Publication number: 20210310188Abstract: In an example of a textile printing method, a thermally curable ink composition is applied on a fabric substrate. The thermally curable ink composition includes from about 1 wt % active to about 6 wt % active of a pigment that absorbs ultraviolet radiation, infrared radiation, or a combination thereof, based on a total weight of the thermally curable ink composition; from about 2 wt % active to about 20 wt % active of a polymeric binder, based on the total weight of the thermally curable ink composition; and an aqueous ink vehicle. In the method, the pigment of the thermally curable ink composition is selectively heated on the fabric substrate by exposing the fabric substrate to an emission wavelength from a narrow wavelength light source for a total exposure time of 3 seconds or less. The selective heating thermally fixes the pigment to the fabric substrate.Type: ApplicationFiled: November 29, 2018Publication date: October 7, 2021Inventors: Ronald A. Askeland, Blair A.

Patent number: 9931847Abstract: A printer is disclosed herein. The printer has a printhead having a plurality of ink nozzles for ejecting ink, a servicing mechanism for capturing the ejected ink from the ink nozzles, to service the printhead, and a control device coupled to the printhead and the servicing mechanism for regulating the servicing. As part of the regulation, the control device continues feeding a substrate towards the printhead during an idle period. The idle period of the printhead can be a duration when printing on the substrate is suspended. Further, the control device regulates ejection of ink from the ink nozzles towards the substrate during the idle period and operates the servicing mechanism during the idle period. In an example, the servicing mechanism captures the ink before the ink reaches the substrate.Type: GrantFiled: July 31, 2014Date of Patent: April 3, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jeffrey Allen Wagner, Thomas M Sabo, Ronald A Askeland, Gonzalo Gaston Llado, Alyssa Michelle Siegman, Lawrence H White, Alex Andrea Tallada, Brian J Keefe, Maria Magdalena Martinez Ferrandiz, Daniel Vincent Keane, Yi Hong Tor, Marian Dinares Argemi, Francisco Lopez Moral, Xavier Bruch, Chandrasekhar Nadimpalli
