In one example, a processor readable medium has instructions thereon that, when executed by a processor, cause a system to detect a change in electrical conduction of a liquid moving at an interface between two surfaces and determine a conductivity of the liquid based on the detected change in conduction.

Determining the conductivity of a liquid

Reducing print quality defects can include printing a pattern with an offset printing device having a binary ink developer roller, determining a variation for a hue shift of the printed pattern; and varying gain in a feedback loop of a servo motor coupled to the binary ink developer roller to reduce the variation.
