Publication number: 20210053361Abstract: A first input color channel value for a first colorant and a second input color channel value for a second colorant are received. A first number of drops of a first colorant is obtained based on the first input color channel value and a first drop sequence. A second number of drops of a second colorant is obtained based on the second input color channel value and a second drop sequence. The first drop sequence defines a first mapping between input color channel values and number of drops and the second drop sequence defines a second, different, mapping between input color channel values and number of drops.Type: ApplicationFiled: March 29, 2018Publication date: February 25, 2021Applicant: Hewlett-Packard Development Company, L.P.Inventors: Juan SAEZ GOMEZ, Michel GEORGES ENCRENAZ, Fernando CHICA AGUILERA

Patent number: 10747486Abstract: Web server based color management hosted by a web server is provided enabling a production device to produce a print job with a similar color appearance as a reference device. The web server receives a production device color management profile and a reference device color management profile. The web server creates an output color management profile based on the color management profile of the production device and the color management profile of the reference device. The output color management profile maps device-independent color values associated in the color management profile of the reference device to device-specific color values for colors reproducible by the production device.Type: GrantFiled: July 28, 2016Date of Patent: August 18, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Michel Georges Encrenaz, Josep Abad Peiro

Patent number: 10200568Abstract: Described herein are systems and methods for processing an image such as a halftone image. For example, in some embodiments, pixels of an image are checked to see if when printed would be represented by a given output. Pixels of the image that match defined values are replaced with pixels that are represented by a different set of outputs. This latter set of outputs may be selected to optimize one or more imaging attributes.Type: GrantFiled: November 3, 2014Date of Patent: February 5, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Michel Georges Encrenaz, Peter Morovic, Johan Maurice Lammens, Jan Morovic
