A printing unit (1) of a rotary printing press for using various ink types is provided. The printing unit includes an inking mechanism (45), a print cylinder (3), and a blanket cylinder (2). The inking mechanism (45) and the cylinders (2, 3) are mounted in side walls of the printing unit (1). A housing (14) at least partially surrounds the inking mechanism (45) and the cylinders (2, 3) to maintain a surrounding atmosphere within an at least semi-enclosed area (100) of the printing unit (1). A chemical agent is selectively added to the atmosphere in the semi-enclosed area (100) to reduce the rate of evaporation of a substance in the ink. |
