The printed pattern is printed at the customized position; thereby, the corresponding pattern is printed on the substrate according to the user's preference, or the printed pattern is customized at a position on the substrate, thereby satisfying the individualized needs of the user.

It should be noted that, in the embodiment of the present invention, there is no special requirement for the drawing tool, as long as the drawing tool can apply pressure on a side of the supporting film 1 facing away from the first ink layer 2, so that the The first ink layer 2 may be printed on the substrate through a through hole in the microporous film 3, and a printed pattern may be formed on the substrate. In this embodiment, since the ink color of the first ink layer 2 is a single color, the printed pattern formed on the substrate by using the printed film is also Printed patterns with the same color.

In another embodiment of the present invention, the first ink layer 2 has a plurality of ink regions, and ink colors of adjacent ink regions are different, so that not only the printed film provided in the embodiment can be used on the substrate. A printing pattern adapted to different user preferences is formed, and a color printing pattern can also be formed, that is, the printing pattern is a printing pattern having a plurality of colors to further satisfy the individualized needs of the users.

In still another embodiment of the present invention, for certain demanding printed patterns (such as trademarks of some products or printed patterns preferred by most users), the first ink layer 2 has a predetermined pattern, that is, The first ink layer 2 has a pre-drawn pattern. When printing, as shown in FIG. 2, the user only needs to face the microporous film 3 away from the side of the first ink layer 2 toward the substrate 6, and The printed film is placed on the surface of the substrate 6, and then, by using the squeegee 7 on the side of the support film 1 facing away from the first ink layer 2, scraping from one side to the other in one direction, The predetermined pattern of the first ink layer 2 is printed on the substrate 6, thereby simplifying the operation of the user, and the use is convenient and quick.

The microporous film 3 has a predetermined pattern, that is, a plurality of through holes on the microporous film 3 form a predetermined pattern, and similarly, the user only needs to face the microporous film 3 away from the printing. One side of the first ink layer 2 faces the substrate 6, and the printed film is placed on the surface of the substrate 6, and then, with the squeegee 7 on the side of the support film 1 facing away from the first ink layer 2, By scraping from one side to the other in one direction, the predetermined pattern of the microporous film 3 can be printed on the substrate 6, thereby simplifying the operation of the user, and being convenient and quick to use.

In still another embodiment of the present invention, the first ink layer 2 and the microporous film 3 have The preset pattern, at this time, the predetermined pattern on the microporous film 3 is formed by the arrangement of the through holes. That is, the first ink layer 2 has a pre-drawn pattern, and the plurality of through holes on the microporous film 3 form a predetermined pattern, and the user only needs to deviate the microporous film 3 during printing. One side of the first ink layer 2 faces the substrate 6, is placed on the surface of the substrate 6, and then, with the squeegee 7 on the side of the support film 1 facing away from the first ink layer 2, from one side When the film is scraped to the other side in a certain direction, the common portion of the predetermined pattern of the first ink layer 2 and the microporous film 3 can be printed on the substrate 6, thereby simplifying the operation of the user, and being convenient and quick to use.

Preferably, in this embodiment, the preset pattern on the first ink layer 2 is the same as the preset pattern on the microporous film 3, but in other embodiments of the invention, the first ink The preset pattern on the layer 2 and the preset pattern on the microporous film 3 may also be different, and the invention is not limited thereto, as the case may be.

It should be noted that when the first ink layer 2 has a predetermined pattern, the non-pattern area in the same plane as the first ink layer 2 may be free of ink or may be filled with transparent ink. Moreover, when the predetermined pattern of the first ink layer 2 is a color pattern, in an embodiment of the present invention, the first ink layer 2 may be formed by one printing, that is, the first ink layer. 2 includes only one layer of the first ink layer, and the ink colors of the adjacent ink regions are different. In another embodiment of the invention, the first ink layer 2 is formed by layer printing, that is, the first ink layer. 2 includes a plurality of first ink layers, wherein the first ink layer of each layer is located in a predetermined pattern, and the ink color of the adjacent ink regions is different, and the non-pattern region is filled with a transparent ink, but the invention is not limited thereto. Subject to availability.

It should be noted that, in the printing film provided by the embodiment of the present invention, the squeegee 7 used in the printing process can be a common flat plate, such as a square ruler, does not require a professional squeegee, and does not require a dedicated screen and wire. The net fixing plate, compared with the screen printing in the prior art, reduces the professional demand for printing equipment. And reduce printing costs.

In an embodiment of the present invention, the printed film may further include a second ink layer 4 between the support film 1 and the first ink layer 2, and the second ink layer 4 is cured. The wear resistance is superior to the wear resistance of the first ink layer 2 after curing. Moreover, the adhesion of the first ink layer 2 material to the surface of the substrate is good, so that the printed pattern is firmly adhered to the surface of the substrate, and is not easily peeled off during transportation and use. In some cases, in consideration of factors such as production cost, optionally, the adhesion property of the first ink layer 2 material to the surface of the substrate is superior to the adhesion property of the material of the second ink layer 4 to the surface of the substrate.

With the printing film of the embodiment, after the pattern printing is completed on the surface of the substrate 6, the second ink layer 4 is positioned above the first ink layer 2, and the printed pattern formed by the material of the first ink layer 2 is protected. The abrasion resistance of the second ink layer material is superior to that of the first ink layer material, so that the printed pattern of the present embodiment has better wear resistance than the printed pattern in which the second ink layer is not provided.

Moreover, since the adhesion property of the first ink layer material to the surface of the substrate can be superior to the adhesion property of the second ink layer material and the surface of the substrate, the printed pattern can be more firmly adhered to the surface of the substrate, so that the printed pattern is Longer service life.

In the embodiment of the present invention, the material of the second ink layer 4 is preferably a transparent material, so that when the first ink layer 2 has a predetermined pattern, the second ink layer 4 is made to be the same as the first A filling ink of a non-patterned area of the ink layer 2 in the same plane.

In another embodiment of the present invention, the second ink layer 4 may further select a color non-transparent material, and at this time, the second ink layer 4 has the same preset pattern as the first ink layer 2, thereby After the pattern printing is completed, the printed pattern formed on the substrate 6 is protected, and the material used for the first ink layer 2 is saved. Optionally, in an embodiment of the invention, the material of the first ink layer 2 is a PU coating, and the material of the second ink layer 4 is a polyurethane ultraviolet curing (UV) coating. In a specific embodiment of the embodiment, the manufacturing method of the printed film may include: forming a second ink layer 4 on the surface of the support film 1; forming a first ink layer 2 on the surface of the second ink layer 4. At this time, the second ink layer 4 and the first ink layer 2 are both in a gel or viscous liquid state. That is, the UV coating as the second ink layer is not subjected to ultraviolet curing throughout the production process, and the second ink layer 4 and the first ink layer 2 on the obtained printing film are both in a gel state or a viscous liquid state. It should be noted that, when the printing film provided in this embodiment is used for pattern printing on the substrate, the second ink layer 4 and the first ink layer 2 pass through the through hole in the microporous film 3. Missed on the substrate.

Since the PU coating forming the first ink layer 2 is easily worn by the external environment after the printed pattern is obtained, the UV coating forming the second ink layer 4 has a high hardness, and after the printed pattern is obtained, the UV coating can be The film is cured under normal light or ultraviolet light, and therefore, the cured second ink layer 4 has a protective effect on the first ink layer on the printed pattern to protect the printed pattern from the external environment.

In another embodiment of the embodiment, the method for fabricating the printed film may include: forming a second ink layer 4 on a surface of the support film 1; and performing ultraviolet curing on the second ink layer 4; The first ink layer 2 is formed on the surface of the second ink layer 4. At this time, the second ink layer 4 is in a solid state, and the first ink layer 2 is in a gel or viscous liquid state. It should be noted that, when the printing film provided in the embodiment is used for pattern printing on the substrate, only the first ink layer 2 is leaked onto the substrate through the through holes in the microporous film 3. In this case, the second ink layer 4 functions mainly to enhance the adhesion between the first ink layer 2 and the support film 1.

In still another embodiment of the embodiment, the manufacturing method of the printed film may include: a second ink layer 4 is formed on the surface of the support film 1; a first ink layer 2 is formed on the surface of the second ink layer 4, and at this time, the second ink layer 4 and the first ink layer 2 are both in a gel form. Or a viscous liquid state; ultraviolet curing the second ink layer 4 and the first ink layer 2, at which time, the second ink layer 4 is solid, and the first ink layer 2 is gelatinous or viscous Thick liquid state. After the printing pattern of the printing film of the embodiment is used, as in the above embodiment, only the first ink layer is printed on the surface of the substrate, and the second ink layer 4 is mainly used to enhance the first ink layer 2 and the support. Adhesion between the membranes 1. In other embodiments of the present invention, the printing film is produced by other methods, and the invention is not limited thereto.

In another embodiment of the present invention, the adhesion property of the material of the second ink layer 4 to the surface of the support film 1 is better than the adhesion of the material of the first ink layer 2 to the surface of the support film 1, thereby enhancing the first ink layer 2 Adhesion to the support film 1 to better adhere the first ink layer 2 to the surface of the support film 1. The parameters of the adhesion performance of the second ink layer 4 and the surface of the support film 1 are not specifically limited in the embodiment of the present invention, as long as the first ink layer 2 is not easily ensured during transportation or production handling of the printed film. It can be detached from the support film 1.

It will be understood by those skilled in the art that during the fabrication of the printed film, the first ink layer and the second ink layer are in a solution state or a gel state, and the two directly contact each other, and there is inevitably a fusion of molecular layers between the surface materials. In general, the degree of firmness of the fusion is necessarily higher than the adhesion of the first ink layer to the surface of the substrate, and also higher than the adhesion of the second ink layer to the surface of the support film.

It should be noted that in the embodiment of the present invention comprising the first ink layer and the second ink layer, the materials of the second ink layer and the first ink layer are different. The first ink layer as described in the above embodiments is a PU coating, and the second ink layer is a UV coating. Since the adhesion property of the PU coating is superior to the adhesion property of the UV coating, the abrasion resistance of the UV coating is superior to that of the PU coating. The price of PU coating is higher than UV coating Therefore, the combination can simultaneously improve the firmness and wear resistance of the printed pattern, and at the same time reduce the cost of the printed film.

In addition, similar to the material selection of the first ink layer 2, the material of the second ink layer 4 may also be a resin material or a resin composition, the resin composition including a resin material and a pigment, a solvent, At least one mixed substance of the auxiliary agent and the filler. Among them, the resin material preferably includes a natural resin, a phenol resin, an amino resin, an epoxy resin, a urethane resin, an acrylic resin, or the like.

When the first ink layer and the second ink layer are selected, the wear resistance of the second ink layer material after curing is superior to that of the first ink layer material after curing. Secondly, the adhesion performance of the second ink layer material to the surface of the support film is better than the adhesion performance of the first ink layer material and the surface of the support film, or the adhesion property of the first ink layer material to the surface of the substrate is superior to the second ink. Adhesion properties of the layer material to the surface of the substrate. Of course, all three conditions can be optimal.

In another embodiment of the present invention, in addition to the above embodiments, the printed film further includes a protective film 5 on the side of the microporous film 3 facing away from the first ink layer 2 to protect the The printing surface of the printed film (i.e., the microporous film 3 and the first ink layer 2) is protected from contamination or the like. Optionally, the material of the protective film 5 is polyethylene terephthalate (PET), and other materials such as polycarbonate, polyvinyl chloride, polydecyl methacrylate. A metal foil or a paper film or the like is provided as long as it can protect the microporous film 3 and the first ink layer 2 from contamination.

It should be noted that the material for forming the protective film 5 may be the same as or different from the material for the support film 1, and the present invention is not limited thereto.

In the solution in which the second ink layer and the protective film are simultaneously disposed, when selecting the material of the second ink layer, it is first considered that the abrasion resistance of the second ink layer material after curing is better than that of the first ink layer material after curing. performance. Secondly, in some cases, taking into account factors such as production costs, the second ink layer material and The adhesion of the surface of the substrate is weaker than that of the first ink layer material and the surface of the substrate, and even the adhesion of the second ink layer material to the surface of the protective film is weaker than that of the first ink layer material and the surface of the protective film.

When printing a pattern by using the printed film provided in the embodiment of the present invention, as shown in FIG. 3, the protective film 5 is first removed, and then the microporous film 3 is separated from the first ink layer 2 Sidely facing the substrate 6, the printed film is placed on a surface of the substrate 6 at a user-defined position, and then the side of the support film 1 facing away from the first ink layer 2 is used by a squeegee 7 or the like. The predetermined pattern of the first ink layer 2 can be printed on the substrate 6 from one side to the other in one direction, which is convenient and quick to use. Alternatively, after the printed film is placed on the surface of the substrate 6, the user can customize the desired substrate on the side of the support film 1 facing away from the first ink layer 2 by using a drawing tool such as a pencil or the like. The printed pattern on the 6 can print the corresponding pattern on the substrate 6 according to the user's preference, thereby improving the arbitrariness and convenience of printing, and satisfying the individualized needs of the users. After printing the pattern onto the substrate, the remaining printed film is removed from the substrate. The printed film provided by the above embodiments of the present invention can be produced separately or attached to the surface of the terminal. Another embodiment of the present invention further provides a terminal having a printed film attached to the surface thereof, the printed film being a printed film not including a protective film provided in any of the above embodiments. Specifically, the surface of the terminal is attached with a microporous film, and the microporous film has a plurality of through holes; a side of the microporous film facing away from the surface of the terminal is adhered with a first ink layer, that is, a side of the first ink layer is tight A microporous film surface is attached; a support film is attached to the other side of the first ink layer. In other embodiments, the second ink layer is further disposed between the first ink layer and the support film of the terminal surface, and the manner of setting the second ink layer and the material selection are as described in the above embodiments, and details are not described herein. . Since the microporous film is directly attached to the surface of the terminal, when printing a pattern, it is only necessary to apply a certain pressure on a side of the supporting film facing away from the first ink layer, so that the first The ink layer is embossed to the surface of the terminal through the through hole of the microporous film, and printing of the printed pattern can be completed on the surface of the terminal. After printing the pattern onto the surface of the terminal, the printed film can be peeled off from the terminal.

As described in the above embodiment, when printing a pattern, the user only needs to draw a pattern on the side of the supporting film facing away from the first ink layer by using a drawing tool such as a pencil, so that the user can like the user on the terminal. Printing the corresponding pattern, the order is fast, and meets the individual needs of the users. For the terminal that has a preset pattern on the printed film before leaving the factory, the user can simply print the preset pattern to the other side by scraping from one side of the support film to the other side by using a common squeegee or the like.
