Patent number: 7965409Abstract: A method and system are proposed in which a moving window based operator is applied to a page of a PDL document that has been decomposed, and the objects within the page flattened and rasterized. The window moves along the raster scan line, and processes rasterized data within the window, detecting any color-to-white or white-to-color interface (edge). The white rasterized portion is then dilated outward across the interface into the color portion, the dilated amount being based on a size of a reverse fine line and/or small text font character to be reproduced. A size of the fine line and/or small text font object is determined and if below a threshold, object dilation may be given effect. A dilation amount may increase as the object size decreases until the size reaches a lower threshold at and beyond which a maximum dilation amount may be applied.Type: GrantFiled: December 17, 2007Date of Patent: June 21, 2011Assignee: Xerox CorporationInventor: Guo-Yau Lin

Patent number: 7965414Abstract: An approach for detecting and correcting printing system print quality defects is disclosed that allows defects to be corrected based on an analysis of image data collected over time, across many separate images, under a wide variety of system status and environmental conditions to allow detection of print quality defects that would otherwise be undetectable. The approach supports the detection and correction of defects related to colorant appearance effects that are correlated to colorant interactions. Techniques are described by which allow image data to be efficiently collected and stored to support a wide range of defect processing techniques. Defect processing may be performed in parallel with print job operations using spare processor CPU cycles and/or may be performed off-line by either the printing system processor or a separate defect processing system. Detected print quality defects may be corrected for using one or more interpolation techniques.Type: GrantFiled: January 23, 2008Date of Patent: June 21, 2011Assignee: Xerox CorporationInventors: Wencheng Wu, Jing Wang

Patent number: 7965422Abstract: A system facilitates printing of microtext. A processing component allows a user to create one or more microtext characters, wherein the characters are output as a data packet. An SRE code store receives and associates one or more SRE codes with the data packet, each SRE code is representative of a bit pattern, wherein the bit pattern is a grid of bits that are filled to create a particular pattern. A font bank receives the one or more SRE codes from the SRE code store and defines such codes via a font. A raster image processor receives the font from the font bank, decodes the font and outputs instructions to print the microtext.Type: GrantFiled: April 28, 2006Date of Patent: June 21, 2011Assignee: Xerox CorporationInventors: Charles M.

Patent number: 7965410Abstract: This is a system for maximizing the use of colors in cartridges of a color marking system. By controlling the amounts of each color dispensed where the least abundant color is conserved, the life of the cartridge is extended. A sensor tells the system what amounts of each colors remain in the system, and a dispenser controller uses and dispenses the most abundant colors first, preserving the least abundant color necessary to achieve a desired colored marking. GCR (gray component replacement) is used as the fundamental scheme to control the colorants. GCR-like scheme is used for interchanging a particular non-traditional colorant and multiple conventional colorants that make such color.Type: GrantFiled: June 2, 2006Date of Patent: June 21, 2011Assignee: Xerox CorporationInventors: Guo-Yau Lin, Gerald S.

Patent number: 7963694Abstract: A temperature sensitive label may be affixed to a temperature sensitive item. The temperature sensitive label conveys when the item has reached a tripping temperature. The tripping temperature may be a temperature at which the item is compromised. To convey this, the label changes properties and functions with a message to convey that the item has been exposed to the tripping temperature. For example, the label may reveal, block, or alter a message that conveys whether the item has been exposed to the tripping temperature. The message may be part of the label or separate from the label.Type: GrantFiled: September 2, 2009Date of Patent: June 21, 2011Assignee: Xerox CorporationInventors: Gerardo Leute, Paul Kevin Acquaviva
