  • Method for minimizing banding artifacts in an ink jet printing apparatus
    Patent number: 7914097
    Abstract: A multipass printing method is characterized in that, on any given pass, the number of selected print locations onto which printing ink is deposited by each of N nozzles varies from nozzle to nozzle. The variation is governed in accordance with a weighted smoothing spline function, particularly a polynomial B-spline function of the order “j”, where j is a value equal to one less than the number of passes.
    Type: Grant
    Filed: June 21, 2007
    Date of Patent: March 29, 2011
    Assignee: E. I. du Pont de Nemours and Company
    Inventor: Cesar Leonardo Nino

  • Computer readable medium with a program for minimizing banding artifacts in an ink jet printing apparatus
    Patent number: 7513597
    Abstract: A computer readable medium contains a program for causing a printer to execute a multipass printing method characterized in that, on any given pass, the number of selected print locations onto which printing ink is deposited by each of N nozzles varies from nozzle to nozzle. The variation is governed in accordance with a weighted smoothing spline function, particularly a polynomial B-spline function of the order “j”, where j is a value equal to one less than the number of passes.

  • Ink jet printing apparatus having a programmed controller that minimizes banding artifacts
    Patent number: 7503641
    Abstract: A multipass printing apparatus is characterized by a computer-implemented controller that controls printing operation so that, on any given pass, the number of selected print locations onto which printing ink is deposited by each of N nozzles varies from nozzle to nozzle. The variation is governed in accordance with a weighted smoothing spline function, particularly a polynomial B-spline function of the order “j”, where j is a value equal to one less than the number of passes.
