Abstract: A printing press dryer having an excimer radiant heater adapted for high energy output and compact mounting within the printing press. The heater includes a housing (1) within which a plurality of radiant tubes (2,3) are arranged in parallel relation to each other, and the radiant tubes (2,2) each have a respective adjacent reflector section (4,5) for directing a predetermined radiation distribution on passing printed sheet material.
Abstract: A method and apparatus for coating printed products, wherein the products are initially printed in at least one printing process and are provided with a layer that covers the printing ink on the printed product immediately thereafter in at least one coating process. According to the invention, a corona treatment device is arranged between the final printing station and a device for coating the printing products for subjecting the printing ink on the printing product to a corona treatment immediately after the printing process such that UV varnish can be directly applied onto the printing inks without the requirement of additional printing processes.

Abstract: The invention pertains to a drying apparatus within a sheet-fed printing machine, in particular, a sheet-fed offset printing machine, with a device for acting upon the moving sheets with air and/or heat. The present invention is based on the objective of expanding a drying apparatus of this type in such a way that the drying effect is improved. According to the invention, this is achieved due to the fact that the apparatus contains an electrode (E) and a corresponding counter-electrode, wherein the electrode is connected to a high-voltage source (HV) and a high voltage is applied to the electrode by the high-voltage source in dependence on the operation of the sheet-fed printing machine and/or the length of the sheets (B).
