Printed material printed with pattern with triple visual effect, and preparation method thereof

Abstract

The invention provides a printed material printed with a pattern with a triple visual effect. The pattern with the triple visual effect is formed by overprinting an engraved gravure printing form on afluorescent printing form; and lines of the fluorescent printing form are at least divided into two parts with color difference. Under the irradiation of an ultraviolet light source, a bright and colorful fluorescent shading pattern can be shown, and in addition, under the observation from different angles, fluorescence and a pattern at the engraved gravure part are combined to present a specialvisual effect, so that the visuality, the artistry, the interestingness and the antifalsification of a recess engraving picture are increased, the defect of single color of a traditional recess engraving picture is broken through, and the application scenario of the technology is further extended.

Description

technical field [0001] The invention relates to the technical field of printing inks, and relates to a printing substrate printed with patterns with triple visual effects and a preparation method thereof. Background technique [0002] The engraving and gravure printing technology is an anti-counterfeiting method widely used in the banknote printing industry. Different lines and dots are used to express the light and shade and the depth of the pattern. The pattern structure is unique and the printed product has a good feel. Because the original plate is engraved by hand, the plate-making process is extremely difficult, and it has strong artistic expression and anti-counterfeiting performance. Due to these advantages, the current gravure engraving process in the industry is mainly used in the fields of banknotes and stamps, and there are very few intaglio artworks other than banknotes. The intaglio sculpture itself is also an art category. As a non-banknote intaglio work, it ...

Problems solved by technology

[0004] Chinese patent CN 103895374 provides an anti-counterfeit pattern with an optically variable structure. The pattern is composed of lithographic lines and gravure embossed embossed lines. sexually deficient

[0005] Chinese patent CN 1262430 provides a data carrier with an optically variable structure, which produces a tilt effect when viewed alternately vertically and obliquely, but the printed body is arranged on the side of the relief structure, requiring high process precision

Although engraving gravure printing technology has a good pattern structure and visual hierarchy, due to technical factors, it limits the richness of color, visual appearance and anti-counterfeiting effect of this type of printing.
