ABSTRACT:
Disclosed are an inkjet ink and a method for printing on hydrophobic media such as offset coated media using the inkjet ink. Specifically disclosed is an inkjet containing a pigment, water and a surfactant which is characterized by also containing 40 to 75 weight % of a polar non-protic solvent with a molecular weight of 40 to 130 which has permeability to a hydrophobic surface such as the coating of an offset coated medium. Such an inkjet ink enables better printing on hydrophobic media such as offset coated media than the conventional inks.
