Abstract: A printing system can include an energizer, a condition group, a print group, a sensor, and a controller. The energizer can be configured to treat a surface of a recording medium to increase an energy of the surface. The conditioning group can be configured to provide a coating substance on the surface having been treated by the energizer to provide a pre-treated recording medium having a coated surface. The print group can be configured to print a toner-based print image onto the coated surface of the pre-treated recording medium using electrophoresis. The sensor can be configured to detect resistance data indicative of a resistance of the pre-treated recording medium orthogonal to the coated surface of the pre-treated recording medium. The controller can be configured to control the energizer to adapt a dimension of the increase of the energy of the surface of the recording medium based the resistance data.

Abstract: A print group for a digital printer can include a transfer station and a wetting system. The transfer station can be configured to transfer a toner image onto a first side of a recording medium at a transfer point in response to an electrical field, the transfer station being configured to apply the electrical field between a transfer electrode on the first side of the recording medium and a counter-electrode on a second side of the recording medium, wherein the recording medium is directed between the transfer electrode and the counter-electrode. The wetting system can be configure to apply a conductive fluid onto a surface of the second side of the recording medium at the transfer point, the conductive fluid at least partially forming a conductive connecting layer between the surface of the second side of the recording medium and a surface of the counter-electrode at the transfer point.

Abstract: In a method or system to control a temperature of a substrate to be printed to and which exhibits said temperature during a traversal of a printing system, specifically selecting or controlling a fluid temperature of a liquid fluid to be applied onto the substrate to specifically influence the substrate temperature, the fluid being applied onto the substrate before the substrate is printed to. At least one of the fluid temperature and a quantity of the fluid applied onto the substrate per time unit at least depending on at least one of a first measurement value for a temperature of the substrate before the application of the fluid and a second measurement value for a surface temperature of the substrate after the application of the fluid.

Abstract: Printing systems and methods for conditioning a recording medium are described. For example, to condition the recording medium, a property of a coating substance to be applied to the recording medium, such as the composition of the coating substance can be adjusted. Further, the quantity of the coating substance to be applied to the recording medium can be adjusted. The quality of a printed image created by the printing system can be improved by adjusting the property and/or the quantity of the coating substance.
