Document Type and Number:
WIPO Patent Application WO/2016/165145
Kind Code:
A1
Abstract:
Disclosed are a pattern for enhancing a dynamic optical variable anti-counterfeiting effect and a manufacturing method therefor. The pattern for enhancing a dynamic optical variable anti-counterfeiting effect is composed of a full-version colored printing body and a colored printing body with high and narrow three-dimensional line patterns; the colored printing body with the high and narrow three-dimensional line patterns is stacked and printed on the full-version colored printing body; the colored printing body with the high and narrow three-dimensional line patterns is in a shape of combined lines comprising curved lines, straight lines, a dot matrix or a combination thereof; a line clearance is 100 to 300% of a line width, and a line height is 10 to 100% of the line width; and the color of the colored printing body with the high and narrow three-dimensional line patterns and the color of the full-version colored printing body are gamut-space complementary colors or are obvious in visual difference. The pattern tilts or rotates along with printing products and generates a bright color change along with a visual continuous dynamic optical variable effect namely inclination. A strong color drifting effect is generated by horizontal rotation. The pattern is visible, easy to recognize, resistant to copying, difficult to counterfeit, and suitable for industrial application.
