After Printing - Hot Foil Stamping Process
1. What is Hot Foil stamping? The hot foil stamping process uses the principle of hot-pressing transfer to transfer the aluminum layer in the anodized aluminum to the surface of the substrate to form a special metal effect. Due to the main material used for hot stamping being anodized aluminum foil, hot stamping is also called anodized aluminum hot stamping.
Hot foil stamping does not mean that the hot stamping is gold. There are many kinds of hot foil stamping paper materials, such as gold, silver, laser gold, laser silver, black, red, green, and so on.
02. What is the classification of the Hot Foil stamping process? The hot foil stamping process is divided into the hot foil stamping process and the cold foil stamping process. Hot foil stamping is a process in which metal foil is transferred to the surface of printed matter or other items by hot pressing to increase the decorative effect. Hot foil stamping is further divided into ordinary flat hot foil stamping, three-dimensional hot foil stamping (commonly known as embossing and embossing hot stamping), and holographic positioning hot stamping.
Cold foil stamping is the process of transferring metal foil to the surface of prints or other items without heating, only through the force of pressure and adhesion, and peeling.
03. What are the commonly used Hot Foil stamping materials? The production of hot foil stamping plates mainly adopts
photographic corrosion technology and electronic engraving technology, and the material is mostly copper plate or zinc plate. The copper plate has a delicate material, and the surface finish and heat transfer effect are better than those of the zinc plate. The use of a high-quality copper plate can improve the gloss and outline clarity of the hot stamping graphics. The traditional photographic corrosion technology has a simple process, low cost, and short service life. It is mainly used for hot stamping text, thick lines, and general images. The hot foil stamping plate produced by electro-engraving can express rich and delicate layer changes, and its printing resistance is high, which is suitable for card, and packaging products with fine product quality requirements and large batches.
