Printing machine for printing securities with orlov's office printing equipment, and also way to change printed form and start production

FIELD: printing industry.

SUBSTANCE: invention relates to a printing machine for printing securities with an Orlov offset printing machine including a plurality of template cylinders that are capable of being stained with a colouring apparatus imparted to them, interacting with a plurality of template cylinders, an air cylinder, an Orlov form cylinder cooperating with a pressure cylinder With a form cylinder, a transfer cylinder and a backpressure cylinder forming a printing location with a transfer cylinder. At least one transfer cylinder interacting with the Orlov form cylinder at the position of the feeder is covered by the first section of the printing apparatus and has a support in or on the first part of the frame. The pick-up cylinder is covered by a second portion of the printing apparatus and has a support in the second part of the frame, different from the first part of the frame. The first and second part of the frame can be arbitrarily brought into the first position relative to each other forming the operating position and to the second position relative to each other forming a maintenance position. In the maintenance position, between the first and second portions of the printing apparatus and/or between the first and second parts of the frame, a space is formed that gives immediate access, at least to the pressure-collecting cylinder, to the Orlov form cylinder and to the transfer cylinder interacting with the form cylinder. In addition, the invention relates to a method for replacing a printing plate and starting production.

FIELD: polygraphy, in particular, printing machines, possible use for applying protective pattern during printing of important documents, in particular, securities of various purposes.

SUBSTANCE: printing machine contains painting system, including paint box with paint separators, painting cylinders comprising rubber cylinders made with circular grooves of alternating width, and plastic cylinders, connected to mechanism for their reciprocating axial movement, and master cylinder, interacting with aforementioned painting cylinders and offset cylinder, which contacts sheets being printed via the printing cylinder. Five rubber cylinders are made with circular grooves, width of circular grooves in which is made in accordance with relationship where N - cylinder number, in order of appearance starting from paint box; Y(N) - width of circular groove on cylinder number N; Ao - width of paint separator; B - amplitude of axial movement of plastic cylinders. Usage of printing machine ensures minimized flow of paint set, and also even and precise distribution of paints during transportation from paint box onto the surface of master cylinder. Also, due to reduction of amount of used paint, cost of produced printing product is reduced. Multicolor image, produced as a result of printing, uses iris effect, making it possible to create securities with high degree of protection due to identity of characteristics of programmed image and resulting image.

EFFECT: increased efficiency.

FIELD: printing form for printing of, in particular, securities and documents, and a printing method.

SUBSTANCE: printing form contains, at least, two functional layers 1 and 2, first one of which is made with through printing elements 3 and 4 for transferring painted image directly onto carrier material 5. Printing form has means 8 for tearing paint layer and redistributing paint in printing elements between layers, which means may be made in form of a mesh or honeycombed structure between layers 1 and 2. In accordance to invention, printing method includes transferring form pattern onto carrier material by means of described printing form, while during printing pressure is created in printing zone, value of which exceeds the yield point value of the carrier material.

EFFECT: possible creation of imprints, analogical to metallographic printing imprints, with more complicated structure and increased degree of protection from forgery; improved quality of imprints due to decreased probability of spraying of paint across space sections of form during printing, and also due to fine-grain structure of imprint surface with high productivity and possible use of broad assortment of painting materials.
