Description

Technical Field

[0001] The present application relates to the technical field of identification card manufacturing, and in particular to an identification card and a method for manufacturing the same. Background Art

[0002] The existing identification card body structure is complex, with many layers, including multiple PVC fabric layers. The multiple PVC fabric layers mainly serve as a protective layer for the front and back images and texts. If the card product contains a magnetic stripe, it also serves as a carrier layer for the magnetic stripe. Although the multiple PVC fabric layers can make the front and back images and texts wear-resistant and will not bend or deform, this also leads to a long process flow and high processing costs for the existing card body structure.

[0003] Therefore, the main technical problem to be solved by the present invention is how to solve the wear resistance problem of the front and back graphics and the asymmetric bending problem of the front and back PVC materials on the basis of reducing the PVC fabric layer and simplifying the process flow.

For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; it may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0034] Example 1

[0035] Existing identification cards include magnetic stripe cards and non-magnetic stripe cards.

[0036] like Figure 1 As shown, the existing magnetic stripe identification card includes a front PVC fabric layer, a front graphic layer, a front PVC printed core layer, an intermediate layer, a back PVC printed core layer, a back graphic layer, a back PVC fabric layer, and a magnetic stripe.

[0037] like Figure 2 As shown, the existing non-magnetic stripe identification card includes a front PVC fabric layer, a front graphic layer, a front PVC printed core layer, an intermediate layer, a back PVC printed core layer, a back graphic layer, and a back PVC fabric layer.

[0038] The above two types of card body structures are symmetrical as a whole. The front PVC core layer is symmetrical with the back PVC core layer, and the front PVC fabric layer is symmetrical with the back PVC fabric layer. The purpose of using a symmetrical card body structure is to avoid bending of the identification card body and make the card body more straight.

[0039] The front and back PVC layers are made of transparent PVC material. Their purpose is to protect the front and back images from wear and tear, thereby extending the product's lifespan. The back PVC layer not only protects the images but also serves as a carrier for the magnetic stripe. If the wear resistance issues of the front and back images can be resolved, as well as the asymmetrical bending problem of the front and back PVC materials, the transparent PVC layer can be optimized and eliminated.

[0040] Based on this, the present invention provides an identification card, which also includes a magnetic stripe card and a non-magnetic stripe card.

[0041] like Figure 3 As shown in the figure, the magnetic stripe card is constructed from seven laminated layers. From top to bottom, the card structure includes: front graphic layer ①, front PVC printed core layer ②, middle layer ③, back PVC printed core layer ④, back graphic layer ⑤, back PVC fabric layer ⑥, and magnetic stripe ⑦. Compared to existing magnetic stripe identification cards, this card eliminates one front PVC fabric layer, while back PVC fabric layer ⑥ still serves as the carrier for magnetic stripe ⑦.

[0042] like Figure 4 As shown, the non-magnetic stripe card is constructed from five laminated layers of material. From top to bottom, the card structure includes: front graphic layer ①, front PVC printed core layer ②, middle layer ③, back PVC printed core layer ④, and back graphic layer ⑤. Compared to existing non-magnetic stripe identification cards, this card eliminates two front PVC fabric layers. While the non-magnetic stripe card manufactured using the special manufacturing method of Example 2 below has asymmetrical front and back PVC fabrics, this does not cause the card to bend, and the card protects the graphic from wear and tear without using PVC fabric.

[0043] In the card body structure, the front graphic layer ① is printed on the front PVC printing core layer ② by offset printing or silk screen printing, and the back graphic layer ⑤ is printed on the back PVC printing core layer ④ by offset printing or silk screen printing. The layout of the graphics on the front and back graphic layers can be set according to needs and can also be personalized.

[0044] Since the magnetic stripe identification card provided by the present application has one fewer front PVC fabric layer than the existing identification card, in order to improve the wear resistance of the card, after printing the front graphic layer on the front PVC printing core layer ②, a layer of friction-resistant varnish is printed on the front graphic layer. The thickness of the wear-resistant varnish is preferably 5um. As for the non-magnetic stripe identification card provided by the present application, since it has two fewer PVC fabric layers than the existing identification card, in order to improve the wear resistance of the card, after printing the front graphic layer ① on the front PVC printing core layer ②, a layer of friction-resistant varnish is printed on the front graphic layer ①, and after printing the back graphic layer ⑤ on the back PVC printing core layer ④, a layer of friction-resistant varnish is also printed on the back graphic layer ⑤. The thickness of a layer of wear-resistant varnish is preferably 5um.

[0045] Example 2

[0046] like Figure 5 As shown, the second embodiment of the present invention provides a method for manufacturing an identification card. The second embodiment is a method for manufacturing a magnetic stripe identification card provided in the first embodiment, specifically comprising:

[0047] Step 510: Adjust the Vicat points of the front PVC printing core layer ② and the back PVC printing core layer ④, and set the Vicat point of the front PVC printing core layer ② higher than the Vicat point of the back PVC printing core layer ④.

[0048] The Vicat point is the critical temperature point at which PVC material softens when heated. PVC materials with different Vicat points soften at different rates and generate different amounts of internal stress after cooling.

[0049] This invention utilizes the different internal stresses of the front and back PVC core layers to prevent warping even when the front PVC fabric layer ① and back PVC fabric layer ⑦ are not symmetrical. In this solution, the VI card point of the front printed PVC core layer ② is set higher than the VI card point of the back printed PVC core layer ④, thereby reducing the front PVC fabric layer and preventing the card product from warping.

[0050] Through testing and batch verification, the Vicat point of the front PVC printed core layer ② is preferably 76, while the Vicat point of the back PVC printed core layer ④ is preferably 70.

[0051] Step 520: Prepare the front and back layout images and print them on the front and back PVC printing core layers respectively;

[0052] For example, the front and back images and texts can be printed on the front and back PVC printing core layers by offset printing or silk screen printing.

[0053] Step 530: After the layout image and text are printed on the front PVC printing core layer ②, a layer of friction-resistant varnish is printed on the surface of the layout image and text;

[0054] Friction-resistant varnish is a transparent fluid, preferably acrylic resin. The preferred thickness is 5 μm, which does not affect the clarity of the graphics and text on the layout, and serves as a protective layer for the graphics and text. Friction-resistant varnish and its printing process have been maturely applied to card products, and its wear resistance has been fully verified.

[0055] Step 540: Place the front PVC printed core layer ② printed with friction-resistant varnish at a temperature of 40 to 60 degrees to dry for 5 to 10 minutes.

[0056] Step 550: After the above steps are completed, the front PVC printed core layer ②, the middle layer ③, the back PVC printed core layer ④, the back graphic layer ⑤, the back PVC fabric layer ⑥ and the magnetic strip ⑦ are aligned and laminated together.

[0057] Specifically, after the front PVC printed core layer ②, the middle layer ③, the back PVC printed core layer ④, the back graphic layer ⑤, the back PVC fabric layer ⑥ and the magnetic stripe ⑦ are aligned, the layers are composited together by ultrasonic or heating. At this point, the card production process is basically completed and the card body structure no longer requires the front PVC fabric layer.

[0058] Furthermore, based on the desired card surface effect, an appropriate laminated steel plate is selected, and the composite semi-finished card body is placed in a hot press at a temperature of 130-150 degrees Celsius and a pressure of 50-120 N. In the card body structure described in step 5), the back PVC fabric layer and the front PVC printed core layer printed with friction-resistant varnish serve as the outermost layers of the card body and are in direct contact with the steel plate.

[0059] After completing the hot pressing treatment, the card body is placed under low temperature conditions for cold pressing for 15 to 20 minutes. The temperature of the cold pressing stage is 10 to 15 degrees, and the cold pressing pressure is 100 to 150N.

[0060] If the card body structure is pre-made to the required card size, an identification card will be obtained after the above operation is completed. If the card body structure is a multi-plate card body, the multi-plate card body will be punched into a single small card by a die. The size of the identification card can be personalized according to the needs. For example, the size of a single small card is 85.6mm*53.98mm.

[0061] Example 3

[0062] like Figure 6 As shown, the third embodiment of the present invention provides a method for manufacturing an identification card. The third embodiment is a method for manufacturing a non-magnetic stripe identification card provided in the first embodiment, specifically comprising:

[0063] Step 610: Prepare the front and back layout images and print them on the front and back PVC printing core layers respectively;

[0064] For example, the front and back images and text can be printed on the front and back PVC printed core layers using offset printing or silk screen printing. Since the front and back PVC fabric layers can be omitted in the non-magnetic stripe card provided in this embodiment, it is not necessary to set different VI card points like the magnetic stripe card in Example 2. Preferably, the VI card point of the front and back PVC printed core layers is set to the same value of 70 in this embodiment.

[0065] Step 630: After the layout images are printed on the front and back PVC printing core layers, a layer of friction-resistant varnish is printed on the front and back surfaces of the layout images respectively;

[0066] Friction-resistant varnish is a transparent fluid, preferably acrylic resin. The preferred thickness is 5 μm, which does not affect the clarity of the graphics and text on the layout, and serves as a protective layer for the graphics and text. Friction-resistant varnish and its printing process have been maturely applied to card products, and its wear resistance has been fully verified.

[0067] Step 640: Place both the front and back PVC printed core layers printed with friction-resistant varnish at a temperature of 40 to 60 degrees to dry for 5 to 10 minutes.

[0068] Step 650: After the above steps are completed, the front PVC printed core layer ②, the middle layer ③, the back PVC printed core layer ④, and the back graphic layer ⑤ are aligned and laminated together.

[0069] Specifically, after the front PVC printed core layer ②, the middle layer ③, the back PVC printed core layer ④, the back graphic layer ⑤, the back PVC fabric layer ⑥ and the magnetic stripe ⑦ are aligned, the layers are composited together by ultrasonic or heating. At this point, the card production process is basically completed, and the card body structure no longer requires the front PVC fabric layer and the back PVC fabric layer.

[0070] Furthermore, based on the desired card surface effect, an appropriate double-sided laminated steel plate is selected, and the composite semi-finished card body is placed in a hot press at a temperature of 130-150 degrees Celsius and a pressure of 50-120 N. In the card body structure described in step 5), both the front and back PVC printed core layers, printed with friction-resistant varnish, are in direct contact with the steel plate.

[0071] After completing the hot pressing treatment, the card body is placed under low temperature conditions for cold pressing for 15 to 20 minutes. The temperature of the cold pressing stage is 10 to 15 degrees, and the cold pressing pressure is 100 to 150N.

[0072] If the card body structure is pre-made to the required card size, an identification card will be obtained after the above operation is completed. If the card body structure is a multi-plate card body, the multi-plate card body will be punched into a single small card by a die. The size of the identification card can be personalized according to the needs. For example, the size of a single small card is 85.6mm*53.98mm.
