  • Publication number: 20070120927
    Abstract: 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.

  • Publication number: 20070103523
    Abstract: 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.

  • Publication number: 20060021546
    Abstract: Processes for preparing phase change inks comprising admixing (a) a phase change ink carrier; (b) a colorant of the formula or mixtures thereof, wherein M1, z, A1, R1, R2, R3, R4, R5, R6, R7, a, b, c, d, Y, Q, Q?, A1, and CA are as defined herein; and (c) a metal salt of the formula (M2v+)w(A2w?)v of which the metal portion M2 is either a metal ion having positive charge +v, a metal-containing moiety, or a mixture thereof, and A2 is an anion having negative charge ?w, wherein M1 and M2 can be the same as or different from each other, wherein A1 and A2 can be the same as or different from each other, said admixing occurring at a temperature at which the ink carrier is a liquid.
