1. 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
at least one photo initiator,
wherein the metallic ink composition has a first viscosity ranging from 150,000 to 1,000,000 millipascal seconds (mPa·s) at 0.1 rad/s at 25° C. and a second viscosity ranging from and 85,600 mPa·s at 100 rad/s at 35° C.,
wherein the metallic ink composition further comprises an additional colorant, and wherein the additional colorant is an organic white pigment in an amount ranging from 0 to 5% by weight.
