Also known as hot stamping, it is a general term for printing various foil images on a substrate by means of heat and pressure. According to the different hot stamping materials, it is divided into gold foil hot stamping, silver foil hot stamping, lacquer stamping, powder stamping, electro-aluminum hot stamping, etc.; according to different hot stamping processes, it is divided into positive hot stamping, negative hot stamping, Bronze stamping, layer hot stamping, etc. Foil stamping is a type of hot stamping. Foil materials usually include various types of gold foil, silver foil, copper foil, powder foil, and the like. When performing hot stamping, the foil should be cut into strips according to the size of the image, then laid on the graphic part of the printing plate, then put on the printing plate, and finally pushed into the foil machine to heat the plate to make the plate The foil on the image is firmly adhered to the substrate. The hot stamping feature is that the printed graphic is bright, bright and dazzling, magnificent, noble and hot, and the hot stamping is not easy to fall off. Foil hot stamping is mainly used for the appearance and decoration of high-end foods, drinks, supplements, medicines, clothing, gifts and other paper cartons.
The quality of hot stamping depends to a large extent on the correct choice of hot stamping foil material. Different hot stamping methods, hot stamping processes, and even different hot stampings have strict requirements on the foil used. The foil material used must match the material of the substrate. In addition, in the hot stamping process, the temperature and pressure requirements are extremely strict. In other words, it is quite difficult to achieve perfect hot stamping quality. Recently, Bobst USA Co., Ltd., a Bobst Group of the world's largest multinational company, wrote an article on cardboard die-cutting and hot stamping in the folding carton section, talking about the key to high-quality hot stamping. This article will introduce a brief introduction to it, in order to learn from relevant readers.
Foil hot stamping is used to adjust the surface decoration of the product packaging carton, which can significantly enhance the gloss and shine of the carton decoration, making it bright, colorful and more luxurious. In the supermarket shelves, in the dazzling array of colorful packaging products, the high-grade packaging carton with foil hot stamping is more dazzling, attracting attention, forming a strong sense of goodwill and desire to purchase, thus greatly increasing the number of The competitiveness of beautifully packaged goods. If you're just working on a foil hot stamping factory, or considering getting ready to step into the technology, let's explore a few related issues that may make you less detours on the path to beginners.
In order to obtain the perfect high-quality foil hot stamping effect, we must first carefully plan and design the entire process, from the structural design of the carton, the graphic design and layout, to the hot stamping surface. The final decoration must be correct. The selection of hot stamping foil, the precision of foil bonding and the accuracy of press molding are very important. Die cutting and measurement data must be as accurate as possible. In addition, it is necessary to ensure that the bonding position of the foil is accurate. If there is an error in the bonding position of the foil, the high precision of the molding is not helpful.
Specific hot stamping operators and quality control personnel must undergo specialized technical training and require the necessary knowledge. Because this high-tech foil stamping technology requires skilled workers with sufficient expertise and practical experience to be competent. Usually, operators and quality control personnel should be encouraged to spend more time studying, researching and exploring foil hot stamping technology and technology, constantly summarizing both positive and negative experiences, continuously improving operational skills and technical level, and improving the precision of foil stamping. Quality level.
One of the trickiest and most important issues for those who are entering the foil stamping door is how to properly select the most suitable foil material. In general, people who are new to foil stamping often think that the correct choice of hot stamping color is the most important, but the opposite is true, because the right choice of the most suitable foil material is far more important than the correct choice of color. The key to the correct choice of foil material is that the selected foil material must match the material of the substrate; the second is to meet the processing requirements. These two points play a decisive role in the quality of foil stamping.
The hot stamping effect obtained by selecting different types of foil materials is also different. The foil materials purchased from different suppliers also have different degrees of difference in color and processability, so it is necessary to carefully examine the foil supplier's credit to ensure that the purchased foil is not only of superior quality but also conforms to The corresponding process requirements. In addition, before starting the hot stamping process, you must obtain the user's approval of the foil of your choice, in order to avoid problems caused by the inconsistent material selection and unnecessary economic losses due to the replacement of the foil material.
