Printed matter and method for its manufacture (modifications)

FIELD: printing arts and concerns the printed matter with an image concealed from visual observation.

SUBSTANCE: the printed matter has a medium with the main image applied onto it transferred by a regulated raster with a preset angle and lineature, and at least with one additional image concealed from visual observation transferred by a raster with a deformed structure with a possibility of identification of the concealed image at imposition of a reference template onto the printed product. The concealed image is made for visualization in half-tones or in a contour at imposition of a reference template representing a transparent base with a linear raster applied onto it, whose angle and lineature are identical to the preset ones.

EFFECT: enhanced degree of protection of the printed matter at a use of a sufficiently simple reference template.

FIELD: engineering of protection elements.

SUBSTANCE: protection element 2 of plastic laminate 1 with surface ornament 12 mosaic-composed of surface elements 13,14,15, while plastic laminate 1 has shaped layer 5 positioned between surface 4 and protective 6 layers. Light 11 falling on boundary surface 8 between shaped 5 and protective 6 layers, is reflected, while at boundary surface 8 structures 9 are formed of optical effect of surface elements 13,14,15. in surface ornament 12 at least one pair 14,15 of surfaces is positioned, formed by first 14 and second 15 surface elements. Each surface element 14,15 has diffraction structure {B(x,y,T)}, produced by superposition of grid structure {G(x,y)} onto profiled structure {R(x,y)}. In first surface el 14 vector 16 of grid structure {G(x,y)} and vector 17 of profiled structure {R(x,y)} are practically parallel to each other, and inside second surface element 15 vector 16 of similar grid structure {G(x,y)} and vector 17 of similar profiled structure {R(x,y)} enclose practically a right angle, vectors 16 of grid structures {G(x,y)} in both surface elements 14,15 are practically parallel. Spatial frequency fR of both relief structures {R(x,y)} is more than 2500 lines in one millimeter, while spatial frequency fR of profile is at least ten times greater than spatial frequency fG of both grid structures {G(x,y)}.

EFFECT: protection element is hard to copy and has bright surface drawing altering on rotation or inclination, authenticity of element is easily checked by simple means.

FIELD: polygraphic technologies, methods for manufacturing polygraphic elements related to category of elements providing protection of polygraphic production from forgery.

SUBSTANCE: method for creating a concealed image within counter-forgery protective elements of polygraphic products includes, for special protective element consisting of multiple intersecting lines, forming an offset for a portion of bitmap lines utilized to make ornament of aforementioned protective element, for half the step of bitmap line step. For aforementioned special protective element firstly two even bitmap fields are formed, created by means of linear bitmap with similar line positioning and relative area of bitmap elements in first bitmap field 60-70% and in second bitmap field 15-20% and coinciding in size with special protective element with displayed dark portions of ornament on first bitmap field and light portions of ornament on second bitmap field. Onto aforementioned bitmap fields image in form of label and/or drawing is applied, positioned evenly relatively to boundaries of aforementioned fields, which is then cut out, and formed special space is filled with same bitmap with offset for half step of bitmap lines, basic special protective element is repainted for forming of special protective mask, wherein white elements remain white while dark elements become transparent, then special protective mask is positioned on first bitmap field and second bitmap field on special protective mask for producing a model of special protective element with concealed image.
