    Abstract: An ink composition includes colorant, co-solvent system, acid (e.g., oleic, linoleic, undecanoic, dodecanoic, and/or tridecanoic acids), lithium, polymer as binder, and water. The co-solvent system is selected from i) from ˜9 to ˜25 wt % of sulfolane with no other co-solvent, ii) hydroxylated co-solvent, from ˜4 to ˜16 wt % of sulfolane, and at least 8 wt % of another non-hy-droxylated co-solvent; iii) hydroxylated co-solvent, from ˜7 to ˜16 wt % of sulfolane, and at least 3 wt % of the other non-hydroxylated co-solvent; and iv) a hydroxylated co-solvent and from ˜9 wt % to ˜16 wt % of sulfolane. When i) or ii) or iv) is used, at least 0.15 wt % acid and at least 200 ppm lithium are included; or when iii) is used, at least 0.25 wt % acid and at least 100 ppm lithium are included; or when iii) is used, at least 0.15 wt % acid and at least 150 ppm lithium are included.

    Abstract: A print head module for delivering ink to a print head comprising a module venting system comprising a one-time vent built into the interior of the print head module in which, when an amount of ink comes in contact with the one-time vent, air is prevented from passing through the one-time vent. A system for delivering ink to a print head comprising a print head, a external reservoir of ink, and a print head module comprising a one-time vent built into the interior of the print head module and fluidly coupling the print head to the external reservoir of ink, in which, when an amount of ink comes in contact with the one-time vent within the print head module, air is prevented from passing through the one-time vent.

    Abstract: A non-Newtonian photo-curable ink composition that comprises from about 0.1 wt % to about 10 wt % of metal oxide particles having an average particle size ranging from 1 to 50 nm; from about 0.05 wt % to about 10 Wt % of an inorganic salt; an organic solvent; a photo-initiator; and a polymerizable material; wherein the ink composition has a first dynamic viscosity ranging from 25 cps to 10,000 cps at a first state and a second dynamic viscosity ranging from 1 cps to 50 cps at a second state. Also described herein is a method for making such non-Newtonian photo-curable ink composition and a method for producing printed images using such non-Newtonian photo-curable ink composition.
