Zusammenfassung:The present disclosure is directed to a metallic ink composition for use in digital offset printing, comprising: metallic effect pigment particles, wherein an average equivalent sphere diameter of at least about 90% of the metallic effect pigment particles ranges from greater than 1 micrometer (μm) to 150 μm; at least one dispersant; at least one curable oligomer; and a photo initiator, wherein the metallic ink composition has a viscosity ranging from 150,000 to 1,000,000 millipascal seconds (mPa·s) at 0.1 rad/s at 25° C. Also provided is a method of digital offset printing using the metallic ink composition of the present disclosure.
