20090110420 | METHOD AND SYSTEM FOR IMPROVED CONTROL PATCH MEASUREMENT IN PRINTING SYSTEM - Printing systems, control systems, and methods are presented for controlling customer image creation in which process control patches are laterally offset from a lateral customer image boundary to mitigate adverse interaction of control patches and customer images and to improve print engine process control. | 04-30-2009 |
20090121162 | TECHNIQUE TO REMOVE SENSING ARTIFACTS FROM A LINEAR ARRAY SENSOR - Disclosed is a method and system for calibrating an image capturing sensor. The method and system include generating a test pattern on an image receiving device and measuring one or more colorimetric properties of the test pattern with an image sensor. The disclosed method and system measure the test pattern with the image sensor located in two or more different cross-process positions to determine an independent uniformity profile for the image sensor and the image rendering process. | 05-14-2009 |
20100092200 | OPTIMIZATION OF RELOAD PERFORMANCE FOR PRINTER DEVELOPMENT SYSTEMS WITH DONOR ROLLS - A method creates a printing image charge on a photoreceptor printing region of a photoreceptor within a printing apparatus and, simultaneously with the creating of the printing image charge, charges source patches on the photoreceptor outside the photoreceptor printing region. The method then transfers developer material from a donor roll to the photoreceptor. The source patches cause developer material to be removed from areas of the donor roll outside a donor roll printing region to create developer material-depleted regions. The method then reloads the donor roll with developer material using a magnetic brush and evaluates a reload function of the donor roll by characteristics of developer material on target patches with developer material in areas of the non-printing region of the photoreceptor adjacent the target patches. The method then alters the printing image charge to maintain the reload function within a predetermined range. | 04-15-2010 |
20120250063 | RASTER OUTPUT SCANNER WITH BEAM DELAY COMPENSATION TO COUNTERACT JITTER AND WIPER-INDUCED BANDING - Methods and raster output scanner (ROS) systems are presented in which beam delay values are set for an array of ROS light sources based on wiper error and jitter error with column alignment achieved at an alignment location spaced from a center of scan (COS) location toward an end of scan location (EOS) along a fast scan range of operation of the ROS. | 10-04-2012 |
20130148172 | PRINTING SYSTEM, RASTER OUPUT SCANNER, AND METHOD WITH ELECTRONIC BANDING COMPENSATION USING FACET-DEPENDENT SMILE CORRECTION - Raster Output Scanners and printing systems are presented along with methods for mitigating banding in printing systems, in which electronic banding compensation is employed using cross-process direction light source intensity banding correction profiles tailored to corresponding reflective facets of a rotating polygon. | 06-13-2013 |
20140060356 | METHODS AND SYSTEMS FOR INK-BASED DIGITAL PRINTING WITH MULTI-COMPONENT, MULTI-FUNCTIONAL FOUNTAIN SOLUTION - An Ink-based digital printing system comprises an external fluid applicator for applying multi-component, multi-functional fountain solution to a surface of an imaging plate. The plate is image wise exposed using a high power laser to remove primary components of the fountain solution from select regions of the plate according to digital image data, leaving a layer of the secondary components at said select regions. The plate is then inked with ink useful in printing. The ink adheres to the select regions from which the primary components have been removed to form an ink image. The ink image is transferred at an image transfer step wherein the secondary components enable efficient transfer of the ink to a medium with reduced image quality defects. The multi-component fountain solution comprises primary components that reject or repel ink, and secondary components that function as a release agent. | 03-06-2014 |
20140060359 | IMAGING MEMBER FOR OFFSET PRINTING APPLICATIONS - An imaging member includes a surface layer comprising a fluorosilicone and an infrared-absorbing filler. At least 75% of the siloxane units in the fluorosilicone are fluorinated. Methods of manufacturing the imaging member and processes for variably lithographic printing using the imaging member are also disclosed. | 03-06-2014 |
20140060365 | IMAGING MEMBER FOR OFFSET PRINTING APPLICATIONS - An imaging member includes a surface layer comprising a fluoroelastomer-silicone composite formed from a reaction mixture comprising a fluoroelastomer, an oxyaminosilane, and an oxysilane-terminated compound. Methods of manufacturing the imaging member and processes for variable lithographic printing using the imaging member are also disclosed. | 03-06-2014 |
20140261030 | SYSTEMS FOR APPLYING DAMPENING FLUID TO AN IMAGING MEMBER FOR INK-BASED DIGITAL PRINTING - A dampening fluid metering system includes an anilox roll configured to meter dampening fluid onto a surface of an imaging member to form a thin, uniform layer of dampening fluid for subsequent imaging by exposure to light radiation. The anilox roll is configured to form a dampening fluid layer that is uniform and has a thickness of 1 micron or less, and preferably a thickness lying in a range of 0.2 to 1 micron. | 09-18-2014 |
20150029292 | SYSTEMS FOR DAMPENING FLUID REMOVAL, VAPOR CONTROL AND RECOVERY FOR INK-BASED DIGITAL PRINTING - A system for dampening fluid recovery in an ink-based digital printing system includes a seal manifold having a front seal portion, the front seal portion having an upper wall facing the imaging surface, the upper wall being configured to define an air flow channel with the imaging surface, the upper wall being contoured to form a distance between the upper wall and the imaging surface at an evaporation location that is less than distance between the upper wall and the imaging surface at locations interposing the evaporation location and a vacuum inlet channel of the seal manifold. | 01-29-2015 |
