An ink additive, specifically 1,4 butanediol, is added to color inks. When 1,4-butanediol is added to the inks, curl and cockle of the printed substrate is significantly reduced without reducing surface tension of the ink. Surface tension of process color inks for some printers are kept high to eliminate color-to-color bleed and to reduce showthrough on the opposite side of the paper. The 1,4-butanediol additive provides an anti-cockling advantage without adversely affecting the surface tension of the ink.
