Description

Three-dimensional plastic sheet with transparent window {Method for manufacturing lenticular plastic sheets}

The present invention relates to a three-dimensional plastic sheet, and more particularly, the semi-circular or hemispherical convex lenses are arranged on the surface of the plastic sheet to view a three-dimensional image, as well as special characters such as barcodes or fine The present invention relates to a three-dimensional plastic sheet configured to allow a character to be recognized by a sensor and to partially display any specific portion of the three-dimensional plastic sheet.

The above-described three-dimensional method has a configuration in which semi-cylindrical or hemispherical lenses having a constant pitch on the front surface of the sheet are continuously formed in an array of regular intervals. I) Record and print the image of the object on one sheet plate, and see the three-dimensional image of the object floating or entering the space when viewed with both eyes from the front of the sheet.

Mainly this method is a three-dimensional method produced by a continuous lens sheet by plastic molding, the sheet is a transparent material, the printing surface calculated according to the arrangement of the lens three-dimensional by human binocular disparity when viewed from the front of the lens This is how it works.

However, these methods have some problems in the commercialization of three-dimensional objects.

First, these three-dimensional fabric sheets are not high resolution like normal printing due to the embossed surface of the lens type, and thus cannot provide clear and clean prints.

In other words, when printing printed material on one side of the stereoscopic single sheet in the printing of fine characterized special characters such as barcodes, a failure occurs that is not recognized by the terminal that recognizes the barcode. This is because the embossed surface is refracted by light.

Secondly, these stereoscopic sheets are formed on the embossed surface formed on one surface of the sheet due to their morphological characteristics, that is, small lenses having a constant bone shape in the lenticular method and small radial convex lenses in the integral method. When viewed from the canal, it is seen as an opaque material due to the refraction of light.

For example, if the box is made of such a three-dimensional sheet, the part to be three-dimensional can be seen by the printing surface expressing the three-dimensional, but in order to make the contents inside the box intentionally visible, it is necessary to cut a portion of the sheet even if it is a transparent material. You have no choice but to produce an incomplete product.

Third, in this three-dimensional plastic sheet, due to the valley shape of the semi-circular or hemispherical convex lens, sometimes a normal sticker or hologram sticker, which is necessary for a product, is very difficult to attach to the front surface of the lens.

Therefore, the present invention provides a manufacturing method of a three-dimensional image sheet that can be mass-produced by combining plastic molding technology and advanced printing technology, and when a product is printed, special characters such as barcodes are printed on these sheets. When reading the printed matter through the sheet, it can be recognized normally, there is no problem in recognizing the fine letters as well, it is easy to attach stickers on the front of the sheet, and the part of the sheet is made transparent. There is this.

The present invention was devised to solve the above problems, and its purpose is not only to display a three-dimensional image by arranging semi-circular or hemispherical convex lenses on the surface of the plastic sheet, but also to display special characters such as barcodes or fine It is to provide a high-quality three-dimensional plastic sheet and a method of manufacturing the same to enable the recognition of the characters in the sensor, to make the three-dimensional plastic sheet partially transparent, and to be able to stereoscopic representation of any specific part.

A feature of the present invention for achieving the above object is made of a transparent synthetic resin, the upper surface is formed in a semi-circular or hemispherical convex lens 11 is formed in an arrangement, the transparent portion of the upper surface of the convex lens 11 A convex lens layer 10 having the ink resin layer 20 formed thereon, or a heat press plane layer 21 processed by a high-pressure compression press on a part of an upper surface of the convex lens 11; The three-dimensional plastic sheet is formed of a transparent synthetic resin plate material having a thickness corresponding to the focal length of the convex lens 11, and the bottom surface thereof is laminated and bonded to the transparent plate 30 having the focal length print layer 40 in turn. It can be achieved by.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

As shown in Fig. 1 or 4, a convex lens layer 10 is formed on the uppermost side of the three-dimensional card 1 according to the present invention, and the convex lens layer 10 is formed by forming a transparent synthetic resin on the upper surface thereof. The semi-circular convex lenses 11 are arranged in an arrangement in which they are spread at regular intervals.

A part of the upper surface of the convex lenses 11 arranged on the upper surface of the convex lens layer 10 is formed with a viewing window made of a transparent ink resin layer 20 or a part of the upper surface of the convex lens 11 with a high-pressure compression press. By processing, a portion of the convex lens 11 is melted in a row to form a flat surface heat press layer 21, so that a small letter printed with a picture can be clearly displayed or a sticker such as a hologram can be attached.

On the bottom of the same position of the transparent ink resin layer 20 or the heat press plane layer 21, a non-focal print surface 41 is formed as a part of the focal length print layer 40, or the non-focus printed surface (41) consists of information, pictures and text relating to the manufacturer. The image of the non-focal print surface 41 belongs to a range that does not exhibit a three-dimensional effect or a special effect, and is composed of special characters such as pictures, characters, or barcodes that represent photorealistic images with vivid image quality.

When printing a special character such as a bar code at the bottom of this area, the effect of the convex lens disappears due to the transparent ink resin layer 20 or the heat press plane layer 21 filled between the convex lenses 11. Since the refraction of light generated from the lens disappears, it is possible to print a fine character that could not be expressed due to the characteristics of the conventional three-dimensional sheet, or to print a special character that can recognize the barcode sensor.

A transparent plate 30 made of a transparent synthetic resin is positioned below the convex lens layer 10, and the thickness of the transparent plate 30 is equal to the focal length of the convex lens 11.

The bottom surface of the transparent plate 30 has the same spacing arrangement as that of the convex lens layer 10, and a three-dimensional printing surface 42 having a calculated graphic shape for expressing a three-dimensional effect is formed on the focal length printing layer 40. It is.

However, in the printing located on the focal length printed layer 40, it is difficult to express the fine print. The reason is that the three-dimensional sheet for expressing the three-dimensional surface of the convex lens 11 and the binocular parallax due to human binocular parallax due to the characteristics of the three-dimensional feeling, the convex lens of the convex lens is always convex lens resolution in the related feeling This is because the density of array spacing of (10) or more cannot be expressed.

That is, no matter how high-resolution printing is printed on the focal length print layer 40 on the bottom surface of the convex lens layer 10, a three-dimensional sheet (for example, can only be seen through the refracted convex lens layer 10 of light). The resolution of 1) can never see more than the arrangement density of the convex lens layer 10.

Therefore, the convex lens layer 10, the transparent ink resin layer 20, or the heat press plane layer 21, the transparent plate 30, and the focal length print layer 40 are stacked in this order to complete the three-dimensional sheet 1. You can do it.

The three-dimensional card 1 having the above-described configuration includes a transparent ink resin layer 20 and a heat press plane layer 21 located on the upper surface of the convex lens layer 10 on a non-focal printing surface 41 through which the visible light can be seen. This makes it possible to clearly see various information or characters and pictures related to the manufacturer. At the same time, the picture printing surface having the same tendency as the convex lens spacing of the three-dimensional sheet, that is, the three-dimensional printing surface 42 of the focal length printing layer 40 is larger than the depth of the transparent plate 30 due to the convex lens effect and binocular parallax. A stereoscopic effect such as a figure or pattern floating deeper or above the surface of the convex lens layer 10 can be obtained in contrast to the non-focus printing surface 41 which can clearly and precisely observe.

Therefore, such stereoscopic expression has the advantage of providing a high-quality stereoscopic card that has both a stereoscopic feeling not seen in a conventional stereoscopic sheet and at the same time, a functionality that can simultaneously carry functions such as a barcode.

Referring to the manufacturing process of the three-dimensional sheet (1) according to the present invention in detail through the embodiment as follows.

The transparent ink resin layer 20 was formed on the upper surface of the convex lens layer 10 after printing with a transparent ink on a part of the upper surface of the convex lens layer 10 composed of a flat synthetic resin. In addition, when the compression processing of a high temperature press on a part of the upper surface of the convex lens layer 10, a hot press plane layer 21 in which the lens shape was flattened was formed on a part of the upper surface of the convex lens layer 10.

Subsequently, the bottom surface of the transparent plate 30 made of transparent synthetic resin was printed and dried to form a focal length print layer 40.

The three-dimensional printing surface 42 of the focal length printing layer 40 is a printing surface having the same alignment interval tendency as that of the convex lens layer 10, and the image printing surface can see a three-dimensional image.

At the same time, barcodes or microprints were performed on the non-focus printing surface 41 of the focal length printing layer 40 located at the same position as the transparent ink resin layer 20 or the heat press plane layer 21, and the sensor recognition was clear. Possible printouts were obtained.

Subsequently, as shown in FIGS. 3A and 3B, a heat press plane layer 21 is formed on the front surface of the box made of a three-dimensional sheet, and a non-focal print surface 41 located on the lower surface thereof has a bar code like a bar code. When printing special characters, clear high-resolution prints were obtained, and the non-focal printing surface 41 was not printed on the lower surface of the transparent ink resin layer 20, and the product contents 50 inside the box were transparently observed. Could.

Subsequently, when the hologram 90 or sticker of the manufacturer was attached to the top surface of the transparent ink resin layer 20 on the surface of the three-dimensional sheet 1 according to the type of the product, firm adhesion was possible.

In addition, the process of attaching the printed matter or the synthetic resin material 60, etc. according to the use of the product at the bottom of the three-dimensional sheet (1) was to be further included, so that the three-dimensional sheet (1) can be used for more various purposes

3A and 3B, the three-dimensional sheet 1 is composed of a semi-circular convex lens 11 of a lenticular method and a hemispherical convex lens 11-1 of an integral method, as shown in FIGS. It can be produced as a three-dimensional sheet (1), and the thickness is not only formed differently depending on the type and use, as the focal length is formed differently depending on the size of the convex lens 11, eventually convex lens layer 10 and transparent Since the thickness of the plate 30 is to be adjusted, the thicknesses of the materials are not accurately indicated.

In the above described and illustrated with respect to the preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment, it is common in the field to which the present invention belongs without departing from the spirit of the present invention claimed in the claims. Various modifications may be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.

As described above, the three-dimensional sheet 1 of the present invention includes the transparent ink resin layer 20 or the hot press plane layer 21 printed on the upper surface of the convex lens layer 10 and the ultra-short distance printing layer seen through the same. Various information printed on the non-focal print surface 41 of 40 can be clearly seen as a character and a picture deviating from the refraction of light of the convex lens 11, and enable sensor-sensitive printing such as a barcode. At the same time, the three-dimensional printing surface 42 of the focal length printing layer 40 has a three-dimensional or convex lens layer 10 such that a figure or a pattern is located deeper than the depth of the transparent plate 30 by the convex lens 11 effect. By the three-dimensional feeling of figures floating on the surface of the surface), not only can the three-dimensional feeling contrasted with the non-focus printing surface 41 appearing clearly, but also the transparent ink resin layer 20 or the heat press plane layer 21 is transparent. As a creative role, the convex lens layer 10 It is formed on the inside to see the transparent, fine letters, etc. can be observed without the refraction of the light of the convex lens 11, to facilitate the workability when attaching the hologram sticker (90), and the variety of designs There is an advantage, such as to provide a high-quality three-dimensional sheet that can meet the purchasing needs of modern consumers seeking.
