Device and method for printing different images

FIELD: printing industry.

SUBSTANCE: device for printing different images on the printable material comprises of: the first cylinder having a plurality of printing forms, having the first ink area which receives ink from a paint source; and the second cylinder, having the second ink area and the second non-ink area. The first and second cylinders operate in such a way that the second ink area the second cylinder receive ink out of the first ink area of the first cylinder, and the second non-ink area of the second cylinder is at least partially combined with the first ink area of the first cylinder. In addition, the second non-ink area is designed to prevent the ink from moving from the first ink area to the second non-ink area. The second cylinder contains a variety of transfer forms and two or more transfer forms of the second cylinder have different second non-ink areas and different ink areas for printing images, with some different content and some general content. The second non-ink area of the transfer forms is separated by grooves from the second ink area of the transfer form and images, printed using at least two transfer forms, have different content. Printed image is defined by the parts of the first ink area and the second ink area, which are combined so that different content in images is background (negative) printing, formed by the non-ink area of the transfer forms.

EFFECT: increase in the economic efficiency of production of a smaller number of products having printed content of an individual character.

SUBSTANCE: method and device (50) to apply printing ink are designed to create an image with printing ink on a surface of a type cylinder (15b) of a printing machine, which has at least partially a 2D printing ink gradient passing in axial direction and in circumferential direction on the surface of the type cylinder (15b). At least the first and second stencil cylinders (20, 25) are installed one behind the other along the way of printing ink application by a dyeing machine (20, 25, 30, 31, 32, 33, 34, 36, 37) for application of printing ink onto the type cylinder (15b) to ensure distribution of printing ink in axial and circumferential directions, besides, there are facilities to ensure periodic oscillating displacement of the first and second stencil cylinders (20, 25) in axial and circumferential directions.

EFFECT: increasing distance, within the limits of which printing ink may be distributed without increasing amplitude of stencil cylinder oscillation and increasing evenness of printing ink distribution in axial and circumferential directions.

FIELD: printing industry.

SUBSTANCE: invention relates to printing machine. Printing machine comprises printing unit that prints on sheet, processing unit that processes sheet, the first driving unit for printing unit driving, the second driving unit for processing unit driving and control unit for control of the first and second driving units to synchronise driving units of printing unit and processing unit to each other.

EFFECT: invention eliminates phase variances between printing machine and processing device and eliminates defects in printing.
