METHOD OF TOOL CLICHE PRODUCING Russian patent published in 2017 - IPC B41C1/00 

FIELD: printing industry.

SUBSTANCE: method of lithographic printing plates producing including the manufacture of lithographic printing plate with the image subject to a tooling, and making of a form for tooling, characterized in that the form for tooling is formed directly on the printing cylinder of the printing machine, which is first run in a mode without sheets supply, the offset form is moisturized during the machine cylinder rotation with a wetting mechanism, during each revolution of the offset printing machine cylinders UV glue preloaded in the inking unit is layerwise applied onto the printing cylinder, during the subsequent rotation of the cylinder, each of microlayers applied on the printing cylinder in layers, is fixed with ultraviolet lamps, under the influence of which the matter polymerization is carried out and a thin form polymer layer is formed on the printing cylinder, in what connection the process is carried out till the polymerized matter haunched members at least 1 mm high are formed, then the inking and wetting mechanisms, ultraviolet lamp are switched off, after which the printing machine is set in sheet supply mode, and an impressed image is formed on a sheet passing between the printing and offset cylinders.

EFFECT: improving the quality of the image subject to a tooling due to the preparation of a form with a greater detailing by forming it directly on the printing cylinder of the printing machine, reducing circulation production time.
