Cliche for mastic stamp

 

The invention relates to the performance of structural elements of the stamps to run prints at wetting stamp ink, namely, to the production of a cliche for these stamps. Cliche for mastic stamp includes a relief plate to the circuit elements in the form of protrusions, forming its outer surface mirroring seal, and spacing elements in the form of depressions. Gap elements filled with additional print elements in the form of many small speakers above the surface depressions of dot elements arranged at the intersections of the guide curves. The front surface of the protruding point of the elements is in the same plane with the outer surface of the protrusions forming a mirror image of the seal impression. The smallest size of the point elements is in the range from 0.05 to 0.2 mm with a distance between them of not less than 0.025 mm At least one point of the element can be offset from the intersection of the guide curves or rotated at some angle relative to the initial position of the other point elements. The minimum distance from the printing elements to the next print will complement the shaft elements is 20-80% of the area in terms of the relief plate. This provides a reduction of the specific load on the circuit elements and control prints print. 5 C.p. f-crystals, 6 ill.

The invention relates to the performance of structural elements of the stamps to run prints using ink colors, and, to the manufacturing of a cliche for these stamps.

Known cliché for mastic stamps, including relief plate to the circuit elements in the form of protrusions, forming its outer surface mirroring seal, and spacing elements in the form of depressions (see US No. 2002124753 A1, 41 To 1/56, 12.09.02).

The protrusions embossed plate, forming a printed items being moistened stamp ink, leave an imprint on the paper when burned. Depression relief plates are whitespace elements and should not touch the surface of the paper when burned. The area of the front surface of the printing elements is, as a rule, from 5 to 15% of the total area in terms of the relief plate.

A disadvantage of the known design is the low reliability and low life, because during operation, due to the impact of the cliche dynamic nagae to produce prints different from those, which were obtained at the beginning of operation clichés. The accumulation of these differences leads to the fact that it becomes difficult to establish the authenticity of the seal produced so cliche.

Task patentable invention is to improve reliability and increase lifetime cliche.

The technical result is to reduce the strain acting on the circuit elements when the affixation of the seal by reducing the specific load per unit area of the front surface of the printing elements when burned.

The specified task and the technical result is achieved by the fact that in a cliche for mastic stamps, including relief plate to the circuit elements in the form of protrusions, forming its outer surface mirroring seal, and spacing elements in the form of depressions, gap elements filled with additional print elements in the form of many small speakers above the surface depressions of dot elements arranged at the intersections of the guide curves belonging to two families of curves, and the front surface of the protruding point of the elements is in the same plane with Lavoisier point elements is in the range from 0.05 to 0.2 mm, and the distance between adjacent dot elements is not less than 0.025 mm

And also that at least one dot element is offset from the intersection of the guide curves.

And also that at least one dot element is rotated at some angle relative to the initial position of the other point elements.

And the fact that the minimum distance from the printing elements to the closest of print elements is not less than 0.25 mm

And the fact that the total area of the front surface of the printing elements and additional printed items is 20-80% of the area in terms of the relief plate.

The smallest size of the dot printing element is determined by the fact that the point element of a smaller size may not be moistened stamp ink when dipping the stamp into the ink pad. Thus, point item size less than 0.05 mm may be unstable leave the prints or not to leave any impression at all.

The maximum size is limited by the fact that increasing the size of the dot print element can lead to mixing it with the punctuation (commas, periods, quotation marks, etc) and elements of the letters (i,

When you increase the maximum distance between adjacent dot elements reduces their number and, thereby decreasing their total area, thus reducing the desired technical result.

When reducing the distance between the point of print elements and circuit elements may merge (mixing) additional printed items with the main printed elements.

Cliches made in the form of a relief plate 1 from any material suitable for the manufacture of clichés, for example, rubber, or from any polymeric material, such as plastic or metal, etc. On the relief plate 1 is made of printed VSP, the word "PRIORITY" and framing the frame 4. On the relief plate 1 has a gap elements in the form of depressions 5, which surface is not wetted stamp ink when the affixation of the seal and does not touch the paper, on which the seal is affixed. Gap elements, namely, depression 5 filled with additional print elements in the form of many small protruding above the surface of the depressions 5-point elements 6 located at the intersection 7 of the guide curves 8 and 9 belonging to two families of curves. The smallest size in terms of point elements from 0.05 to 0.2 mm, and the distance between them not less than 0.025 mm, the cross-sectional Shape of dot elements 6 may be different - round, elongated along one axis, for example, oval, square, rectangular, or any other. The front surface 10 of point elements 6 is in the same plane 11 with a front surface 3 of the projections 2. The total area of the front surface of the printed elements 2 and additional elements 6 is 20-80% of the area in terms of the relief plate 1. This area of the facial surfaces of the printing elements can significantly reduce the power impact on them and, thereby, reduce wear and increase debt is inih) and other

In order to control the membership of the seal of a particular stamp, which features a patent-pending cliché, at least one dot element is displaced, for example, the value of=0.05 mm relative to the intersection of the guide curves 8 and 9 and/or rotated at some angle, for example angle=90relative to the initial position of the other point (see Fig.6). This allows you to create a mirror reflection of at least one individual imprint. Prints from additional offset printing elements can be grouped in such a way that when applying the stencil becomes visible or word, text, numbers, or special characters, or figures.

If the affixation of the seal to clichés applied some pressure to compress moistened with stamp paint the front surface of the printed elements. Since the total area of the front surface is increased, the reduced specific force and, respectively, significantly reduced the deformation of the printing elements due to the reduction of specific efforts. Because of this, the service life of clichés will increase significantly, compared with the known possibility of determining the membership of bear prints stamp with which they were received.
