20140245914 | METHOD OF MOUNTING A FLEXOGRAPHIC PRINTING PLATE TO AVOID BANDING - A method of mounting a flexographic printing plate includes disposing a backing tape on a printing plate cylinder forming a taped printing plate cylinder. A transverse center of the flexographic printing plate is attached to the taped printing plate cylinder at a mount line offset relative to a scribe line of the printing plate cylinder. A first portion of the flexographic printing plate is wrapped around a first portion of the taped printing plate cylinder from the mount line outward in a first direction away from the mount line. A second portion of the flexographic printing plate is wrapped around a second portion of the taped printing plate cylinder from the mount line outward in a second direction away from the mount line. The mount line is offset relative to the scribe line at a distance that ensures banding occurs in a non-patterned non-printing area of the flexographic printing plate. | 09-04-2014 |
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 |
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 |

20150122138 | METHODS OF MANUFACTURE AND USE OF CUSTOMIZED FLEXOMASTER PATTERNS FOR FLEXOGRAPHIC PRINTING - A method of flexographically printing a uniform pattern on a substrate where the ink deposited on the substrate is deposited in the intended location and not in unintended locations. A flexo-master comprises a pattern formed by a plurality of lines including at least one junction, and printing the pattern including the at least one junction in ink on a substrate forming a printed pattern, wherein the printed junction has a different shape than the at least one junction on the flexo-master. In addition to the junction formation, a discontinuous line on the flexo-master may be used to print a continuous line, a single line may be used to print two lines, and two or more lines may be used to print a single line. The flexo-master pattern lines may additionally have a fill pattern comprising various geometries that are used to uniformly print the pattern on the substrate. | 05-07-2015 |

20120223683 | ADDRESS-SELECTABLE CHARGING OF CAPACITIVE DEVICES - A drive circuit for a capacitive device that comprises a first operational state and a second operational state. The drive circuit comprises a capacitor and preferably two or more transistors. The capacitive device is caused to transition from a first operational state to a second operational state by a row pulse being asserted on a row line and a column pulse asserted on a column enable signal commensurate with the assertion of the row pulse. If the column pulse is deasserted before the row pulse is deasserted, the capacitive device is caused to transition from the first operational state to the second operational upon deassertion of the row pulse. In some embodiments, a precisely controlled variable voltage can be applied to the capacitive device. | 09-06-2012 |
20140242294 | METHOD OF MANUFACTURING A RESISTIVE TOUCH SENSOR CIRCUIT BY FLEXOGRAPHIC PRINTING - Method of manufacturing a resistive touch sensor circuit using a roll to roll process to print microscopic patterns on a single side of at least one flexible dielectric substrate using a plurality of flexo-masters to print the microscopic patterns which are then plated to form conductive microscopic patterns. | 08-28-2014 |
20140295063 | METHOD OF MANUFACTURING A CAPACATIVE TOUCH SENSOR CIRCUIT USING A ROLL-TO-ROLL PROCESS TO PRINT A CONDUCTIVE MICROSCOPIC PATTERNS ON A FLEXIBLE DIELECTRIC SUBSTRATE - Mutual capacitance touch sensor circuits are used in manufacturing displays, including touch screen displays, such as LED, LCD, plasma, 3D, and other displays used in computing as well as stationary and portable electronic devices. A flexographic printing process may be used, for example, in a roll to roll handling system to print geometric patterns on a substrate, for example, a flexible dielectric substrate. These patterns may then be coated with a conductive material by, for example, an electroless plating process. | 10-02-2014 |
