Abstract
In a method or apparatus to optimize transfer of a developer fluid having toner embedded in a carrier fluid in an electrophoretic printing apparatus, charge images of print images are generated on an intermediate image carrier. The print images are inked into toner images by means of a developer station with the developer fluid. The toner images are transfer printed onto a printing substrate in a transfer printing zone by a transfer unit. The toner embedded in the carrier fluid is thus transported from the developer station to the intermediate image carrier in a first transport path segment and from the transfer unit to the printing substrate in a second transport path segment. A temperature acting on the carrier fluid in the first transport path segment is above a melting point of the carrier fluid, and a temperature acting on the carrier fluid in the second transport path segment is below the melting point of the carrier fluid.
