Patent number: 7635660Abstract: A multicolor imaging system is described wherein at least two, and preferably three, different image-forming layers of a thermal imaging member are addressed at least partially independently by a thermal printhead or printheads from the same surface of the imaging member by controlling the temperature of the thermal printhead(s) and the time thermal energy is applied to the image-forming layers. Each color of the thermal imaging member can be printed alone or in selectable proportion to the other color(s). Novel thermal imaging members are also described.Type: GrantFiled: April 3, 2006Date of Patent: December 22, 2009Assignee: Zink Imaging, Inc.Inventors: Jayprakash C. Bhatt, Daniel P. Bybell, F.

Publication number: 20090128613Abstract: A thermal printer is disclosed which includes a plurality of thermal print heads, each of the plurality of thermal print heads being operable to print a distinct one of a plurality of colors. The plurality of thermal print heads may print output at a plurality of spatial resolutions. The thermal printer may include dot size varying means for varying perceived levels of color printed by the thermal printer by varying sizes of dots printed by the plurality of thermal print heads. The printer may perform various image processing steps on an image to be printed, such as tone scale adjustment, thermal history control, and common mode voltage correction, to improve the perceived quality of the printed image. The thermal printer may be incorporated into a digital photo-printing vending machine for printing images provided by a customer.Type: ApplicationFiled: November 14, 2008Publication date: May 21, 2009Inventors: Alain Bouchard, Brian D.

Patent number: 7207645Abstract: Techniques are disclosed for performing color correction in a color printer. An RGB test image is printed to produce a printed calibration image. Colors in the printed calibration image are measured and compared to expected color values. A color corrector generates a printer lookup table (LUT) based on this comparison. The LUT may be generated based on models of the printer's print engine and previous LUTs. The color corrections are applied to subsequent print jobs to improve the quality of color output. Color measurement and correction may be performed using a closed-loop system contained within the printer that includes a color measurement device (such as a scanner) and a computer.Type: GrantFiled: April 6, 2004Date of Patent: April 24, 2007Inventors: Brian D. Busch, Daniel P. Bybell, William J. Donovan, Felix J. Lin, Suhail S. Saquib, Jay E. Thornton

Patent number: 6999202Abstract: In one aspect of the present invention, a method is provided for producing a halftone of a source image. The halftone includes halftone pixels. The halftone pixels are suitable for containing halftone dots. The method selects glyphs corresponding to intensities of regions (e.g., pixels) in the source image. The glyphs contain one or more halftone dots. The method locates halftone dots within the halftone pixels such that for at least one pair of halftone dots contained within a pair of halftone pixels sharing a common boundary, the halftone dots in the pair of halftone pixels extend in opposite directions from the common boundary.Type: GrantFiled: March 27, 2001Date of Patent: February 14, 2006Assignee: Polaroid CorporationInventors: Daniel P.

Patent number: 5221971Abstract: Printing apparatus and method particularly suited to provide a hardcopy of an image which is produced by medical imaging equipment or the like. The apparatus produces hardcopy consisting of pixels whose size can be changed by area modulation to suit image tonal content and detail while still maintaining a large number of gray levels per area modulation cell (pixel). Preferably, the same area modulation patterns representing pixel tonal values are used for printing pixels of different sizes.Type: GrantFiled: November 21, 1990Date of Patent: June 22, 1993Assignee: Polaroid CorporationInventors: Janet A.
