International Classification:

C09D 11/40
C09D 11/107

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.
