Patent number: 7295224Abstract: A model of a thermal print head is provided that models the thermal response of thermal print head elements to the provision of energy to the print head elements over time. The amount of energy to provide to each of the print head elements during a print head cycle to produce a spot having the desired density is calculated based on: (1) the desired density to be produced by the print head element during the print head cycle, (2) the predicted temperature of the print head element at the beginning of the print head cycle, (3) the ambient printer temperature at the beginning of the print head cycle, and (4) the ambient relative humidity.Type: GrantFiled: April 26, 2004Date of Patent: November 13, 2007Assignee: Polaroid CorporationInventors: Brian D. Busch, Suhail S. Saquib, William T. Vetterling

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: 7166558Abstract: 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: March 23, 2004Date of Patent: January 23, 2007Assignee: Zink Imaging, LLCInventors: Jayprakash C. Bhatt, Brian D. Busch, Daniel P. Bybell, F. Richard Cottrell, Anemarie DeYoung, Chien Liu, Stephen J. Telfer, Jay E. Thornton, William T. Vetterling

Patent number: 6842186Abstract: 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: GrantFiled: February 22, 2002Date of Patent: January 11, 2005Assignee: Polaroid CorporationInventors: Alain Bouchard, Brian D. Busch, Daniel P. Bybell, Anemarie DeYoung, Sandra B. Lawrence, Michael L. Reisch, Suhail S. Saquib, Dana F. Schuh, Stephen J. Telfer, Jay E. Thornton, William T. Vetterling, Michael S. Viola
