Claim:
1. An ink composition for variable data offset printing or an ink jet printing process that uses an intermediate substrate, comprising: nano-particles, wherein each nano-particle is a polymer or a polymer blend of polymers, wherein the polymer or the polymers of the polymer blend are water dispersible at temperatures less than 100 degrees Celsius, wherein the total solids content of the ink composition is an amount in a range of about 25% or greater by total weight of the ink composition, wherein the polymer or the polymer blend comprises a sulfonated polyester, and wherein the sulfonated polyester is copoly(1,2-propylene-dipropylene-terephthalate)-copoly(1,2-propylene-dipropylene-5-sodiosulfoisophthalate).
