Referring to fig. 1, fig. 1 is a schematic structural diagram of a card according to an embodiment of the present application.

As shown in fig. 1, the card provided in the embodiment of the first aspect of the present application includes a card body 100 and a three-dimensional layer 200, where at least one surface of the card body 100 is provided with the three-dimensional layer 200, where the three-dimensional layer 200 includes a first printing layer 201 and a cold wave layer 202, the first printing layer 201 has a first surface facing away from the card body 100 and a second surface facing the card body 100, and the cold wave layer 202 is disposed on a side of the first surface of the first printing layer 201.

The following terms in this application are explained first:

printing a layer: and printing the structural layer with the three-dimensional shape according to a required pattern by using a printing technology, wherein the printing technology can be a 3D printing technology.

Cold-ironing layer: the material is contacted with the printing layer under the action of pressure by using cold ironing equipment, and the material is transferred to the structural layer formed by the printing layer at the temperature of about 100 ℃ through the surface energy characteristic of the printing layer.

A card body: the card is based on a card and comprises a winding layer, a printing layer and a protective layer which are arranged in a laminated mode. The winding layer is formed by a plurality of layers of PVC sheets and a coil layer, and the winding layer is fixedly connected with the printing layer and used for covering the winding layer, so that the attractiveness of the intelligent card is enhanced. The material of the printing layer includes, but is not limited to, white PVC, colored PVC, transparent PVC, PET, PETG, PLA, etc. The protective layer is connected and fixed with the printing layer to protect the card body, and the protective layer is usually made of transparent material so that people can clearly see the printed content in the card body.

Next, explaining the three-dimensional layer 200 of the present application, the three-dimensional layer 200 is disposed on at least one surface of the card body 100, and includes a first printing layer 201 and a cold wave layer 202, wherein the first printing layer 201 is disposed on at least one surface of the card body 100, that is, the first printing layer 201 is disposed only on the front surface of the card body 100, or the first printing layer 201 is disposed only on the back surface of the card body 100, or both the front surface of the card body 100 and the front surface of the card body 100 are disposed with the first printing layer 201.

The first printing layer 201 may completely cover a certain surface of the card body 100, i.e. in the thickness direction of the card body 100, the projected area of the first printing layer 201 is equal to the projected area of the card body 100. Alternatively, the first printing layer 201 may cover a partial region of one surface of the card body 100, that is, a projected area of the first printing layer 201 in the thickness direction of the card body 100 is smaller than a projected area of the card body 100. The partial areas may be continuous whole-piece areas to form a continuous three-dimensional pattern, or discontinuous areas distributed at intervals to form a three-dimensional pattern in combination.

The cold wave layer 202 is formed by contacting the substance with the first printing layer 201 under pressure and transferring the substance to the first printing layer 201 by means of the temperature of about 100 ℃ and the surface energy characteristics of the first printing layer 201. In addition, in the formation process of the cold wave layer 202, the card body 100 is less affected by a temperature of about 100 ℃.

The forming process of the three-dimensional layer 200 can be understood as that after the card body 100 is printed, the image-text part with the convex effect, i.e. the first printing layer 201, is formed on the surface of the card body 100, and the image-text part is higher than the non-image-text part along the thickness direction of the card body 100 to form a latent image. Optionally, the first print layer 201 is a base coat. Then, the first printing layer 201 is processed in a cold wave device, the substance is contacted with the latent image under the action of pressure, and the substance is transferred to the first printing layer 201 to form a cold wave layer 202 by means of a certain temperature, generally about 100 ℃, and according to the surface energy characteristics of the first printing layer 201, and finally the three-dimensional layer 200 is obtained.

According to the card provided by the embodiment of the application, according to the required three-dimensional pattern, the printing technology is firstly utilized to form the first printing layer 201 with the three-dimensional shape on the card body 100, then the cold ironing processing is carried out on the first printing layer 201 to form the cold ironing layer 202, and the first printing layer 201 and the cold ironing layer 202 jointly form the three-dimensional layer 200 with the three-dimensional pattern effect. On one hand, because the printing technology can form abundant three-dimensional patterns, the formed three-dimensional layer 200 has a good three-dimensional effect, so that the card has a good visual effect and a good tactile effect, and a user can have good visual experience and tactile experience. On the other hand, by forming the cold wave layer 202 by cold wave processing on the first print layer 201 by using the cold wave technique, the formed three-dimensional layer 200 can have a better appearance effect, and the visual effect of the card can be further improved. Also, since the temperature required for the cold ironing process is low, the influence on the card body 100 is small. In addition, the first printing layer 201 only needs to print on the card body 100 according to the designed pattern to obtain the three-dimensional structure, and a template is not needed, so that the card is not only simple to manufacture, but also convenient for personalized setting.

In some alternative embodiments, the cold wave layer 202 overlays the first print layer 201.

In these alternative embodiments, the projected area of the cold wave layer 202 in the thickness direction of the card body 100 is equal to or larger than the projected area of the first print layer 201, so that the cold wave layer 202 covers the first print layer 201. When the projected area of the cold wave layer 202 is equal to the projected area of the first printing layer 201, it can be understood that the first printing layer 201 is a continuous three-dimensional structure layer laid on the whole surface of the card body 100, and the cold wave layer 202 is stacked on the first surface of the first printing layer 201. The projection area of the cold wave layer 202 is larger than that of the first printing layer 201, the first printing layer 201 is a discontinuous three-dimensional structure layer, the first surface of the first printing layer 201 is exposed on all surfaces, and the cold wave layer 202 completely covers the first surface of the first printing layer 201, so that a three-dimensional effect can be better presented.

Thereby increasing the stereoscopic impression and the aesthetic property of the surface of the card and meeting the individual requirements of users. Moreover, the plurality of protruding portions are provided at intervals on the surface of the card body 100, and each protruding portion is light in weight and less likely to come off compared to the continuous one-piece first print layer 201. In addition, even if some of the protrusions are detached, the influence on the overall three-dimensional pattern effect of the body layer 200 is small, thereby increasing the durability of the card.

In some alternative embodiments, as shown in fig. 2, among the plurality of protrusions, the protrusions located at different regions of the card body 100 have the same or different shapes in cross section in the thickness direction of the card body 100.

Alternatively, the protruding portion may be any one of a rectangular body, a cylindrical body, a trapezoidal body, a semicircular body, a conical body, and the like, and may be freely combined. It is understood that the shapes of the cross sections of the protruding portions on different areas on the card body 100 in the thickness direction of the card body 100 are the same, for example, are all semicircular, and the plurality of semicircular shapes form a three-dimensional pattern structure; alternatively, the cross-sectional shapes of the protruding portions on different areas of the card body 100 in the thickness direction of the card body 100 are different, for example, a combination of a semicircular shape and a rectangular shape forms a three-dimensional pattern structure, thereby presenting different textures and appearances.

In some alternative embodiments, as shown in fig. 2, among the plurality of protrusions, the protrusions located at different regions of the card body 100 may have equal or different thicknesses.

In these alternative embodiments, the heights of the protrusions located at different regions of the card body 100 are equal to form a three-dimensional pattern of the same height. The heights of the protrusions located in different areas of the card body 100 are not equal to form a three-dimensional pattern with high and low fall. Therefore, the difference of the thickness of the convex part of different areas is adjusted correspondingly according to the requirement of the designed pattern.

In these alternative embodiments, the substance is in contact with the first print layer 201 under pressure, and the cold-stamping layer 202 is formed on the first print layer 201 by means of the temperature of about 100 ℃ and the surface energy properties of the first print layer 201, wherein the substance may be a metallic material.

Alternatively, the cold-stamping metal layer may be a precious metal layer such as a cold-stamping gold foil layer or a cold-stamping silver foil layer.
