Abstract
In an implementation of a printing system, an electrophotographic imaging plate electrostatically attracts a first concentration of an ink having a particular color. A developer unit is biased with a developer voltage and the first concentration of the ink is transferred onto the electrophotographic imaging plate from the developer unit according to the developer voltage. The electrophotographic imaging plate then electrostatically attracts a second concentration of the ink. The developer unit is biased with an adjusted developer voltage and the second concentration of the ink is transferred onto the electrophotographic imaging plate from the developer unit according to the adjusted developer voltage.
