A method, at least partially implemented by means of processor-executable instructions, for exchanging colors within a color station of a printing press is disclosed. In one implementation of the method, a cleaning tank is operated within the color station, thereby cleaning the color station. Additionally, a new color of ink is built within the cleaned color station.

In one embodiment, a method for controlling an ink supply system includes operating a pump of the ink supply system in a forward direction to supply ink from an ink reservoir to an ink tank, and subsequent to operating the pump in the forward direction, reversing the pump and operating the pump in a reverse direction to prevent or reduce formation of clogs within the ink supply system.

A member for controlling foam in a material reservoir includes a body, a concave space in the body, and wings extending from the body in the concave space. A method of controlling foam in an ink reservoir of a printing system includes rotating a foam control member above ink in the reservoir to dissipate accumulated foam, where the member includes a concave space open toward the ink and wings extending in the concave space.
