Description

TECHNICAL FIELD

[0001] The utility model relates to the packaging forming technical field, concretely to a packaging box with multi-direction latent image medium. BACKGROUND

[0002] The surface finishing process of exquisite packaging is various, mainly including film covering, gold stamping, UV oil coating, concave-convex pressing, die cutting and indentation, reverse frosting, ice point snowflake and the like. These processes improve the visual effect and texture of the packaging through different technical means, for example, the film covering process can increase the gloss and waterproof and stainproof performance of the paper, the gold stamping gives the packaging a metallic texture and high-end feel, and the UV oil coating can enhance the delicate level and artistic effect of the graphics and texts, in addition, the concave-convex pressing process makes the packaging surface produce a three-dimensional embossing effect through mold shaping, increasing the visual impact. The comprehensive application of these processes not only improves the added value of the product, but also meets the market demand for high-end packaging.

[0003] The reverse UV process is an advanced surface finishing process technology that forms a high-gloss and matte contrast effect and has strong frosting texture and three-dimensional tactile sensation on the surface of printed matter, and is widely used in high-end gift boxes, cosmetic packaging, book covers and other packaging materials that require three-dimensional and high-end feel. The reverse UV process prints transparent reverse ink on the non-glossy part of the design, then prints full-plate UV gloss oil and solidifies, so that the gloss oil and reverse ink interact to produce a cohesive reaction, forming a matte or pitted effect, while the high-gloss part forms a mirror-like high-gloss effect. This reverse UV effect not only enhances the visual impact and aesthetics of the printed matter, but also improves the light resistance, heat resistance and moisture resistance of the ink, and effectively protects the print, but its visual effect is relatively single (mainly the contrast between high gloss and matte).

[0004] Therefore, it is urgent to develop a packaging box with low cost and multi-direction latent image effect to solve this technical problem. UTILITY MODEL CONTENT

[0023] Embodiment 1

[0024] As Figures 1-2 The embodiment discloses a packaging box with a multi-direction latent image medium, comprising a packaging box body 1, at least one side of the packaging box body 1 is provided with a multi-direction latent image medium 2, the multi-direction latent image medium 2 comprises a texture layer 21 and a latent image appearance layer 22, the texture layer 21 is coated on the surface of a substrate 3 and is provided with an array of blank areas 211; the latent image appearance layer 22 comprises a first part in contact with the texture layer 21, and a second part in contact with the surface of the substrate 3; the latent image appearance layer 22 is composed of an array of protrusions 221, the protrusions 221 are micro protrusions, and the array mode of the protrusions 221 is consistent with the array mode of the blank areas 211 provided by the texture layer 21, and the height of the latent image appearance layer 22 is greater than the height of the texture layer 21. The multi-direction latent image medium 2 has at least two directions of latent images, so that the multi-direction latent image medium has the visual effect of double or more latent images under light observation.

[0025] The array mode of the protrusions 221 is that one protrusion 221 is taken as a center point, and other protrusions 221 are arranged and extended along the intersection points of a pattern, and the pattern is a seamless tiling pattern formed by arranging equilateral triangles, squares and hexagons with the same side length around a vertex.

[0026] The texture layer 21 is printed by base oil, and the latent image appearance layer 22 is printed by surface oil and is formed by condensation. The equipment used in the production of packaging printing is an “8+1” color offset printing press, wherein the “1” is a web roller oiling unit, the base oil is printed by one of the color offset groups, and the texture layer 21 is formed after drying, the surface oil is transferred to the texture layer 21 on the surface of the substrate 3 by the web roller of the oiling unit, and the protrusions 221 are quickly condensed to the blank areas 211 of the texture layer 21 due to the mutual exclusion of the surface oil and the base oil, and the micro protrusions are quickly cured and formed by a UV light source, and the embodiment uses a 120-mesh web roller.

[0027] The array of the protrusions 221 includes protrusions 221 with different shapes, sizes and heights. This is due to multiple factors such as uniformity of surface oil film coating, condensation speed, adsorption of packaging substrate, UV drying speed, etc., and the array of the protrusions 221 includes protrusions 221 with different shapes, sizes and heights, but under the action of the same size blank areas 211 provided by the texture layer 21, the appearance difference of the micro protrusions 221 is not too obvious.

[0028] Under the action of the micro-convexity, the array of micro-convexities can hide up to five layers of information after modulation. At the same time, due to the multi-angle dot arrangement of the non-modulated area, when viewed from a modulation angle, the dots at other angles will form a relatively regular light occlusion and produce obvious periodic texture changes, forming a non-modulated refractive latent shadow texture, thus enriching the finishing effect of the packaging box surface.

[0029] Preferably, the medium of the multi-directional latent image also has tone variations, which are controlled by tone variations of the selected image.

[0030] Example 2

[0031] The difference between this embodiment and Embodiment 1 is that a frosted effect medium can also be provided around the multi-directional latent image medium 2; otherwise, it is the same as the embodiment.

[0032] like Figure 3 As shown, in this embodiment, a conventional frosted effect medium 4 is set around the multi-directional latent image medium 2. Since the frosted effect is formed by the reaction and condensation between the top oil and another solid-printed base oil, the solid-printed base oil has no control effect on the condensation position of the top oil. The position of the formed micro frosted protrusions 41 is random. Therefore, in application, it is necessary to measure the size range of the micro frosted protrusions 41 on the conventional frosted effect medium in advance, so as to adjust the size of the blank area 211 on the texture layer 21, so that the size of the micro protrusions 221 formed by controlling the condensation position is very close to the size of the micro frosted protrusions 41 on the conventional frosted effect medium, thereby ensuring the visual fusion effect of the two.

[0033] It is important to note that Figure 3 The random positions of the tiny frosted bumps 41 in the frosted effect medium area shown are for demonstration purposes only and do not represent the random distribution during actual production.

[0034] The packaging box with multi-directional latent image medium in this embodiment has a visual effect of double or more latent images under refractive observation, and at the same time has a frosted visual and tactile effect. Furthermore, the multi-directional latent image medium can be perfectly combined with the frosted effect medium formed by ordinary reverse UV process, and has almost the same molding process as the frosted effect medium. The molding process is simple, fast, efficient, and low cost, which enriches the visual and tactile effects of the packaging box and the consumer experience.

[0035] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
