US Patent:

20220339947, Oct 27, 2022

Filed:

Jul 6, 2022

Appl. No.:

17/811049

Inventors:

- Chicago IL, US
Kjersta Lynn Larson-Smith - Seattle WA, US
Edward Greene - Charleston SC, US
Raj A. Desai - Seattle WA, US

International Classification:

B41J 2/18
B41J 3/407
B41J 2/175
B41J 2/07

Abstract:

Inkjet printing systems and methods dynamically control meniscus pressure at a nozzle to more reliably deliver ink to a substrate. The systems and methods include inferring an angle of a longitudinal axis of a printhead relative to the vertical reference axis based on an orientation signal from an orientation sensor, determining a target feed fluid pressure upstream of the nozzle and a target recirculation fluid pressure downstream of the nozzle, thereby to maintain a target pressure differentiation across the nozzle based, at least in part, on the inferred angle of the longitudinal axis, and controlling a variable feed pump speed and a variable recirculation pump speed to obtain the target feed fluid pressure and the target recirculation fluid pressure.

Abstract:

A method, apparatus, system, and computer program product for applying a color to an aircraft. The color for an exterior surface of the aircraft is determined by the computer system from a design of the aircraft. A position of the color in three-dimensional space is determined by the computer system. The position is in a color space coordinate system. An inkjet printer in the inkjet printers with a point cloud in the plurality of point clouds having a smallest Euclidean distance to the position of the color is selected by the computer system. The inkjet printer is used to apply the color on the exterior surface of the aircraft.
