Publication number: 20160016414Abstract: An inkjet printer includes a stationary inkjet printhead positioned relative to a media feed direction. The printhead includes a plurality of color planes for ejecting a plurality of different inks, each color plane having a row of nozzles and each nozzle in a respective color plane being supplied with a same ink. A first ink tank containing yellow ink is in fluid communication with a first color plane of the printhead and a second ink tank containing black ink is in fluid communication with a second color plane of the printhead. The first color plane is positioned furthest upstream in the printhead with respect to the media feed direction, and the second color plane neighbors the first color plane.Type: ApplicationFiled: September 30, 2015Publication date: January 21, 2016Inventors: Jognandan Kumar Prashar, Adrian Peter Bisson, Brian Robert Brown, Mile Jurcevic, Galo David Jaramillo

Patent number: 9079403Abstract: An inkjet printer including an inkjet printhead positioned relative to a media feed direction. The printhead has a plurality of color planes for ejecting different inks, each color plane including a nozzle row defined in a nozzle face of the printhead, and each nozzle in a respective color plane being supplied with a same ink. The printhead is plumbed such that a first color plane positioned furthest upstream with respect to the media feed direction ejects yellow ink and a second color plane neighboring the first color plane ejects black ink.Type: GrantFiled: February 26, 2014Date of Patent: July 14, 2015Assignee: Memjet Technology Ltd.Inventors: Jognandan Kumar Prasher, Adrian Peter Bisson, Brian Robert Brown, Mile Jercevic, Galo David Jaramillo

Patent number: 8702206Abstract: An inkjet printer includes an inkjet printhead having a plurality of color planes for ejecting a plurality of different inks. Each color plane has a nozzle row defined in a nozzle face of the printhead and each nozzle in a respective color plane is supplied with a same ink. The printhead is plumbed such that a first color plane ejecting a first ink having a relatively low luminance is sandwiched between second and third color planes ejecting respective second and third inks having a relatively high luminance. A plurality of ink reservoirs are in fluid communication with the printhead, the ink reservoirs containing the first, second and third inks. An amount of surfactant in the first ink is at least 0.4 wt % greater than an amount of surfactant in the second and third inks.Type: GrantFiled: September 13, 2012Date of Patent: April 22, 2014Assignee: Zamtec LtdInventors: Jognandan Kumar Prashar, Adrian Peter Bisson, Brian Robert Brown, Mile Jercevic, Galo David Jaramillo

Publication number: 20140098167Abstract: A method of inkjet printing includes the steps of: (a) moving a substrate past a printhead; (b) printing a pigment-based ink onto the substrate from a first color channel of the printhead; and (c) overprinting a fixer ink onto the pigment-based ink from a second color channel of the printhead. The fixer ink is overprinted onto the pigment-based ink within a period of less than 5 ms.Type: ApplicationFiled: October 8, 2013Publication date: April 10, 2014Applicant: ZAMTEC LIMITEDInventors: Steven Adam Bernard, Roger Michael Davey, Adrian Peter Bisson
