Description

Technical Field

[0001] The present invention relates to the technical field of color card production, and in particular to an anti-glare color card structure and a color card production process. Background Art

[0002] Color cards, also often referred to as colored cards, are printed materials widely used in various occasions. They are usually made of high-quality paper, plastic or other composite materials, and through professional printing technology, rich and colorful designs and information displays are realized.

[0003] The anti-counterfeiting measures on traditional cards often rely on simple watermarks, barcodes or two-dimensional codes, etc., which are easy to be copied and forged.

[0004] In addition, traditional card mechanical cutting equipment relies on physical cutting tools, which are prone to cutting errors due to tool wear or inaccurate mechanical movement, resulting in inconsistent finished product sizes, rough edges or even burrs. These problems not only affect the appearance quality of the cards, but also increase the cost of subsequent processing. And due to the low precision of traditional mechanical cutting equipment, in order to ensure the qualified rate of the final product, a large margin usually needs to be reserved for secondary trimming, which leads to a large amount of waste and material waste, increases the production cost, and also requires further processing and improvement of the color card structure and process, increasing the processes and reducing the work efficiency. For this reason, the inventor of the present invention has proposed an anti-glare color card structure and a color card production process to solve the above-mentioned technical problems. Summary of the Invention

[0005] The invention aims to provide a technical solution to overcome the above deficiencies.

[0006] An anti-glare color card structure includes:

[0007] (a) Substrate layer: composed of one or more combinations of PVC, PET or composite paper materials;

[0008] When using PVC (polyvinyl chloride), the PVC material has high tear strength and is suitable for cards that need to be used for a long time, such as membership cards and coupons. Moreover, PVC has good chemical corrosion resistance and is not easily affected by daily chemicals, suitable for use in a variety of environments. In addition, PVC is a thermoplastic plastic that can be formed by heating and cooling, facilitating cutting, polishing and other post-processing processes, suitable for high-resolution printing, and capable of presenting bright colors and clear text patterns;

[0009] When using PET (polyethylene terephthalate), PET has recyclability, conforms to the concept of green production, helps reduce environmental pollution, releases fewer harmful substances during production and use, has high mechanical strength and rigidity, can withstand large external forces without being easily deformed, and also has good transparency, being suitable for application scenarios requiring a transparent effect, such as transparent business cards or display cards;

[0010] When using composite paper materials, the composite paper materials have a unique natural texture, comfortable to the touch, giving a high-class feeling, suitable for high-end product design. The composite paper can be combined with other materials, such as metal foils and plastic films, to create a variety of visual and tactile effects, enhancing the attractiveness of the product. It is suitable for various printing technologies, including offset printing, screen printing, and digital printing, enabling highly customized designs. Also, compared with plastic materials, the cost of composite paper is lower, suitable for mass production while maintaining a high-quality appearance and feel;

[0011] By combining two or more of PVC, PET, and composite paper materials, the advantages of each material can be fully utilized and their respective deficiencies can be made up for. The combination of the durability of PVC and the transparency of PET can produce cards that are both strong and beautiful. The combination of different materials enables color cards to meet a wider range of application requirements. The combination of composite paper and PVC can produce membership cards with both high-class texture and good durability;

[0012] (b) Reflective layer: Located above the substrate layer, the reflective layer uses a reflective film or a coating containing reflective particles, which can reflect light to produce a reflective effect;

[0013] The reflective layer can reflect light, presenting different gloss and color changes at different angles, enhancing the visual impact and attractiveness of the card, thereby improving brand recognition. The reflective film uses a holographic film or a reflective film with a microprism structure, and this structure can be used for anti-counterfeiting marks to increase the security of the card

[0014] (c) Printing layer: Covering the reflective layer, the printing layer contains graphic and text information, which is achieved through screen printing, offset printing, or digital printing technology;

[0015] (d) Protective layer: Located above the printing layer, the protective layer is used to protect the printing layer from abrasion and contamination. The protective layer uses one of a transparent plastic film or UV varnish;

[0016] Using a transparent plastic film or UV varnish has good abrasion resistance, which can effectively prevent the printed layer from being scratched or worn during daily use, extending the service life of the card. This material has good weather resistance and can remain stable in various environments, not easily affected by factors such as temperature and humidity. In addition, the protective layer can effectively prevent dust, stains and other pollutants from adhering to the printed layer, keeping the card clean and beautiful. The UV varnish can not only provide protection but also increase the gloss of the card surface, making the card look more upscale. Whether choosing a transparent plastic film or UV varnish, it can be combined with the substrate and the reflective layer to ensure the stability of the overall structure.

[0017] Further, the reflective layer is a holographic film or a reflective film with a microprism structure, which can produce different color change effects at different angles;

[0018] Using a holographic film or a reflective film with a microprism structure can present a variety of color changes according to different viewing angles, making the card show a unique visual effect at different perspectives. This dynamic color change effect enhances the visual attraction of the card, thus enhancing the brand image and helping to improve the brand recognition and memory points. Moreover, the holographic film or the reflective film with a microprism structure is not only suitable for indoor environments but also can provide good visibility outdoors or in low-light conditions, and is suitable for cards such as transportation cards and parking cards that need to be used in various environments.

[0019] Further, the thickness of the substrate layer is between 0.2 mm and 0.5 mm, ensuring the flexibility and durability of the card;

[0020] Selecting a thickness range of 0.2 mm to 0.5 mm makes the card have appropriate flexibility and can be bent to a certain extent without damage. This characteristic is suitable for cards used in daily life, such as membership cards, coupons or business cards, which is convenient for users to carry and use. Moreover, using a substrate layer of 0.2 mm can better adapt to bending and folding under various environmental conditions, reducing the risk of fracture caused by excessive rigidity. The materials within this thickness range have sufficient strength to resist wear and tear during daily use. When combined with the protective layer, it can further improve the overall durability of the card, enabling the substrate layer to maintain good dimensional stability and not easily affected by temperature and humidity changes, thus reducing the risk of deformation.

[0021] Further, the thickness of the reflective layer is between 0.01 mm and 0.05 mm, ensuring sufficient reflective effect without affecting the overall thickness of the card;

[0022] Using this range of values can ensure sufficient reflective effect of the reflective layer. Among the thickness of 0.01 mm, the holographic film or the reflective film with micro - prism structure can still provide efficient, bright and uniform reflective effect, enabling the card to show obvious visual changes at different angles. Within this thickness range, the reflective layer can achieve holographic patterns and multi - level color change effects, enhancing the design flexibility and visual diversity of the card. Moreover, the reflective layer is also applicable to anti - counterfeiting applications. The complex holographic patterns are difficult to copy, providing additional security. When the reflective layer is combined with the substrate layer, printing layer and protective layer, it forms an integral structure, avoiding unevenness or delamination problems caused by excessive thickness.

[0023] A color card production process for manufacturing a reflective color card structure, comprising the following steps:

[0024] (a) Preparation stage: Select substrate materials that meet the specifications;

[0025] (b) Cutting stage: Use high - precision cutting equipment to cut the substrate to form a substrate sheet with a predetermined shape and size;

[0026] (c) Coating the reflective layer: Uniformly coat a reflective film or a coating containing reflective particles on the substrate sheet;

[0027] (d) Printing graphics and text: Perform graphics and text printing on the reflective layer to form a printing layer;

[0028] (e) Laminating or coating the protective layer: Cover a transparent plastic film or coat UV varnish on the surface of the printing layer as a protective layer;

[0029] (f) Cutting the finished product: Use a numerical control cutting device to finely cut the processed card to ensure smooth edges without burrs;

[0030] (g) Quality inspection: Conduct an appearance inspection on the completed reflective color card to ensure no obvious defects or flaws.

[0031] Furthermore, in the cutting stage (b), the high - precision cutting equipment is equipped with an automatic pressure - regulating system to ensure that the surface of the material is not damaged during the cutting process;

[0032] This stage is operated using a computer numerical control (CNC) machine. The laser head is controlled by a computer to move along a preset path to achieve precise cutting. Through programming, continuous and efficient batch production is realized, reducing manual intervention, expanding the design possibilities of the product, and the cutting path and parameters can be adjusted according to different design requirements to meet personalized customization needs.

[0033] The following are the specific steps of the cutting stage:

[0034] ① Place the selected base material flat on the workbench, and ensure that there are no impurities such as dust and oil stains on the material surface to avoid affecting the cutting quality. Then check whether the parameters of the CNC machine tool are normal, including the laser power, focus position, and gas flow of the laser head, to ensure that the equipment is in the best working condition;

[0035] ② Data import and setting: Import the CAD drawing or vector graphic file to be cut into the control system of the CNC machine tool, ensure that the file format is correct and the path is clear, and set appropriate laser power, cutting speed, and focus position parameters according to the material type and thickness;

[0036] ③ Positioning and calibration: Place the base material precisely at the predetermined position, ensure that the material edge is aligned with the cutting path, start the equipment for a trial run, check whether the cutting path is correct and whether the cutting effect meets the expectations. If there are deviations, adjust the parameters in time or reposition the material;

[0037] ④ Start cutting: After confirming that everything is ready, start the CNC machine tool for formal cutting. During the cutting process, the operator should closely monitor the operation of the equipment to ensure the smooth progress of the cutting process. After cutting is completed, use a vacuum cleaner or brush to remove the waste materials and debris on the workbench to keep the working environment clean. Then, conduct an appearance inspection on the cut base material sheet to ensure that there are no obvious defects or flaws.

[0038] Further, in the coating of the reflective layer (c), a roller coater or spraying equipment is used to evenly coat the reflective material on the surface of the base material sheet, and the reflective layer is fixed by thermal curing or UV curing;

[0039] The roller coater can precisely control the thickness and uniformity of the coating, ensure the consistent distribution of the reflective material, avoid the phenomenon of local over-thickness or under-thickness, and the roller coater is suitable for different types of base materials such as PVC, PET, and composite paper. The operator can adjust the coating parameters according to the material characteristics to achieve the best effect. The use of modern spraying technology can accurately control the spray volume, reduce material waste, and improve production efficiency at the same time.

[0040] Further, in the step of printing graphics and texts (d), screen printing, offset printing, or digital printing technology can be selected according to the design requirements to ensure clear graphic information and bright colors;

[0041] When using screen printing, the method of pressing the ink onto the base material through a template is used to ensure that the words and patterns are clearly visible. Screen printing can achieve complex color effects by overprinting different colors of ink multiple times, thereby producing a thicker ink layer, making the colors more saturated and having a stronger three-dimensional sense. Moreover, the ink used in screen printing usually has high light resistance and abrasion resistance, and can maintain bright colors even when exposed to the external environment for a long time;

[0042] When offset printing is used, the image is transferred to the substrate by means of a rubber blanket, enabling high resolution and ensuring uniform ink distribution during large-area printing, guaranteeing that the graphic and text information on the entire card surface is clear and consistent, and having a high color reproduction degree. Offset printing adopts the four-color printing (CMYK) method, which can accurately reproduce the colors in the design draft, making the color of the final product close to that of the original manuscript, and can also achieve delicate color transitions and rich layering effects;

[0043] When digital printing is used, by directly controlling the printhead or laser head through a computer, precise control of pixels can be achieved, ensuring high accuracy and consistency of graphic and text information, enabling rapid sample generation, facilitating immediate confirmation and adjustment by designers and customers, improving work efficiency, and being able to reproduce a wider color gamut to meet the color requirements of high-end designs.

[0044] Furthermore, in the step of laminating or coating the protective layer (e), the selection of the transparent plastic film or UV varnish should consider its abrasion resistance, weather resistance, and environmental friendliness;

[0045] When using a transparent plastic film, a strong physical barrier is formed, which can effectively prevent the printed layer from being scratched and worn, extending the service life of the card. When using UV varnish, the UV varnish has good antioxidant properties, which can prevent the printed layer from aging due to oxidation, ensuring that the card maintains a good appearance for a long time.

[0046] Furthermore, after the quality inspection (g), there is also a packaging step, using a dust-proof bag or vacuum packaging method to protect the finished color card from external contamination;

[0047] The detailed process of this packaging step is as follows:

[0048] ① Prepare packaging materials: Use dust-proof bags, vacuum packaging bags, labels, and sealing machines, and check whether they meet the environmental protection standards and product quality requirements;

[0049] ② Classify and sort the finished color cards: Classify and sort the finished color cards that have passed the quality inspection according to different specifications and batches to ensure that products of the same batch can all be evenly packaged;

[0050] ③ Remove surface dust: Before packaging, use a clean soft cloth or compressed air gun to gently wipe the surface of the color card again to ensure that there is no dust or other contaminants remaining. For color cards that need to be individually packaged, use dust-proof bags to package them one by one, carefully place the color cards into the dust-proof bags, and ensure that the edges are not damaged;

[0051] ④ Sealing treatment: Use a sealing machine to heat-seal or tape-seal the dust-proof bag to ensure that the bag is well-sealed and prevent external dust from entering. For the color cards that need to be batch-packed, the vacuum packaging method can be adopted. Arrange a certain number of color cards neatly in the vacuum packaging bag, pay attention to avoid overlapping or squeezing. Use a vacuum packaging machine to evacuate the air in the packaging bag, remove the air inside the bag, and ensure that the color cards are closely attached without being deformed under pressure. After completing the evacuation of air, immediately use a sealing machine to seal the vacuum packaging bag to ensure that the packaging bag is completely closed and prevent air from entering again;

[0052] ⑤ Add identification and labels: Add necessary identification and labels to each packaging bag, including product name, specifications, batch number, production date, and expiration date information, which is convenient for subsequent management and tracking. Put the packaged color cards into appropriate outer packaging boxes, and use foam boards or bubble films for cushioning protection to prevent collision or extrusion during transportation;

[0053] ⑥ Storage or shipment: Store the packaged finished color cards in a dry and well-ventilated warehouse, avoid direct sunlight and humid environment to ensure long-term preservation; or according to the order requirements, take out the finished color cards from the warehouse and prepare for shipment. Check again whether the packaging is intact before shipment to ensure safe delivery to the designated user location.

[0055] 1. This process adopts the unique effect generated by the reflective layer to enhance visual attraction. By using a holographic film or a reflective film with a microprismatic structure, it can produce different color change effects at different angles, increasing the visual impact and attraction of the card. Moreover, the holographic film or the reflective film with a microprismatic structure is beautiful and also has complex patterns and details, enhancing the anti-counterfeiting performance of traditional color cards;

[0056] 2. High-quality printing achieved through screen printing, offset printing or digital printing technology ensures the clarity and vivid color of the graphic information, improving the overall visual effect;
