Abstract: A process and apparatus for gravure printing of an image using an erasable and reusable gravure form including a gravure blank form having a base screen which is designed for accommodating a maximum amount of ink to be transferred. The depressions of the base screen of the gravure blank form are uniformly filled with a liquefiable substance using an applicator device and material is then removed from the depressions in conformity with the intended image using thermal energy applied by an image-point transfer device. The printing form is then linked using an inking system and, finally, is regenerated after the printing process to produce a gravure blank form, wherein the depressions of the base screen are again filled in a uniform manner.

Abstract: A process for gravure by means of an erasable and reusable gravure form proceeds from a gravure blank form with a base screen which is designed at least for the maximum amount of ink to be transferred. The depressions of the base screen of the gravure blank form are uniformly filled with a liquefiable substance by means of an applicator device and material is then removed from the depressions in conformity to the intended image by means of thermal energy applied by an image-point transfer device. The printing form is then inked by means of an inking system and, finally, is regenerated after the printing process to produce a gravure blank form, wherein the depressions of the base screen are filled again in a uniform manner.

Abstract: A device for filling depressions in a cylinder of a printing machine with a fluid, e.g., an ink, which permits a quick change to a different fluid, includes at least two doctor blade devices arranged on the cylinder which doctor blade devices can be selectively moved individually into effective connection with the cylinder.

Abstract: Starting from a blank gravure form, a filling step and a subsequent imaging step are carried out to produce a printing form. In the filling step, depressions are evenly filled with a UV printing ink by an application device, and the UV printing ink is then solidified by a UV drier. In the imaging step, solidified UV printing ink is removed from the depressions in accordance with the image by thermal ablation. The gravure form screened in accordance with the image is then inked with UV printing ink by an inking system. For reuse, the gravure form undergoes an erasure step that uses UV printing ink.

Abstract: A web-fed rotary printing machine having a plurality of directly adjacent printing units. Each of the printing units has only one side wall, in which the printing group cylinders are float mounted. The printing units are arranged in-line with no working space between them.

Abstract: Disclosed is an apparatus to insure the most even linear force possible in the contact zone across the breadth of cylinder bodies of apparatus positioned next to each other. The printing group cylinders are positioned and maintained via the disclosed arrangement in such a way that adjacent cylinder bodies have an approximately parallel orientation.

Abstract: In a compact drive for a float-mounted cylinder of a rotary printing machine, the spindle carrying the cylinder is housed together with a motor in a carrier tube mounted in the side wall.
