20100118050 | NON-LINEAR IMAGE MAPPING USING A PLURALITY OF NON-LINEAR IMAGE MAPPERS OF LESSER RESOLUTION - A display system and method for displaying an image on a non-planar display that allows the images to be mapped by image mappers while encompassing image data of an adjacent sub-image or sub-images. This allows a single unified image to be displayed in real time without any tearing or positional/angular artifacts at the image boundaries. | 05-13-2010 |
20130050314 | PRINTING REGISTERED PATTERNS ON MULTIPLE MEDIA SIDES - A method of printing includes printing first and second patterns at first and second locations on first and second sides of a media using first and second printheads, respectively. First and second fiducial images including a fiducial origin are captured using first and second cameras, respectively. First and second pattern images of the first and second patterns are captured using the first and second cameras, respectively. The locations of the first and second patterns relative to the fiducial origin are determined using an image registration controller. A relative printed location of the first pattern and the second pattern is determined. A deviation is determined by comparing the determined relative location of the first and second printed patterns with an intended relative location of the first and second printed patterns. The determined deviation is compensated for by adjusting at least one of the first and second printheads so that subsequently printed first and second pattern have the intended relative print locations. | 02-28-2013 |
20130215165 | AUTOMATED PRINT AND IMAGE CAPTURE POSITION ADJUSTMENT - A first registration mark is printed by a first printhead on print media at a first initial encoder value. A second registration mark is printed by a second printhead on print media at a second initial encoder value. The second registration mark is spaced apart from the first registration mark. The first and second registration marks are detected using the mark detection system as each is transported past the mark detection system. The displacement signal is used to measure a displacement of the print media between the detection of the second and first registration marks by the mark detection system. A cue delay value is determined for the second printhead so that a subsequently printed first image plane and a second image plane are registered relative to each other using the displacement, the first initial encoder value, and the second initial encoder value. | 08-22-2013 |
20130215208 | AUTOMATED PRINT AND IMAGE CAPTURE POSITION ADJUSTMENT - A first registration mark, printed by a first printhead, includes a first crosstrack locating feature and a first guiding feature that aids an image capture device in locating the first crosstrack locating feature. A second registration mark, printed by a second printhead, includes a second crosstrack locating feature and a second guiding feature that aids the image capture device in locating the second crosstrack locating feature. The first registration mark and the second registration mark are detected using the image capture system as they are moved past the image capture system. A lateral displacement is measured between the second crosstrack registration mark and the first crosstrack registration mark using the image capture system. The lateral displacement is used to determine a lateral shift value for the second printhead to register a first image plane and a second image subsequently printed by the first printhead and second printhead. | 08-22-2013 |
20130286072 | CORRECTING WEB SKEW IN A PRINTING SYSTEM - A printing system includes multiple lineheads that each jet ink onto a print media while the print media is transported through the printing system. Imaging devices are positioned to capture one or more images of each side of the print media. A method for correcting for web skew and front-to-back registration includes determining a skew positional error for each color plane in a printing module and determining one or more skew positional correction values based on the skew positional error. A registration positional error can be determined and one or more registration positional correction values can be determined based on the registration positional error. A setting or operation of at least one printing system component is automatically adjusted based on at least one registration positional correction value or at least one skew positional correction value. | 10-31-2013 |

20140063098 | ALIGNING PRINT DATA USING MATCHING PIXEL PATTERNS - A method for aligning multi-channel digital image data for a digital printer having a plurality of printheads is described. A test pattern including test pattern indicia printed using individual printheads is scanned and analyzed to detect locations of the printed test pattern indicia. One of the printheads is designated to be a reference printhead, and one or more of the other printheads are designated to be non-reference printheads. Spatial adjustment parameters are determined for each of the non-reference printheads responsive to the detected test pattern indicia locations. Digital image data for the non-reference printheads is modified by designating an input pixel neighborhood within which an image pixel should be inserted or deleted, comparing the image pixels in the input pixel neighborhood to a plurality of predefined pixel patterns to identify a matching pixel pattern; and determining a modified pixel neighborhood responsive to the matching pixel pattern. | 03-06-2014 |
20140063099 | ALIGNING PRINT DATA FOR OVERLAPPING PRINTHEADS - A method for aligning multi-channel digital image data for a digital printer having an array of printheads for each of a plurality of channels is described. A test pattern including test pattern indicia printed using individual printheads is scanned and analyzed to detect locations of the printed test pattern indicia. For each array position, one of the printheads is designated to be a reference printhead, and one or more of the other printheads are designated to be non-reference printheads. Spatial adjustment parameters are determined for each of the non-reference printheads responsive to the detected test pattern indicia locations. Digital image data to be printed with the non-reference printheads is modified in accordance with the determined spatial adjustment parameters. | 03-06-2014 |
20140063513 | MODIFYING PRINT DATA USING MATCHING PIXEL PATTERNS - A method for aligning multi-channel digital image data for a digital printer having a plurality at least one printhead is described. One or more spatial adjustment parameters are determined for each of the printheads. The spatial adjustment parameters can be determined by comparing locations of test pattern indicia in a printed test pattern to predefined reference indicia locations. Digital image data for the non-reference printheads is modified by designating an input pixel neighborhood within which an image pixel should be inserted or deleted, comparing the image pixels in the input pixel neighborhood to a plurality of predefined pixel patterns to identify a matching pixel pattern; and determining a modified pixel neighborhood responsive to the matching pixel pattern. | 03-06-2014 |
20140118433 | WEB SKEW COMPENSATION IN A PRINTING SYSTEM - A printing system includes one or more lineheads that jet ink onto a first side of a print media. At least one roller supports a second side of the print media as the print media is transported through the printing system. A roller deformation adjustment mechanism abuts at least one roller and is configured to apply a force to the roller to deform the roller. The deformation of the roller compensates for web skew by changing the relative timing of ink flight times from the linehead to the first side of the print media. The linehead can be disposed on a movable support. The printing system can also include one or more linehead skew adjustment mechanisms configured to move the movable support to adjust a skew of the linehead. | 05-01-2014 |
