A thermal ink jet ink composition includes one or more volatile organic solvents, wherein the one or more volatile organic solvents comprise a solvent selected from C-Calcohols, C-Cketones, C-Cesters, C-Cethers, and mixtures thereof. The one or more volatile organic solvents are present in an amount at least 60% by weight of the ink composition. The ink composition includes one or more binder resins present in an amount from 1% to 10% by weight of the ink composition, and one or more dyes. If water is present, it is present in amount less than 5% by weight of the ink composition. The ink composition includes less than 2% by weight of any humectant and/or wetting agent with a relative evaporation rate less than 0.3. The ink composition is suitable for use in a thermal ink jet printer.

High adhesion TIJ ink

A thermal ink jet ink composition includes at least 50% by weight volatile organic solvent selected from C-Calcohols, C-Cketones, C-Cesters, C-Cethers, and mixtures thereof; a colorant; a humectant present in an amount from about 1% to about 30% by weight; from 0.3% to 8% by weight of a binder resin; and not more than 5% by weight water; wherein the ink composition is compatible with components of a thermal ink jet printer.

Thermal ink jet ink composition

A method of printing a security code on an article includes applying droplets of an ink composition with an ink jet printer to a surface of an article to print an encrypted code. The ink composition includes an organic solvent, a binder resin, and a luminescent dye.

Method of printing security code

An ink jet ink composition includes an organic solvent in an amount between 60% and 95% by weight of the ink composition, a binder resin, a stabilizing agent, which may be provided by the binder resin, and a pH sensitive dye. An image formed by the ink composition changes from a first color to a second color when exposed to water, wherein the first color is different than the second color.

Color changing inkjet ink composition

A method of printing on a hygienic article includes applying droplets of an ink composition with an ink jet printer to a surface of a hygienic article to form a desired image. The ink composition includes an organic solvent, a water-soluble binder resin including hydroxypropylcellulose, and a water-soluble dye. The image acts as a wetness indicator by dissolving in an aqueous fluid.

Wetness indicating ink compositions

A method for printing images on a substrate with an ink jet printer includes providing a liquid ink composition. The liquid ink composition includes an organic solvent, a binder, and a colorant. Droplets of the ink jet ink composition are directed to a plastic film substrate. The droplets are allowed to dry, thereby printing a durable graphic image on the substrate.

Method of printing on a film substrate

A printing method includes providing a print head. The print head includes a valve and at least one orifice. Fluid is ejected from the orifice in a generally continuous stream. The fluid includes a conductive material. The fluid is deposited in a pattern on a substrate to form an electrically conductive deposit. At least a portion of the pattern includes a generally straight line.

Stream printing method

A method of cleaning a print head assembly comprising a print head and a cover includes removing the cover from the print head assembly. A cleaning unit includes a fluid chamber, a fluid intake port, and a fluid exit port. The cleaning unit is attached to the print head such that the fluid chamber surrounds a portion of the print head. A solvent is introduced into the fluid chamber to contact the print head. The solvent is allowed to clean the print head. The solvent is removed from the chamber.

Printer cleaning method

An ink jet ink composition includes an organic solvent, a binder, and a colorant. The colorant is selected from at least a first pigment and a second pigment. If the ink composition comprises carbon black, the carbon black is present in an amount less than 30% by weight of the total pigment content.

Pigmented ink jet ink composition

Disclosed is an ink composition suitable for ink jet printing comprising a luminescent compound, a solvent, and an energy active compound, and optionally a non-luminescent colorant. The energy active compound, when exposed to energy, generates one or more active species that can react with the luminescent compound to alter one or more of the characteristics of the luminescent compound. The luminescent compound can be colored or colorless. Also disclosed is a method for marking substrates comprising providing a mark comprising a luminescent compound and an energy active compound. Further disclosed is a jet ink composition suitable for printing on substrates authentication or security marks which can be rendered unreadable. The luminescence of the mark is quenched and the visible color is changed when irradiated with a light.
