Lance Cleveland: Maximum-diagonal print mask and multipass printing modes, for high quality and high throughput with liquid-base inks. Hewlett Packard Company, October 14, 1997: US05677716 (93 worldwide citation)

Images are printed by marks formed in pixel arrays by a scanning print head. During each scan marks are made in a pattern that approximates at least portions of many parallel, separated lines--angled steeply (best at about 3:1 slope, or at least much greater than 1:1) to the scanning axis and shallo ...

Images are printed using marks formed in pixel arrays by a scanning print head. For transparent and glossy media, with poor absorbance, drying is enhanced by a multipass (preferably six-pass) print mode in which the total number of ink drops or spots is allocated among correspondingly multiple masks ...

Ronald A Askeland, Catherine B Hunt, Keshava A Prasad, Corrina A E Hall, Mark S Hickman, Lance Cleveland, William J Allen: Inking for color-inkjet printers, using non-integral drop averages, media varying inking, or more than two drops per pixel. Hewlett Packard Company, January 16, 1996: US05485180 (9 worldwide citation)

At least one certain primary or secondary color is established that receives special treatment for at least one printing medium. Such treatment may include (1) using more than two drops of primaries per pixel for binary printing of a particular secondary; or (2) binary-printing the chromatic primary ...

W Wistar Rhoads, Lance Cleveland, Abdolreza Movaghar: Black text quality in printers using multiple black and color pens. Hewlett Packard Company, Dennis G Stenstrom, October 3, 1995: US05455607 (9 worldwide citation)

Color inkjet printers commonly employ a plurality of print cartridges, usually either two or four, mounted in the printer carriage to produce a full spectrum of colors. In order to optimize print quality, it is desirable to minimize the distance between a thermal inkjet printhead and the media that ...

Lance Cleveland: End-of-page advance-distance decrease, in liquid-ink printers. February 1, 2005: US06848765 (6 worldwide citation)

Two printing-medium guide systems restrain the medium. One is in an area upstream (along the direction of medium advance) from the pen, and extending laterally across the width of the medium except in one or more regions that are laterally near the engagement of a print-medium advancing device. The ...

Lance Cleveland: Moving node wave isolator for drafting plotters. Hewlett Packard Company, William J Bethurum, April 5, 1988: US04734987 (4 worldwide citation)

A wave isolator (18) is provided for large format drafting plotters (10) for preventing waves in the drafting medium (16) from traveling up the platen (14) and adversely affecting the pen (20) and its operation and reducing acceleration related vertical scalloping of angled lines. Such waves in the ...
