ABSTRACT:
A gravure ink composition and method of using the same for printing by the gravure process are disclosed. The composition comprises a pigment, a vehicle composed basically of a resin and solvent, and a small amount, e.g., 0.0002 to 1 wt. %, of an antioxidant. The antioxidant serves as a means for reducing the tendency of gravure ink formulations to streak during the printing process, particularly during high-speed printing operations. A preferred gravure ink formulation contains a small amount of an antioxidant such as 2,6-di-tert-butyl-4-methylphenol or 4,4'-bis(1,1,3,3-tetramethylbutylphenyl)amine.
