The invention relates to a method of manufacturing securities and metallographic printed form for producing securities.

A known method of manufacturing securities, is the impact of metallographic printing form on a carrier, the transfer ink layer and the subsequent formation of a latent image to protect the paper from a fake.

Here described and metallographic printing form for the manufacture of securities on the working surface of which is recessed to provide educational opportunities on the media hidden colorful images to protect the paper from forgery (US patent No. 4033059, 05.07.1977).

A disadvantage of the known technical solutions is a low security securities from a fake.

The technical result of the invention is to improve reliability of the protection securities from a fake.

The way this is achieved by the fact that in it the image is performed in the form of a set of projections of the paint layer and the hollows between them, the width of the protrusions of the paint layer is more than 0.5 mm, and the paint layer of the projections performed with continuously changing optical density to enable a smooth or stepped transition from the saturated layer of paint to the midtones.

In the method of continuously changing the optical density of the paint layer in the Supplement within the width and/or length of the projections.

In the way on the ledges perform additional image.

One option metallographic printing form recesses formed in cross section in the form of two angled one relative to the other planes, width, one of which is larger than the other more than 2 times.

For more on the width of the plane made the microrelief.

On both planes made the microrelief,

The height of the recess is from 20 to 150 microns.

For more on the width of the plane formed figure with depth engraving from 10 to 40 microns.

The width of the recess is more than 1.0 mm

In another embodiment, the metallographic printing plate is achieved by the fact that the recess is formed in cross section in the form located at different angles multiple planes, some of which are located across the width of the recess with education degrees.

The number of steps ranges from two to five.

At least one of the planes stages along its length and/or width of the executed at least one trench.

The height of the recess is from 20 to 150 microns.

The ratio of the height of the recess to the height of the steps is from 0.2 to 0.8.

On the surfaces of the steps formed figure with depth engraving from 10 to 40 microns.

The width of the recess is more than 1.0 mm

Under the proposed ways who have made valuable paper.

The invention is illustrated by drawings, where:

1 shows a deepening on metallographic printed form in two planes,

2 shows the groove on the metallographic printed form, in the form of steps

Figure 3 - same as figure 2 with depression,

4 is a recess with relief.

A method of manufacturing securities is the impact of metallographic printing form on a carrier, the transfer ink layer and the subsequent formation of a latent image to protect the paper from a fake.

The image is performed in the form of a set of projections of the paint layer and the hollows between them.

The width of the protrusions of the paint layer is more than 0.5 mm, and the paint layer of the projections performed with continuously changing optical density to enable a smooth or stepped transition from the saturated layer of paint to the midtones.

Continuously changing optical density of the paint layer is carried out within the width and/or length of the projections.

On the ledges perform additional image.

On the working surface of metallographic printing plates made of deepening to provide educational opportunities on the media hidden colorful images to protect the paper from a fake.

Recesses formed in the cross section in the form of two 1, 2, located n the d angle one relative to the other planes, width "and" one 2 of which more another 1 more than 2 times.

For more on the width of the plane 2 has a microrelief 3.

On both planes 1, 2 are made of the skin 3.

The height "h" of the recess ranges from 20 to 150 microns.

For more on the width of the plane 2 is formed figure with depth engraving from 10 to 40 microns.

Width "in" deepening is more than 1.0 mm

In another embodiment, the metallographic printing form recesses formed in cross section in the form located at different angles multiple planes 1, 4, 5, one 4, 5 of which are located across the width of the recess with education degrees.

The number of steps ranges from two to five.

At least one of the planes 5 degrees along its length and/or width of the executed at least one trench 6.

The height "h" of the recess ranges from 20 to 150 microns.

The ratio of the height of the recess to the height of the steps is from 0.2 to 0.8.

On the surfaces of degrees 1, 4, 5 formed figure with depth engraving from 10 to 40 microns.

Width "in" deepening is more than 1.0 mm

Trench 6 can be performed with different combinations of their location across the width and length of the grooves, which allows to obtain varying optical density on the image.

When the contact carrier with metallographic printed form, as to the th, as a rule, are special types of paper for the manufacture of the securities transfer ink layer of the recesses on the carrier. The image is a colorful line with continuously changing optical density of the paint layer, by visual consideration securities will be seen the transition from saturated colorful tone to halftone the width of the lines. This image obtained using metallographic printing form with steps or microrelief. On the image to the width of the visible areas of different optical density of the paint layer, the transition between them can be as smooth and speed. There is also a further illustration, for example, made in the form of wavy lines. You can also use the drawing in the form of numbers or labels.

The use of the present invention allow to obtain multiple graphic elements with elevated protective properties. Securities can be manufactured with a protective figure, made from dyed with varying optical density lines. Using this pattern on the banknotes, Bank documents, passports and other security papers will allow both automatic and visual authenticity control of securities. We can quickly change the characteristics of the obtained image of the paint layer, that increases the protective properties of the proposed image.

Thus, the invention improves the quality of the securities.
