<p>An ink composition for roll printing is provided. The ink composition uses a solvent system having an evaporation rate (Vt) of at least 0.1 mg/cm2·min and an absorption rate (St) into a blanket of less than 3.412 mg/cm2·min. The use of the highly volatile solvent system can minimize swelling of the blanket without impairing the dispersibility of a pigment in the ink composition. Therefore, the uniformity of a pattern formed using the ink composition can be maintained and the formation of defects by the solvent system can be minimized.</p>
