Publication number: 20220194098Abstract: In example implementations, a system is provided. The system includes at least one fluid ejection apparatus, a heater and an energy source. The at least one fluid ejection apparatus dispenses a de-contented fluid onto a substrate during conveyance of the substrate. The heater is arranged after the at least one fluid ejection apparatus along a substrate conveying path. The heater removes a liquid from the de-contented fluid on the substrate such that the particles of the de-contented fluid remain on the substrate. The energy source is arranged after the heater along the substrate conveying path. The energy source applies energy to the substrate during the conveyance of the substrate to heat the substrate to a temperature that is approximately a melting temperature of the substrate to fuse the particles on the substrate to the substrate.Type: ApplicationFiled: March 14, 2022Publication date: June 23, 2022Inventors: Yubai Bi, Guillermo Martinez Ariza

Publication number: 20190351683Abstract: A method comprises applying to a substrate a layer of substantially clear solvent-based printer fluid. The printer fluid comprises an ultraviolet light absorbing substance. The method comprises irradiating the applied layer of printer fluid with an ultraviolet light to heat the solvent and cause evaporation of the solvent. The waveband of the radiation is such that heating of the solvent is substantially due to heat transfer from the ultraviolet light absorbing substance in the printing fluid.Type: ApplicationFiled: March 5, 2019Publication date: November 21, 2019Applicant: HP SCITEX LTD.Inventors: Alex Veis, Yubai Bi
