PATTERN WITH IMPROVED DYNAMIC OPTICALLY VARIABLE ANTI-COUNTERFEIT EFFECT AND METHOD FOR MANUFACTURE THEREOF Russian patent published in 2018 - IPC B41M3/14 

FIELD: images forming devices.

SUBSTANCE: present invention relates to a pattern with an improved dynamic optically variable anti-counterfeit effect and a method for manufacturing it, a pattern with an improved dynamically optically variable anti-counterfeit effect consists of a full-page color printing plate and a color printing plate with high narrow stereoscopic lines, the color printing plate with high narrow stereoscopic lines is printed over the full-color printing plate, the color printing form with high narrow stereoscopic lines has a shape formed by combined lines including a curved line, a straight line, a dot pattern, or a combination of these elements, the line spacing being between 100 and 300 % of the line width, and the line height is between 10 and 100 % of the line width, the color of the color printing plate with high narrow stereoscopic lines is a color that is complementary in the color palette space with respect to the color of the full-page color printing plate, or a color visually significantly different from the color of the full-page color printing plate.

EFFECT: present invention provides the possibility of creating a continuous optically variable effect when the printed article is tilted or rotated, namely the ability to create a distinct effect of color change when tilted and the effect of a strong color shift when rotating in the horizontal plane, the said effect is visual, easily recognizable, copy-protected and difficult to forge.
