Abstract
The present invention is drawn to systems, methods, and ink-jet ink compositions that include an aqueous liquid vehicle including at least three co-solvents selected from the group consisting of tetraethylene glycol, glycerol, diglycerol, 1,5-pentanediol, 2-pyrrolidone, ethylhydroxy-propanediol. In particular, the composition includes the at least three co-solvents being present in combination in the ink-jet ink at from 10 wt % to 25 wt %, and further includes a dye.
Claims41
An ink-jet ink composition, comprising:
- a) an aqueous liquid vehicle including at least three co-solvents selected from the group consisting of tetraethylene glycol, glycerol, diglycerol, 1,5-pentanediol, 2-pyrrolidone, ethylhydroxy-propanediol, said at least three co-solvents being present in combination in the ink-jet ink at from 10 wt % to 25 wt %;
- and
- b) a dye.
A system for printing an ink-jet ink, comprising:
- a) an ink supply cartridge containing an ink-jet ink, said ink-jet ink including;
- i) an aqueous liquid vehicle including at least three co-solvents selected from the group consisting of tetraethylene glycol, glycerol, diglycerol, 1,5-pentanediol, 2-pyrrolidone, ethylhydroxy-propanediol, said at least three co-solvents being present in combination in the ink-jet ink at from 10 wt % to 25 wt %;
- ii) a dye;
- b) an off-axis printer including ink delivery system tubes and a printhead, said ink delivery tubes configured for transferring the ink-jet ink from the ink supply cartridge to the printhead.
A method of printing, comprising jetting an ink-jet ink from an off-axis printer, said off-axis printer including:
- a) an ink-supply cartridge,
- b) ink delivery system tubes, and
- c) a printhead,
- said ink delivery tubes configured for transferring the ink-jet ink from the ink supply cartridge to the printhead, said ink-jet ink including:
- a) an aqueous liquid vehicle including at least three co-solvents selected from the group consisting of tetraethylene glycol, glycerol, diglycerol, 1,5-pentanediol, 2-pyrrolidone, ethylhydroxy-propanediol, said at least three co-solvents being present in combination in the ink-jet ink at from 10 wt % to 25 wt %, and
- b) a dye.
