Patent number: 9621762Abstract: A printing system is disclosed. The printing system includes a halftone calibration system that receives one or more un-calibrated halftones, generates one or more calibrated halftones using an ink model from the one or more un-calibrated halftones, analyzes a printed calibration screen of the one or more calibrated halftones, and performs a halftone calibration.Type: GrantFiled: January 9, 2012Date of Patent: April 11, 2017Assignee: Ricoh Company, Ltd.Inventors: Kartheek Chandu, Larry Ernst, Sreenath Rao Vantaram, Mikel J.

Patent number: 8625161Abstract: Digital halftoning processes for producing a halftone image include, for each pixel in the image: indexing a two-dimensional look up table using a position of the pixel, identifying a threshold value for the pixel from the two-dimensional look up table, creating an index that indexes a three-dimensional lookup table using the threshold value and the position of the pixel, and obtaining an output value for the pixel from the three-dimensional look up table via the index. The digital halftoning processes also produce a halftone representation of the image from output values for corresponding pixels.Type: GrantFiled: November 19, 2009Date of Patent: January 7, 2014Assignee: International Business Machines CorporationInventors: Larry Ernst, Tadanobu Inoue, Mikel Stanich, Chai W.

Publication number: 20070253017Abstract: A printer output coverage estimation system permits a user of print services to obtain an accurate estimate of the amount of toner required by a print job. Providers of print services, including coverage estimations, may be identified through the Internet and selected by the user from a web interface. The estimate request may then be transmitted directly to the provider that fulfills the request using excess computing capacity. Alternatively, providers may register excess computing capacity with a broker. The broker matches job requests with a grid of providers and directs the job request to the matched provider(s). Thus, users of print services have an alternative to purchasing in-house computing resources that may remain idle much of the time.Type: ApplicationFiled: April 28, 2006Publication date: November 1, 2007Applicant: International Business Machines CorporationInventors: Joseph Czyszczewski, Larry Ernst, Mark Finlan, James Smith
