Disclosed is a phase change ink composition comprising an ink carrier and a colorant, said ink being suitable for use in an indirect printing process wherein the ink is jetted from a printhead onto a heated intermediate transfer member and subsequently transferred from the intermediate transfer member to a final recording substrate, wherein: (a) the ink can be jetted from the printhead onto the intermediate transfer member when the ink is maintained at a temperature of about 125° C. or lower; (b) the ink can be jetted without purging from a printer maintained at a standby temperature of about 100° C. or lower; and (c) the ink has a cohesive failure temperature of at least about 56° C.
摘要:
A method of operating a printer turns off a support structure heater when the printer enters standby mode. The print head is then moved away from an intermediate transfer surface supported by a support structure. Heat settings used to heat a print head are then varied to heat the print head and the support structure. Another method of operating a printer turns off a support structure heater when the printer enters standby mode and holds a print head adjacent to an intermediate transfer surface while the printer is in standby mode.
