Abstract
Abstract An ink jet ink composition comprises a liquid vehicle, a single dye component, a surfactant and a glycol. The dye is water soluble and selected from the group consisting of Direct Dyes, Acid Dyes and Food Dyes, and preferably from the group consisting of Direct Yellow 86, Acid Red 249, Acid Red 92 and Direct Blue 199. Concentration of the dye is preferably in the range of 1% to 2% by weight. Using the ink composition of the present invention, images are generated by a continuous stream digital color press ink jet printing apparatus. In a preferred embodiment, to optimize runnability and jet straightness, the digital color press employs a gold orifice plate having an orifice diameter in the range of 0.7 to 0.8 mil.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
63 words
A primary color ink jet ink composition for use with a digital color press, the primary color ink jet ink composition comprising a liquid vehicle, a single dye component, the dye component being water soluble and selected from the group consisting of Direct Yellow 86, Acid Red 249, Acid Red 92 and Direct Blue 199, an ethoxylated acetylenic diol surfactant and ethylene glycol.
Claim 2
Dependent Claim
63 words
A primary color ink jet ink composition for use with a digital color press, the primary color ink jet ink composition comprising a liquid vehicle, a single dye component, the dye component being water soluble and selected from the group consisting of Direct Yellow 86, Acid Red 249, Acid Red 92 and Direct Blue 199, an ethoxylated acetylenic diol surfactant and ethylene glycol.
Claim 3
Dependent Claim
30 words
An ink jet ink composition as claimed in claim 1 wherein the dye is water soluble and selected from the group consisting of Direct Dyes, Acid Dyes and Food Dyes.
Claim 4
Dependent Claim
25 words
An ink jet ink composition as claimed in claim 1 wherein concentration of the dye is in the range of 1% to 2% by weight.
Claim 5
Dependent Claim
30 words
An ink jet composition as claimed in claim 1 wherein the liquid vehicle is selected from the group consisting of a wetting agent, a biocide, deionized water, and mixtures thereof.
Claim 6
Dependent Claim
33 words
An ink jet composition as claimed in claim 4 wherein the liquid vehicle is selected from the group consisting of a wetting agent, a biocide, deionized water, a corrosion inhibitor, and mixtures thereof.
Claim 7
Dependent Claim
14 words
An ink jet composition as claimed in claim 1 further comprising a pH modifier.
Claim 8
Dependent Claim
42 words
A process for generating images which comprises incorporating into an ink jet printing apparatus the ink composition of claim 1 and forming images by causing the ink to be expelled in droplets onto a substrate, thereby generating an image on the substrate.
Claim 9
Dependent Claim
20 words
A process as claimed in claim 7 wherein the image is generated by a continuous stream ink jet printing process.
Claim 10
Dependent Claim
25 words
A process as claimed in claim 8 wherein the image is generated by a continuous stream ink jet printing process having a gold orifice plate.
Claim 11
Dependent Claim
24 words
A process as claimed in claim 9 wherein the gold orifice plate has an orifice diameter in the range of 0.7 to 0.8 mil.
