more alignment boxes in one or more unique positions. Each flexo master of the one or more additional flexographic printing stations includes an alignment box completion in a predetermined position. A method of marking a substrate for visual alignment includes printing one or more alignment boxes in one or more unique positions on a substrate. One or more alignment box completions are printed in one or more predetermined positions on the substrate. The one or more predetermined positions correspond to the one or more unique positions. | 10-02-2014 |
20140290519 | Wrinkle Detection In Continuous Feed Printers - A web printing system automatically detects the location of a wrinkle in a moving web. The web has a plurality of marked reference positions including an inboard position, a center position, and an outboard position. A plurality of contact image sensors detect the reference positions after the web passes through a spreader and an inboard distance and an outboard distance are respectively measured from the center position. If the inboard distance is less than a nominal inboard distance, the wrinkle is identified as inboard of the center position. If the outboard distance is less than a nominal outboard distance, the wrinkle is identified as outboard of the center position. The machine operator is notified of the fault condition and takes action to remedy the situation. | 10-02-2014 |
20140331880 | CLOSED-LOOP CONTROL OF UNTENSIONED PRODUCT LENGTH ON A WEB PRESS - A system and method is provided for closed loop control of an untensioned product length of a web moving through a printing press under tension during production. While a printing press is printing on the web, a controller receives a calculated untensioned product length L | 11-13-2014 |
20150033968 | OPTICAL ALIGNMENT OF MULTI-STATION FLEXOGRAPHIC PRINTING SYSTEM USING MOIRE INTERFERENCE - A method of aligning a multi-station flexographic printing system using Moiré interference includes printing, using a first flexographic printing station, at least one Moiré interference pattern in a unique location on a first side of a substrate for each of at least one subsequent flexographic printing stations of the system. For each of the at least one subsequent flexographic printing stations, at least one inverted Moiré interference pattern is printed on either side of the substrate in a location corresponding to that station's unique location on the substrate. An alignment of at least one of the at least one subsequent flexographic printing stations is adjusted when at least one Moiré interference pattern interferes with a corresponding at least one inverted Moiré interference pattern. | 02-05-2015 |
20150053104 | SYSTEMS AND METHODS FOR AUTOMATIC PRINT ALIGNMENT - The present application is directed to systems and methods for print alignment by a continuous feed printer. A sensor of a printer detects a first line of a pattern on a non-printing side of a printing medium, the pattern comprising two non-parallel lines separated by a predetermined distance at a predetermined position of the printing medium. The printer advances the printing medium a first distance, and the sensor detects a second line of the pattern. The printer identifies a horizontal offset of the printing medium from an expected location of the predetermined position proportional to the difference between the first distance and the predetermined distance. | 02-26-2015 |
