The lenticular printing technology typically includes a phase lenticular printing items of information, usually two-dimensional information elements, such as words, pictures and/or graphic images on a support surface. Lenticular information typically contains at least two different items of information.

For example, the lenticular image may comprise a plurality of strips of images corresponding to the multiple images, each stripe composed of a set of adjoining line segments of the image near. Then on the lenticular elements of the information or image is superimposed lenticular raster, where each element of information�ation or an image strip is applied one cylindrical lens.

Device for method implementation contains mechanism of base sheet movement in longitudinal direction, relief roller, which rotates in respect to horizontal axis, coating film for covering roller surface. The front end of mentioned coating film is installed downstream from the lowest position of rotating relief roller. Facility of suspension supply is installed between coating film and base sheet. Device provides formation of the first field with coating layer of larger thickness on the surface of base sheet, and second filed with coating layer of smaller thickness or almost without this layer.

SUBSTANCE: method of forming frost work involves feeding water into an airtight housing, feeding hydrate-forming gas under pressure, maintaining given pressure and temperature conditions for the entire duration of formation of gas hydrate deposits. Hydrate-forming gas is fed at pressure a little higher than equilibrium, needed for formation of gas hydrate compounds at given temperature of the surface of the walls of the housing. Given temperature and pressure conditions are maintained for the entire duration of formation of gas hydrate deposits. Water is applied on the translucent walls of the housing by spraying. Maintenance of temperature and pressure conditions continues for the entire duration of retention of the frost work on the walls in form of gas hydrate deposits. The frost work can be altered via dissociation of the formed gas hydrate deposits by reducing pressure of the hydrate-forming gas to a value below the equilibrium value. Frost work is formed once more.

EFFECT: simple, fast programmed change of frost work and display of frost work at any temperature.
