    The invention relates to the printing industry, in particular to the inking apparatus of a rotary offset machine.
    The aim of the invention is to improve the quality of printing.
    FIG. Figure 1 shows a schematic diagram of an inking apparatus in which the sprayer device contains a chamber squeegee; in fig. 2 - the same, but the ink transfer device contains a ductor roller; in fig. 3 - cells of the spray cylinder, transverse section.
    The inking machine of the rotary offset machine contains a paint transfer device installed on the base, a front-paint cylinder 1 that interacts with it, a plate cylinder 2 with an offset form, at least one knurling roller 3, which interacts with the paint-transfer 1 and plate
    2 cylinders, a humidifying device 4 and a pneumatic air blower 5 mounted on an axis parallel to the axis of the paint-transfer cylinder 1. The spray-paint cylinder 1 is rasterized and provided with heating means (not shown), while the forme cylinder 2 is equipped with means for cooling it (not shown), and the air nozzles are located at the working surface of the paint-transfer cylinder 1.
    The raster of the paint cylinder cylinder 1 is formed by bridges 6 and cells, with the end surface 8 of the bridges 6 made of a hydrophilic material, and the surface of 9 cells 7 is of a short oleophilic material.
    The device works as follows.

    means of the paint apparatus roll paint. By means of a humidifier 4 of a known construction, the offset form 10 is smoothed. In one embodiment (FIG. 1), the paint transfer device comprises a chamber doctor blade 11, which serves to supply paint to a rasterized, hard paint transfer cylinder 1 (such as anilox). By means of two rubber-covered knurling rollers 3, the usual offset printing ink is transferred from the chrome-plated rasterized color of the conveying cylinder 1 to the offset form 40. The rasterized ink-transmitting cylinder 1 is designed to be heated to approximately 40-60 seconds. As a heating device, you can use any known device. The heating device may contain either a thermostat or it may be connected to a separate thermostat. The offset cylinder supplied with the form cylinder 3 is adapted to be cooled to a temperature between 20 and 25 ° C. As a cooling device (not shown), you can use any known device. The cooling device can contain either a thermostat or can be connected to a separate temperature controller.
    In addition, a series of pneumatic air heater 5 can be installed parallel to the rasterized paint-transfer cylinder 1, supplying a stream of dried air to the rotating paint-transfer cylinder 1. By heating the paint-transmitting cylinder 1, heat transfer is also achieved to the knurling rollers 3, as a result of which heated. Due to the heated rollers 3 and, above all, the heated ink-transfer cylinder 1, evaporation of the excess moistening liquid is achieved on the way to the printing ink supply device, chamber squeegee 11 (Fig. T) or ink reservoir 12 (Fig. 2). cylinder 1 with dry air, the evaporation of the moistening liquid on and in the ink itself on the way back to the device 11 or 12 dp of ink supply is enhanced.
    FIG. 2 chamber squeegee 11 is replaced with a colorful reservoir 12 and a squeegee 13, installed with the possibility
    four
    interaction with the spray cylinder. 1. The ductor roller 14 transfers the offset printing ink from the ink reservoir 12 to the surface of the rasterized paint transfer roller 1.
    Due to the described measures, it is achieved that the moistening liquid does not penetrate completely (or only in a small amount) into the device 11 or 12 for the supply of printing ink, and thus the offset printing ink is not emulsified with water.
    As seen in FIG. 3, the rasterized ink-transfer cylinder 1 has cells 7 and jumpers 6, with the end surfaces 8 of jumpers 6 cells 7 through which the squeegee 13 or chamber squeegee 11 constantly passes, are chrome-plated, i.e. hydrophilic, and one surface of 9 cells 7 is covered with oleophilic or at least less hydrophilic coating, for example, nitrated chromium.
