Abstract: An inkjet ink for an offset coated medium includes: water; a colorant; a binder that is a polyurethane-based dispersion; a co-solvent; and two or more surfactants. A first surfactant has a first hydrophilic lipophilic balance (HLB) value either within a water dispersible range or within a hydrophobic range and a second surfactant has a second HLB value within a hydrophobic range. The combination of the first surfactant and the second surfactant is to adjust a surface tension of the inkjet ink to a value lower than a surface tension of the offset coated medium on which the inkjet ink is to be printed.

Abstract: The present disclosure sets forth a fluid set and a method of wet-on-wet printing. The fluid set can comprise an analog pretreatment fluid including water, latex, and a salt; and a first and second inkjet ink each comprising water, pigment, a solvent system, and a surfactant system. The analog pretreatment fluid can be prepared to have a surface tension from 32 dynes/cm to 40 dynes/cm. The first inkjet ink can have a surface tension ranging from 2 dynes/cm greater than the surface tension of the analog fixer fluid to 6 dynes/cm less than the surface tension of the analog fixer fluid. Likewise, the second inkjet ink can have a surface tension ranging from 2 dynes/cm greater than the surface tension of the analog fixer fluid to 6 dynes/cm less than the surface tension of the analog fixer fluid.
