Guides markers, for example, optical reader, are used for operations at the completion of packing, such as forming, sealing, packing, etc. Such guides markers are sometimes called register marks. Register label optical reader provide during printing on the packaging laminated material in place on the packaging laminated material type, for example, a decoration or information about the product. The problem with such registration marks, is that they consumed a considerable part of the material which becomes the outer surface of the packaging. Another problem is that such registration label must be created on the basis of print, well compatible with the operations previously performed on the fabric. The poet is the tsya desirable the provision of improved feeding markers on the network of the packaging laminate.

Brief description of drawings
Fig.1 schematically illustrates a network of packaging material, which as namagnichivaemost particle packing material secured spots namagnichivaemost ink according to variant embodiments.
Namagnichivaemost ink is provided so that on the packaging laminated material could be namagnichivaemost part, and this layered packaging material should be used to form, for example, food packaging, such as beverage and food containers, or containers for primary or secondary products of the cooking Linapacan. Inks contain namagnichivaemost particles, imparting magnetic properties nominativus parts.
Ink additionally contains a solvent. The purpose of the presence of the solvent may consist in maintaining a system for the distribution of ink, current at the time of printing. The solvent can be water-based or based on the monomer. Examples of solvents are ethanol, ethyl acetate, water, isopropanol, glycol or inhibiting solvent.
Ink additionally contain a binder, such as an acrylate, a styrene-acrylic copolymer, polyurethane, nitrocellulose, polyamide or latex. The binder may contain a mixture of several components, for example, from those mentioned above, to make the ink required properties. The considered properties are to facilitate the dispersion and stabilization of the magnetic particles in the ink, the transfer of the magnetic particles during the printing process, to give adhesion to the substrate on which the printing, i.e., the layer of the layered material. Additional properties consist in the protection of the magnetic particles after printing and providing the desired properties of the printing. For example, one component of the binder can serve as a dispersing agent, designed for uniform dispersion of magnetic particles in which emilah, while the other can serve as an adhesive for laminates, etc. To provide an ink suitable for high-speed printing, the amount of binder should be 20-60 percent by weight of the ink, i.e., the mass of raw material. It was found that the appropriate amount is 40-60 percent. Also suitable and the use of 50-55 percent.
The ink may optionally contain additives such as waxes and/or antifoams. Suitable waxes may be a polyethylene, polypropylene or polytetrafluoroethylene, polysiloxane, polyamide, ethylene vinyl acetate, ethylenebutylene, ethylenically acid and so on, the Amount of wax can vary, but it should be enough to prevent ink from otmerivanija or matania. Suitable antifoams can be a silicone or mineral oil. The number of protivovospalitel should be sufficient to prevent ink from foaming during printing on a moving network, especially when high-speed printing.
Ink can be prepared by mixing namagnichivaemost particles with the binder, for example, by continuous stirring or mixing. Adding particles that can get into the magnetized part, may be PR is ripped here when the mixture is about 40-50 degrees Celsius, and then directly enter any additives, for example, protivovospalitel and/or waxes, and liquid, so that the ink is ready to use.
Namagnichivaemost ink can be hematite or maghemite, or a combination thereof. These minerals are suitable for food packaging, because there are no restrictions regarding if they can be in contact with food. The number namagnichivaemost particles is 15-40 percent by weight of the ink, preferably, 30 to 35 mass%.
It was found that the size namagnichivaemost particles, i.e., the length across the particle diameter and so on, depending on the intended shape of the particles, gives a more or less advantageous properties of the residual magnetic field (residual magnetization) when applying magnetic labels on the spot, printed namagnichivaemost ink. The smaller the particles, i.e. the size of 0.1 ám, the more they can be dispersed, but each particle, of course, will support a smaller residual magnetic field (remanence). Also, depending on the choice of binder, solvent, etc., the dispersion of small particles in practice can be problematic, since during the preparation and processing of ink may be prone to lumping small frequent the TS. On the other hand, large particles, i.e. particles with a size in one or a few microns, of course, may not be so subjected to dispersion, as smaller particles, but each particle can maintain a higher residual magnetic field (remanence), and be prone to lumping of such particles will be less noticeable. It was found that a further increase in particle size does not increase the total residual magnetic field (remanence), which can be maintained with this ink, in which the spots are held constant. Thus, an acceptable size namagnichivaemost particles may be 0.1-2.5 μm. Preferred dimensions for the variant embodiments can be 1-8 μm or 0.4 to 1.5 μm with an alternative embodiment. The approximation of small particles can be assumed, for example, the presence of particles with a size of about 0.3 microns to provide an acceptable compromise between the dispersion and the emergence of commersonia. Another approach may involve the presence of particles with a size of about 1 μm, so that each particle could provide a significant magnetic field and to minimize commersonia. In yet another variant embodiment may have a particle size of about 0.4, 0.5, and 0.6 or 0.7 μm, which provides both an advantage for the other two is reamers, above. Here the size specified as "average"should be interpreted in the light as the particle shape, which probably does not give the possibility to measure the geometric distance and the fact that there is a natural variation in the size of the particles caused by their preparation. For example, you can choose the size of the particles equal to one-half micron, but such particles are prepared by grinding and will have a slightly irregular shape. Thus, the average particle size should be half microns in its largest possible direction, while its size is at least the direction should be only of 0.35 μm. In addition, for the greatest direction 80 percent of the particles can be spread from 0.45 to 0.55 μm, while the remaining 20 percent can be outside of this range, especially for smaller particles, which is caused by grinding. This example, of course, applicable to any selected size. The scatter can be reduced by monitoring the particles after grinding.
Fig.1 illustrates a network 100 of the packaging material, where provided many namagnichivaemost areas 102. It is preferable that namagnichivaemost area when printing were distributed so that there is at least one magnetized region 102 on the package 104, the way the controls from the packing material. To reduce consumption of the magnetic material, i.e., consumption namagnichivaemost ink, a magnetic field can be provided in the form of spots, etc. on areas where it should be posted by magnetic tags. Since the accuracy of the locations between the stamp and the location of the magnetic labels are limited, compared with the same situation associated with optical labels, it is preferable that the stains were slightly larger than the actual size required for the magnetic label. Thus, it is possible to work with any reasonable deviation. Thus, the spot is equipped with namagnichivaemost particles, which can provide a magnetic labels, and, as will be explained in more detail below, depending on the shape and size of the spots, they will be provided with more complex information through modulation of magnetization. It is preferable that the packing material was a laminate, or a single layer of material such as a polymeric material. Namagnichivaemost region 102 supply namagnichivaemost ink, as demonstrated above, for example by printing. The packaging material may be a layered material, which may contain a layer of paper on which to print namagnichivaemost region 102, and one or a few is to plating layers of plastic. Here, the term "coating of plastic" should be understood as any coating comprising polymers suitable for food containers. The packaging laminate may also contain a layer of metal foil. To be able to read and write magnetic labels through a layer of metallic foil is preferable that the metal would not be ferromagnetic, such as aluminum. It is preferable that the printing namagnichivaemost areas occurred on the side of the layer so that the prints on the layered material would be directed where it is expected to inner space formed by the package. Thus, the magnetic printing labels should not interfere with external printing, for example, decorative design or product information on the packaging. It is preferable that the printing was using namagnichivaemost ink, as demonstrated above.
