Method of production of packaging material provided with repeating pattern made with printing ink

FIELD: packaging industry.

SUBSTANCE: method of manufacturing a packaging material is proposed, according to which the web of paper or cardboard is provided with the repeating pattern made with printing ink, which is printed directly on the surface of the web of paper or cardboard, after which the web is rolled onto the storage bobbin prior to additional processing. The web of paper or cardboard, prior to winding onto the storage bobbin is machined, whereby the selected areas of the rough surface of the web of paper or cardboard are flattened in the manner and to the extent that the printed pattern made with printing ink in all of these flattened areas is flush with the remaining areas of the surface of the web of paper or cardboard or below this level. At that the web provided with printing ink is provided with the repeating pattern of fold lines through which bending is facilitated.

EFFECT: reduced costs.

SUBSTANCE: base is subjected to pressure by placing it in contact with a stamping die. The stamp has a micro-proceeded site designed to create the diffraction pattern on this basis. The base comprises a printed paper or cardboard sheet varnished on the site of contact of the stamping die with the base. The stamp has also a plain section to create on this basis, except the diffraction pattern, a site with high degree of gloss.

EFFECT: invention enables to create a simple and economic mode of applying a visual label on the base.

FIELD: textiles, paper, hygiene.

SUBSTANCE: proposed method of manufacturing hygienic paper products involves stages, in which a continuous paper sheet is supplied and moving this continuous paper sheet in the direction of its longitudinal stretch. A recurrent decorative structure is applied on the sheet relative to the longitudinal stretch of the sheet as the first design using the first drum. A recurrent functional structure is applied on the sheet relative to the longitudinal stretch of the sheet as the second design using the second drum. Simultaneous speed control of the repeating surface of the continuous sheet and phasing between the first drum and the second drum is performed, in order to phase the first design and the second design one relative to the other to obtain one and the same recurring spatial interrelation with each other on the whole longitudinal stretch of the continuous sheet. In this case the lengthening of the sheet is controlled due to contact zones during supply at the inlet and contact zones during discharge at the outlet before and after the stage of application of the first design and/or the stage of application of the second design and relaxing of the sheet after it leaves the contact zone during unloading at the outlet.

EFFECT: improved outward appearance of the product.

SUBSTANCE: on the engraved surface of a printing form there are separate areas almost touching each other, with three different values of engraving depths. The printing form is used in metallographic printing of grey scale image, depicting a three dimensional object, by manipulating light and shade and/or plastic effects.

EFFECT: well distinguishable three dimensional image is obtained.

SUBSTANCE: steel printing form for deep printing contains on its surface at least one first section with printing structures, meant for producing an imprint by deep printing method, and at least one second section with structures intended for stamping, size of which is less than 100 micrometers. Parts of structures which are closest to the surface of printing form are positioned at a distance from 20 to 100 micrometers below level of printing form surface.

EFFECT: ensured stamping of securities and their simultaneous printing with usage of a single steel printing form for deep printing, and also high protection of securities from forgery is ensured.

SUBSTANCE: data carrier 14 with forgery-protecting imprint 1 made by metallographic printing method consists of several contrasting structural elements 2,3,4,5,7,22, positioned with precise alignment to each other, while one portion of these structural elements 3,4,5,7 is made relief-type and can be sensed by touch, and other portion of structural element 2, 22 is made flat and undetectable by touch.

EFFECT: exceptionally high level of protection.

FIELD: information medium sealed up by the method of metallographic printing, method for its manufacture, as well as a printing plate suitable for the purpose and the method for its manufacture.

SUBSTANCE: the information medium, first of all a bank note, securities or a similar document, which has at least one sealed up section (13) and at least one separate section (14) practically completely encircled by this section. The mentioned section (13) and the separate section (14) are sealed up by the metallographic method, and both sections are sealed up by paint coats of a different thickness and differ from one another.

EFFECT: provided a high degree of protection against forgery of the information medium.
