摘要： 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.

摘要： In a method and printing apparatus to print a continuous printing substrate, a liquid film with toner and courier fluid is transported to a charge image carrier to develop charge images into toner images. Transport pairs are used comprising rotating transport members in the transport of the liquid film to the charge image carrier and from the charge image carrier to the printing substrate. Given a changing print speed of the printing apparatus at least one of the respective transport pairs is adjusted to provide a respective separation of the transport members from one another so that a substantially same quantity of the liquid film is always conveyed by the respective transport pair.

摘要： In an electrographic printing apparatus, a charge image carrier has charge images generated thereon of images to be printed. A developer station develops the charge images into an image film with carrier fluid and embedded toner images. A transfer unit receives the image film from the charge image carrier and transfers the image film onto a printing substrate. A fixing station fixes the image film on the printing substrate. A carrier fluid recovery device is arranged between the fixing station and the transfer unit, and recovers carrier fluid from carrier fluid vapor occurring in the fixing station and supplies the recovered carrier fluid to the transfer unit.

摘要： In a method to optimize transfer of a developer fluid on a printing substrate in an electrophoretic printing apparatus, a developer fluid containing at least carrier fluid and toner particles is used, the toner particles having sizes that are greater than diameters of capillaries in a surface of the printing substrate. The additive particles are added to the developer fluid before the transfer, sizes of the additive particles being selected such that the sizes are smaller at least in part in comparison to the diameters of the capillaries in the surface of the printing substrate.

摘要： Amphiphilic toner which has both hydrophilic groups and lipophilic groups in the molecule, use thereof for an electrophoretic printing process, and method for an electrophoretic printing process using it. The toner is first dispersed in a non-polar carrier liquid, the toner-containing carrier liquid being transported from a charge image carrier by means of a transfer roller to a point of transfer and from there transferred to a substrate. A polar liquid is added before transfer of the toner to the substrate.

A scoop element applies carrier fluid to the transfer element. A friction element is provided after the scoop element adjacent to the transfer element at such a distance from the transfer element that a gap between the transfer element and the friction element is substantially completely filled with the carrier fluid, the friction element and the transfer element rotating with different speeds. Residual toner remaining on the transfer element after the transfer printing is loosened by friction forces.

摘要： Printed images exhibiting a color medium are applied to the printing substrate by a printing device, the printing substrate having been provided beforehand with a viscous fluid film by an application unit arranged in front of the printing device. The color medium of the printed images migrates to a surface of the viscous fluid film and adheres there. After the drying of the fluid film the printed images are firmly fixed on the printing substrate.
