US Patent:

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.

Assignee:

The Boeing Company - Chicago IL

International Classification:

B41J 2/045
B41J 11/00

Abstract:

Systems, apparatuses and methods provides for technology that applies, with a printhead of a printing system, ink to a substrate as the substrate remains stationary and the printhead moves across the substrate. The technology determines, with a distance encoder, a distance that the printhead has moved, and controls application of the ink from the printhead to the substrate based on the distance.

Assignee:

The Boeing Company - Chicago IL

International Classification:

C23F 1/08
B33Y 40/00
B05C 5/00
C23F 1/02

Abstract:

A method of micro-texturing a surface is disclosed. The method includes printing an etchant onto a substrate surface and forming a micro-texture on the substrate surface by removing material from the substrate surface.

B33Y 40/00
B05C 5/00

Abstract:

A method of micro-texturing a substrate surface is disclosed, including printing a maskant on the substrate surface to define exposed surface zones on the substrate surface. The method further includes forming a micro-texture on the substrate surface by removing material from the exposed surface zones, and removing the maskant from the substrate surface.

International Classification:

H04N 1/60
G06F 3/12

Abstract:

A method includes receiving information specifying a color gamut. The color gamut corresponds to a range of colors producible by an output device. The method further includes receiving a first indication of a first color associated with a first point in a geometrical representation of the color gamut in a three-dimensional (3D) color space. The method further includes generating, based on the first color, a second indication of a second color that is included in the color gamut. The second color is associated with a second point in the 3D color space. The second point is identified based on a particular value of data associated with a plurality of distances between the first point and a subset of points of the geometrical representation. The subset of points includes more than one and fewer than all points of the geometrical representation.
