Description

Technical Field

[0001] The present invention relates to the technical field of ID card covers, and particularly to an optically printed ID card cover with a leather-like effect and a manufacturing method thereof. Background Art

[0002] Currently, there are basically two types of ID card covers in the industry: those directly hot-stamped with text or patterns using leather-like materials or genuine leather materials. The disadvantage of this type of ID card cover is limited by the hot stamping process and cannot have patterns with multiple colors and light and dark variations. Or, processes such as heat transfer and lamination are implemented on leather-like materials or genuine leather materials to transfer the patterns. The disadvantage of this type of ID card cover is that the patterns are not scratch-resistant. Moreover, the hot-stamped or transferred patterns formed on the ID card covers made by the above two methods are all on the surface, and after long-term contact with air and oxidation or external forces, the patterns will be damaged.

[0034] In a third aspect, an optical printed card sleeve with a leather-like effect comprises: an outer cover sheet, a first inner cover sheet and a second inner cover sheet. The outer cover sheet is provided with a folding line and the outer cover sheet is folded along the folding line. The first inner cover sheet and the second inner cover sheet are arranged on the inner side of the outer cover sheet and are respectively located on both sides of the folding line. The edge of the outer cover sheet is connected to the outer peripheral edge of the first inner cover sheet and the outer peripheral edge of the second inner cover sheet. The outer cover sheet sequentially comprises a first optical film layer and a combined middle grid from outside to inside. The combined middle grid sequentially comprises a cushion layer, a cardboard layer and a PU layer from outside to inside. The first inner cover sheet sequentially comprises a second optical film layer and a shielding layer from outside to inside. The second inner cover sheet sequentially comprises a third optical film layer with a hollowed-out border and a transparent window layer from outside to inside. The structures of the first optical film layer, the second optical film layer and the third optical film layer are the same. The first optical film layer sequentially comprises an optical outer texture, a transparent substrate, a printing layer, an optical inner texture, an electroplated reflective layer and an electroplated protective layer from outside to inside.

[0035] For an optical printed card sleeve with a leather-like effect and a manufacturing method thereof described in the present invention, the beneficial effects are as follows:

[0036] In the manufacturing method of the optical printed card sleeve with a leather-like effect of the present invention, a printing layer with a preset pattern, color or positioning mark is printed on the inner side of the transparent substrate with transparent or semi-transparent ink, and then an optical inner texture is made on the inner side of the printing layer according to the pattern, color or positioning mark of the printing layer, and an optical outer texture is made on the outer side of the transparent substrate, so that an optical inner texture and an optical outer texture with leathery pattern colors, optical anti-counterfeiting and various optical artistic effect decorations can be transferred according to the preset pattern, color or positioning mark, making the card sleeve have multiple colors and light and dark changes and become more gorgeous. The optical outer texture also has a leathery feel. Moreover, since the optical inner texture is arranged on the inner side of the transparent substrate, the pattern is not easily scratched like in the traditional hot stamping process, and air oxidation is avoided, making the service life of the product the same as that of the base material.

[0037] After that, electroplating treatment is carried out on the inner side of the optical inner texture to obtain an electroplated reflective layer, and ink printing is carried out on the inner side of the electroplated reflective layer to obtain an electroplated protective layer. The electroplated reflective layer has special metal reflectivity. By combining the electroplated reflective layer with the optical inner texture, the problem that the thermal transfer process cannot make patterns with multiple colors and light and dark changes is solved. The electroplated reflective layer can provide sufficient reflected light for the optical inner texture, making the optical inner texture more gorgeous. And an electroplated protective layer is arranged on the inner side of the electroplated reflective layer to avoid the electroplated reflective layer being oxidized and affecting the luster.

[0038] Afterwards, the optical film is cut to obtain a first optical film layer, a second optical film layer, and a third optical film layer. An outer cover sheet is formed by sequentially stacking and laminating a cushion layer, a cardboard layer, and a PU layer on the inner side of the first optical film layer. The cushion layer further enhances the hand feeling, and the cardboard layer can play a supporting role to prevent the ID card holder from being easily bent. The second optical film layer is laminated on the inner side of the shielding layer to form a first inner cover sheet, and the third optical film is sewn and laminated on the inner side of the transparent window layer to form a second inner cover sheet. The first inner cover sheet and the second inner cover sheet are stacked and positioned on the inner side of the outer cover sheet and on both sides of the folding line. The outer peripheries of the stacked and positioned outer cover sheet, the first inner cover sheet, and the second inner cover sheet are sealed. By sealing the first inner cover sheet with the shielding layer and the outer cover sheet, a card cavity that can effectively isolate the card signal can be formed. When the ID card holder is closed, the chip signal cannot be read, and when the ID card holder is opened, the card data can be read and edited in the card cavity. By sealing the second inner cover sheet with the transparent window layer and the outer cover sheet, a card cavity that can directly view the card information can be formed. At the same time, the second optical film layer of the first inner cover sheet and the third optical film layer with a hollow border of the second inner cover sheet can ensure that the inner side and the outer side of the ID card holder have the same color texture and hand feeling when the ID card holder is opened.

[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment

[0049] As Figures 1 to 4 and Figure 6 shown, the present invention discloses a manufacturing method of an optical printed ID card sleeve with a leather-like effect, including the following steps:

[0050] (1) Printing a printing layer 113 with preset patterns, colors, and positioning marks on the inner side of the transparent substrate 112 with ink;

[0051] (2) Making an optical inner texture 114 on the inner side of the printing layer 113 and making an optical outer texture 111 on the outer side of the transparent substrate 112 according to the patterns, colors, and positioning marks of the printing layer 113;

[0052] (3) Performing electroplating treatment on the inner side of the optical inner texture 114 to obtain an electroplated reflective layer 115;

[0053] (4) Performing ink printing on the inner side of the electroplated reflective layer 115 to obtain an electroplated protective layer 116, thereby completing the production of the optical film;

[0054] (5) Cutting the optical film to obtain a first optical film layer 11, a second optical film layer 21, and a third optical film layer 31, wherein the third optical film layer 31 is a hollow frame structure;

[0055] (6) Stacking and laminating a liner layer 121, a cardboard layer 122, and a PU layer 123 in sequence on the inner side of the first optical film layer 11 to form an outer cover sheet 1, wherein the outer cover sheet 1 is provided with a folding line 10;

[0056] (7) Bonding the second optical film layer 21 to the inner side of the shielding layer 22 to form a first inner cover sheet 2, and bonding and sewing the third optical film to the inner side of the transparent window layer 32 to form a second inner cover sheet 3;

[0057] (8) Stacking and positioning the first inner cover sheet 2 and the second inner cover sheet 3 on the inner side of the outer cover sheet 1 and on both sides of the folding line 10;

[0058] (9) The outer peripheries of the stacked and positioned outer cover sheet 1, the first inner cover sheet 2 and the second inner cover sheet 3 are sealed to obtain an optically printed card holder with a leather-like effect.

[0059] The manufacturing method of the optically printed card sleeve with imitation leather effect comprises the following steps: printing a printing layer 113 with a preset pattern, color or positioning mark on the inner side of a transparent substrate 112 with transparent or translucent ink, and then making an optical inner texture 114 on the inner side of the printing layer 113 according to the pattern, color or positioning mark of the printing layer 113, and making an optical outer texture 111 on the outer side of the transparent substrate 112, so that the optical inner texture 114 and the optical outer texture 111 with leather pattern color and optical anti-counterfeiting and various optical art effects can be transferred according to the preset pattern, color or positioning mark, wherein the optical outer texture 111 also has a leather feel, so that the card sleeve can have a variety of colors and light and dark changes, becoming more gorgeous, and because the optical inner texture 114 is arranged on the inner side of the transparent substrate 112, it will not be easily scraped off like the pattern in the traditional hot stamping process, and air oxidation is avoided, so that the life of the product is synchronized with the substrate.

[0060] Afterwards, electroplating is performed on the inner side of the optical inner texture 114 to obtain an electroplated reflective layer 115, and ink printing is performed on the inner side of the electroplated reflective layer 115 to obtain an electroplated protective layer 116. The electroplated reflective layer 115 has special metallic reflection. The cooperation between the electroplated reflective layer 115 and the optical inner texture 114 solves the problem that the thermal transfer process cannot produce patterns with multiple colors and light and dark changes. The electroplated reflective layer 115 can provide sufficient reflected light for the optical inner texture 114, making the optical inner texture 114 more colorful, and the electroplated protective layer 116 is arranged on the inner side of the electroplated protective layer 116 to prevent the electroplated reflective layer 115 from being oxidized and affecting the gloss.

[0061] Afterwards, the optical film is cut to obtain a first optical film layer 11, a second optical film layer 21, and a third optical film layer 31. An outer cover sheet 1 is formed by sequentially stacking and laminating a cushion layer 121, a cardboard layer 122, and a PU layer 123 on the inner side of the first optical film layer 11. The cushion layer 121 further improves the hand feeling, and the cardboard layer 122 can play a supporting role to prevent the ID card holder from being easily bent. The second optical film layer 21 is laminated on the inner side of the shielding layer 22 to form a first inner cover sheet 2, and the third optical film is sewn and laminated on the inner side of the transparent window layer 32 to form a second inner cover sheet 3. The first inner cover sheet 2 and the second inner cover sheet 3 are stacked and positioned on the inner side of the outer cover sheet 1 and on both sides of the folding line 10. The outer peripheral edges of the stacked and positioned outer cover sheet 1, the first inner cover sheet 2, and the second inner cover sheet 3 are sealed. By sealing the first inner cover sheet 2 with the shielding layer 22 and the outer cover sheet 1, an effective card cavity for isolating the card signal can be formed. When the ID card holder is closed, the chip signal cannot be read, and when the ID card holder is opened, the card data can be read and edited. By sealing the second inner cover sheet 3 with the transparent window layer 32 and the outer cover sheet 1, a card cavity for directly visualizing the card information can be formed. At the same time, the second optical film layer 21 of the first inner cover sheet 2 and the third optical film layer 31 with a hollow border of the second inner cover sheet 3 can ensure that the inner side and the outer side of the ID card holder have the same color texture and hand feeling when the ID card holder is opened.

[0062] It should be noted that the ink can be transparent or semi-transparent, and the ink has a variety of colors, so as to increase different display effects. The sealing methods include sewing or high-frequency hot pressing. After sewing, the edges are polished, edge oiled, and positioned and bent to make the edges of the ID card holder smooth.

[0063] Preferably, the following steps are further included:

[0064] ⑽ The edges of the optically printed ID card holder with a leather-like effect after production are further edge oiled. When the optically printed ID card holder is not edge oiled, the edges of each layer will form loose openings at the edges of the optically printed ID card holder, resulting in rough edges of the optically printed ID card holder, which affects the hand feeling and is prone to wear of the edges of the optically printed ID card holder. Edge oiling the edges of the optically printed ID card holder can make the edges of each layer composite, making the edges of the optically printed ID card holder round and soft, and improving the hand feeling and wear resistance of the edges of the optically printed ID card holder.

[0065] Preferably, before step (1), the transparent substrate 112 is processed by coating a primer layer for enhancing adhesion on the inner and outer sides of the transparent substrate 112. Since the adhesion of some transparent substrates 112 is insufficient, such as ordinary TPU, by coating a primer layer on the inner and outer sides of the transparent substrate 112, the adhesion of the transparent substrate 112 can be strengthened, so that the printing layer 113, the optical inner texture 114 and the optical outer texture 111 can better adhere to the transparent substrate 112, thereby prolonging the service life of the ID card sleeve. Preferably, the primer layer can be coated with polyamide, and the coating method can be coating and printing.

[0066] Preferably, in step (1), the transparent substrate 112 is made of modified TPU with a hardness of 80-90 N / mm 2 and the thickness of the transparent substrate 112 is 0.1-0.3 mm; in step (1), when the transparent substrate 112 is a roll material, rotary offset printing, gravure printing, digital printing or flexographic printing is alternatively or combinatorially used for the transparent substrate 112; when the transparent substrate 112 is a single-sheet material, single-sheet offset printing, digital printing, relief printing is alternatively or combinatorially used for the transparent substrate 112.

[0067] Preferably, in step (2), when the transparent substrate 112 is a roll material, the optical inner texture 114 and the optical outer texture 111 are transferred by a winding type positioning texture transfer machine and cured by an LED light source; when the transparent substrate 112 is a single-sheet material, a single-sheet texture machine is used for positioning the transfer of the optical inner texture 114 and the optical outer texture 111 and cured by an ultraviolet drying tunnel furnace; wherein, the single-sheet texture machine positioning includes punching positioning or manual operation positioning.

[0068] It should be noted that for the production of the optical inner texture 114 and the optical outer texture 111, in addition to using the above-mentioned winding type positioning texture transfer machine or single-sheet texture machine to transfer the UV glue, a hot pressing method can also be used.

[0069] Preferably, in step (3), when the transparent substrate 112 is a roll material, winding type vacuum plating is used for electroplating; when the transparent substrate 112 is a single-sheet material, hanging plating is used; the electroplating treatment methods include evaporation plating, electron gun plating, and magnetron sputtering plating.

[0070] Preferably, in step (6), the cushion layer 121 is formed by cutting EVA sponge or pearl cotton, and the cardboard layer 122 is formed by cutting cardboard with a thickness of 0.6-1.2 mm. When using EVA sponge or pearl cotton as the cushion layer 121, the overall weight of the card holder can be reduced. At the same time, EVA sponge and pearl cotton have good buffering effects, which can avoid external force damage to the cards in the card holder. In addition, EVA sponge and pearl cotton have good hand feelings. The cardboard layer 122 is selected with a thickness of 0.6-1.2 mm, which can not only ensure that the thickness of the card holder is not too thick, but also play a good supporting role for the card holder, avoiding the card holder from being easily bent under the action of external force, thereby protecting the cards in the card holder.

[0071] Preferably, in step (7), the shielding layer 22 is selected as an electrostatic shielding sheet with a thickness of 0.1-0.7 mm, and the material of the transparent window layer 32 includes TPU, PET, and PC. The electrostatic shielding sheet can effectively isolate the card signal. When the card holder is closed, the chip signal cannot be read, and when the card holder is opened, the card data can be read and edited. At the same time, it can also avoid the magnetic field interaction between two cards in the card holder.

[0072] As Figures 2 to 4 and Figure 6 shown, the present invention also provides an optical printed card holder with a leather-like effect, including: an outer cover sheet 1, a first inner cover sheet 2 and a second inner cover sheet 3. The outer cover sheet 1 is provided with a folding line 10 and the outer cover sheet 1 is folded along the folding line 10; the first inner cover sheet 2 and the second inner cover sheet 3 are arranged inside the outer cover sheet 1 and are respectively located on both sides of the folding line 10. The edge of the outer cover sheet 1 is connected to the outer peripheral edge of the first inner cover sheet 2 and the outer peripheral edge of the second inner cover sheet 3; the outer cover sheet 1 sequentially includes a first optical film layer 11 and a combined middle grid 12 from outside to inside. The combined middle grid 12 sequentially includes a cushion layer 121, a cardboard layer 122 and a PU layer 123 from outside to inside; the first inner cover sheet 2 sequentially includes a second optical film layer 21 and a shielding layer 22 from outside to inside; the second inner cover sheet 3 sequentially includes a third optical film layer 31 with a hollowed-out border and a transparent window layer 32 from outside to inside; the structures of the first optical film layer 11, the second optical film layer 21 and the third optical film layer 31 are the same. The first optical film layer 11 sequentially includes an optical outer texture 111, a transparent substrate 112, a printing layer 113, an optical inner texture 114, an electroplated reflective layer 115 and an electroplated protective layer 116 from outside to inside.

[0073] Since the outer cover sheet 1, the first inner cover sheet 2 and the outer side of the second inner cover sheet 3 of the ID card sleeve are respectively provided with the first optical film layer 11, the second optical film layer 21 and the third optical film layer 31 with the same structure, and the first optical film layer 11 includes an optical outer texture 111, a transparent substrate 112, a printing layer 113, an optical inner texture 114, an electroplated reflective layer 115 and an electroplated protective layer 116 from the outside to the inside. Since the optical inner texture 114 in the ID card sleeve is arranged inside the optical outer texture 111 and the transparent substrate 112, it will not be exposed to the outside like the existing ID card sleeves. Therefore, it can avoid the pattern blur and shedding caused by the scraping of external forces, and can also avoid the oxidation of the pattern. At the same time, various colors and light and dark changing optical textures can be made through the optical inner texture 114 and the optical outer texture 111, and combined with the reflection of the electroplated reflective layer 115, so that the pattern texture is more colorful. Moreover, the cushion layer 121 of the outer cover sheet 1 can provide good buffering for the ID card sleeve, reducing the damage of external forces to the cards in the ID card sleeve. The cardboard layer 122 can support the ID card sleeve, so that the ID card sleeve will not be easily bent by external forces. In addition, the shielding layer 22 of the first inner cover sheet 2 can effectively isolate the card signal. When the ID card sleeve is closed, the chip signal cannot be read, and the card data can be read and edited only when the ID card sleeve is opened. The transparent window layer 32 of the second inner cover sheet 3 can understand the information recorded on the card surface without taking out the card after opening the ID card sleeve. Embodiment

[0084] ⑽ The outer peripheries of the stacked and positioned outer cover sheet 1, the first inner cover sheet 2 and the second inner cover sheet 3 are sealed to obtain an optically printed card holder with a leather-like effect.

[0085] The manufacturing method of the optically printed card sleeve with imitation leather effect comprises the following steps: printing a printing layer 113 with a preset pattern, color or positioning mark on the inner side of a transparent substrate 112 with transparent or translucent ink, and then making an optical inner texture 114 on the inner side of the printing layer 113 according to the pattern, color or positioning mark of the printing layer 113, and making an optical outer texture 111 on the outer side of the transparent substrate 112, so that the optical inner texture 114 and the optical outer texture 111 with leather pattern color and optical anti-counterfeiting and various optical art effects can be transferred according to the preset pattern, color or positioning mark, wherein the optical outer texture 111 also has a leather feel, so that the card sleeve can have a variety of colors and light and dark changes, becoming more gorgeous, and because the optical inner texture 114 is arranged on the inner side of the transparent substrate 112, it will not be easily scraped off like the pattern in the traditional hot stamping process, and air oxidation is avoided, so that the life of the product is synchronized with the substrate.

[0086] Afterwards, electroplating is performed on the inner side of the optical inner texture 114 to obtain an electroplated reflective layer 115, and ink printing is performed on the inner side of the electroplated reflective layer 115 to obtain an electroplated protective layer 116. The electroplated reflective layer 115 has special metallic reflection. The cooperation between the electroplated reflective layer 115 and the optical inner texture 114 solves the problem that the thermal transfer process cannot produce patterns with multiple colors and light and dark changes. The electroplated reflective layer 115 can provide sufficient reflected light for the optical inner texture 114, making the optical inner texture 114 more colorful, and the electroplated protective layer 116 is arranged on the inner side of the electroplated protective layer 116 to prevent the electroplated reflective layer 115 from being oxidized and affecting the gloss.

[0087] Afterwards, the optical film is cut to obtain a first optical film layer 11, a second optical film layer 21, and a third optical film layer 31. An outer cover sheet 1 is formed by sequentially stacking and laminating a cushion layer 121, a cardboard layer 122, and a PU layer 123 on the inner side of the first optical film layer 11. The feel is further improved by the cushion layer 121, and the cardboard layer 122 can play a supporting role to prevent the ID card sleeve from being easily bent. The second optical film layer 21 is laminated on the inner side of the shielding layer 22 to form a first inner cover sheet 2, and the third optical film is sewn and laminated on the inner side of the transparent window layer 32 to form a second inner cover sheet 3. The first inner cover sheet 2 and the second inner cover sheet 3 are stacked and positioned on the inner side of the outer cover sheet 1 and on both sides of the folding line 10. The outer peripheral edges of the stacked and positioned outer cover sheet 1, the first inner cover sheet 2, and the second inner cover sheet 3 are sealed. By sealing the first inner cover sheet 2 with the shielding layer 22 and the outer cover sheet 1, a card cavity that can effectively isolate the card signal can be formed. When the card sleeve is closed, the chip signal cannot be read, and when the card sleeve is opened, the card data can be read and edited. By sealing the second inner cover sheet 3 with the transparent window layer 32 and the outer cover sheet 1, a card cavity that can directly view the card information can be formed. At the same time, the second optical film layer 21 of the first inner cover sheet 2 and the third optical film layer 31 with a hollow border of the second inner cover sheet 3 can ensure that the inner side and the outer side of the ID card sleeve have the same color texture and feel when the ID card sleeve is opened.

[0088] In addition, since the manufacturing method of this embodiment is to perform processes such as printing, optical transfer, and electroplating on PET or PC, and then composite the processed PET or PC to a transparent substrate (TPU), an optical film that will not deform and has good quality can be obtained.

[0089] Preferably, before step (1), the transparent substrate 112 is processed, and the processing method is: a primer layer for enhancing adhesion is coated on the inner and outer sides of the transparent substrate 112. Since the adhesion of some transparent substrates 112 is insufficient, such as TPU, by coating a primer layer on the inner and outer sides of the transparent substrate 112, the adhesion of the transparent substrate 112 can be strengthened, so that the printing layer 113, the optical inner texture 114, and the optical outer texture 111 can better adhere to the transparent substrate 112, thereby extending the service life of the ID card sleeve. Preferably, the primer layer can be coated with polyamide, and the coating method can be coating and printing.

[0090] Preferably, in step (7), the cushion layer 121 is composed of EVA sponge or pearl cotton, and the thickness of the cardboard layer 122 is 0.6 - 1.2 mm. When using EVA sponge or pearl cotton as the cushion layer 121, it can reduce the overall weight of the ID card holder. At the same time, EVA sponge and pearl cotton have good buffering effects, which can avoid external force damage to the cards in the ID card holder. In addition, EVA sponge and pearl cotton have good handfeel. Meanwhile, the cardboard layer 122 with a thickness of 0.6 - 1.2 mm is selected. While ensuring that the thickness of the ID card holder is not too thick, it can also play a good supporting role for the ID card holder, preventing the ID card holder from being easily bent under external force, thereby protecting the cards in the ID card holder.

[0091] Preferably, in step (8), the shielding layer 22 is a static shielding sheet with a thickness of 0.1 - 0.7 mm, and the material of the transparent window layer 32 includes TPU, PET, and PC. The static shielding sheet can effectively isolate the card signal. When the ID card holder is closed, the chip signal cannot be read, and when the ID card holder is opened, the card data can be read and edited. At the same time, it can also prevent the magnetic fields between two cards in the ID card holder from affecting each other.

[0092] As Figures 2 to 4 and Figure 7 shown, the present invention also provides an optically printed ID card holder with a leather-like effect, including: an outer cover sheet 1, a first inner cover sheet 2, and a second inner cover sheet 3. The outer cover sheet 1 is provided with a folding line 10 and the outer cover sheet 1 is folded along the folding line 10; the first inner cover sheet 2 and the second inner cover sheet 3 are arranged inside the outer cover sheet 1 and are respectively located on both sides of the folding line 10. The edge of the outer cover sheet 1 is connected to the outer peripheral edge of the first inner cover sheet 2 and the outer peripheral edge of the second inner cover sheet 3; the outer cover sheet 1 sequentially includes a first optical film layer 11 and a combined middle grid 12 from outside to inside, and the combined middle grid 12 sequentially includes a cushion layer 121, a cardboard layer 122, and a PU layer 123 from outside to inside; the first inner cover sheet 2 sequentially includes a second optical film layer 21 and a shielding layer 22 from outside to inside; the second inner cover sheet 3 sequentially includes a third optical film layer 31 with a hollowed-out border and a transparent window layer 32 from outside to inside; the structures of the first optical film layer 11, the second optical film layer 21, and the third optical film layer 31 are the same. The first optical film layer 11 sequentially includes an optical outer texture 111, PET (or PC) 117, a printing layer 113, an optical inner texture 114, an electroplated reflective layer 115, an electroplated protective layer 116, and a transparent substrate 112 from outside to inside.

[0093] The above are only preferred embodiments of the present invention, and do not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
