なるか又は乾燥する欠点を有する。Prior Art German Patent No. 2,948,486 discloses an inking unit of a rotary offset printing press which already has a device for removing human blood from a layer of ink and dampening water on the rollers of the inking unit and dampening unit. and dampening water devices are known. With such devices it is possible, for example, to avoid or eliminate so-called ink-water emulsion beds on the inking or dampening devices or the rollers used therein. For the same purpose, it is also known from DE 23 28 953 to equip the rollers with brushes for removing the ink-water layer. Such brushes often have the disadvantage that they absorb a lot of different ink and the ink clumps or the ink forms a hard crust or dries in the bristles of the brush.

3 is arranged, which is provided with an ink layer in the conventional manner from an ink reservoir, not shown, optionally via further rollers. Several nozzles 5 and 6 are arranged parallel to the roller 2 of the inking device.
is fixed. The nozzle mounting device 4 is supported or fixed on the side wall 1 in the same way as the rollers 2.3 of the inking device. Advantageously, the mounting of the nozzle is such that the fixture 4 is fixed to the side wall 1, and the nozzle mounting is formed in such a way that the arrangement of the fixture 4 relative to the other rollers is possible; A differentiated portion of the roller, indicated at 8, can be treated with the method of the invention. That is, nozzles 4, 5 coat certain parts of the roller with a powder or spray (for example a face) or other aerosol or suspension. Such spray particles provide a natural separation of the ink layer on the rows 22 of the inking device, so that the risk of liquid flattening can be avoided by an excessive amount of dampening water.

調整する。In the distributor 18, the substance to be sprayed, for example a powder, is fed through an injector 14 and a dosing part 15 from a storage container 16, which can be filled by means of a connecting sleeve 1T. Condenser 11 handles the powder to be sprayed.
This condenser can be used to adjust the injector by means of a magnetic valve 12. The eccentric 13 adjusts the magnetic valve 12 in relation to the zone of the roller to be coated with powder on the respective associated roller parts 7, 8, etc.

A certain roughness of the ink layer present on top of the ink layer 2 is obtained, which results in activation of the separation or avoidance of flattening of the liquid. This also ensures that the ink is transferred from the rollers again at the appropriate rate to the area where the ink is pre-filled and is again fully filled. Suitable spray agents other than the above-mentioned substances are all substances which increase the affinity of the water-enriched ink for the next roller.
