    Abstract: An ink composition, including an ink base and a wax emulsion. A viscosity of the ink composition is between 80 Pa·s and 400 Pa·s at 100 rad/s and 25° C., and a tack of the ink composition is between 32 g-m and 45 g-m at 60 seconds. The total wax content of the ink composition is between 1% and 5% by weight, based on a total weight of the ink composition, and the total water content of the ink composition is between 1% and 15% by weight, based on the total weight of the ink composition.
