Square Gold Stickers, that is, square gold foil stickers, its process introduction can be mainly carried out from the following aspects:
1. Material selection
Gold foil material: Gold foil is the main material for making gold stickers, with bright metallic luster and good ductility. High-quality gold foil can ensure that the stickers present a noble and elegant effect visually.
Substrate selection: The substrate of the sticker is usually made of paper, PE (polyethylene), PVC (polyvinyl chloride), PP (polypropylene) and BOPP (biaxially oriented polypropylene). These materials have good printing suitability and pasting performance, which can meet the use requirements in different scenarios.
2. Production process
Design and plate making: According to customer needs, the designer will first draw the pattern and text of the sticker and make the corresponding printing plate. The clarity of the pattern and the accuracy of the text need to be ensured during the plate making process.
Printing: The designed pattern and text are printed on the substrate through a printing press. During the printing process, the uniformity and drying speed of the ink need to be controlled to ensure the printing quality.
Hot stamping/hot stamping: In order to enhance the metallic texture of the sticker, hot stamping or hot stamping is usually used. This step is to apply a layer of metal foil on the printed substrate, and then firmly attach the metal foil to the substrate by high-temperature embossing.
Surface treatment: According to customer needs, the sticker can be treated with matte, glossy, laminating and other surface treatments. Matt treatment can reduce the reflectivity of the sticker, making it look softer; gloss treatment can enhance the gloss of the sticker, making it more dazzling; laminating treatment can improve the wear resistance and waterproofness of the sticker.
Die-cutting and waste discharge: Use a die-cutting machine to cut the sticker according to the designed shape and remove excess waste. This step requires ensuring that the shape and size of the sticker are accurate.
Quality inspection: Quality inspection of the produced stickers, including checking the clarity of the pattern, the accuracy of the text, the strength of the metal texture, and the adhesive performance of the sticker. Only stickers that have been strictly inspected can be shipped out of the factory.
3. Introduction to special processes
Gold/silver stamping: In addition to the traditional hot stamping/hot silver process, gold/silver stamping can also be used. This process is to directly press metal powder or metal foil onto the substrate to form patterns and text with a metallic texture. The stickers produced by this process have a stronger metallic texture and are not easy to fall off.
UV printing: UV printing is a printing method that uses ultraviolet curing ink. This printing method can produce patterns and text with a three-dimensional sense and glossiness, making the stickers look more vivid and attractive.
Anti-counterfeiting technology: In order to combat counterfeit and shoddy products, some square gold foil stickers also use anti-counterfeiting technology. These technologies include special ink printing, microtext printing, laser anti-counterfeiting, etc. These anti-counterfeiting measures can effectively protect the rights and interests of consumers and ensure the authenticity of the products.
4. Application scenarios
Square gold foil stickers are widely used in various fields due to their noble and elegant appearance and good adhesive performance. For example, they can be used for packaging and labeling of cosmetics, anti-counterfeiting logos of high-end products, decoration of festivals and celebrations, etc. In these scenarios, square gold foil stickers can enhance the added value and brand image of products and bring consumers a better use experience.
