Hot stamping is an efficient and exquisite decorative technique that significantly enhances the added value and market competitiveness of products. Based on its application methods, materials, and technical characteristics, hot stamping can be subdivided into various types and forms. Below is a detailed summary of the types and forms of hot stamping:
I. Categorized by processing methods
Hot Foil Stamping: Also known as traditional hot stamping, it is one of the common methods of foil stamping. It involves heating the foil to contact the surface of an item and using pressure to bond the foil to the item's surface, creating a metallic sheen effect. Common applications of hot foil stamping include hot foil printing and hot foil stamping illustrations.
2. Cold Foil Stamping: Unlike hot foil stamping, cold foil stamping does not require heating or pressure. It involves adhering gold foil to the surface of an item using special glue or adhesive. Common cold foil stamping techniques include cold foil printing and cold foil stickers.
3. Resin Hot Stamping: A process of applying gold foil to a resin layer, which enhances and protects the hot stamping effect through the coating and curing of the resin layer. Commonly used in the production of business cards, gift boxes, and other products to elevate their quality and aesthetic appeal.
4. Computer Hot Stamping: Utilizing a computer-controlled system, high-precision hot stamping machines are employed for the hot stamping process. It can achieve intricate patterns and detailed hot stamping effects, commonly used in printing packaging, leather products, and other fields.
Section II: Categorized by Special Effects
Sand-gilded: A special gold-embossing technique that involves coating special colored powder on the gold foil and then fixing the powder to the foil using sand or other abrasives. It produces rich textures and colors, widely used in packaging and art pieces.
2. Embossed Foil Stamping: A combination of foil stamping and embossing techniques, creating a raised effect on the foil-stamped areas, resulting in a three-dimensional bas-relief appearance. During design, it's important to note that the backside will have an indentation, so the reverse side should be left blank to prevent the graphics or text from being affected.
III. Categorized according to specific process forms
Flat Foil Stamping: A common foil stamping method where only the areas to be foil-stamped have a metallic sheen, with the rest left blank or printed. The purpose is to highlight the foil-stamped areas, applying gold to important content. Compared to other processes, flat foil stamping is less challenging, has fewer chances of errors, and causes less paper wastage.
2. Heat Transfer: Contrary to flat transfer, this technique uses metal镂空 to highlight the blank spaces, while the gold-foil areas serve as a backdrop. Typically, a large graphic encircles the imagery to be highlighted, with the encircling graphic being gold-foil and the imagery being镂空, creating a reverse heat transfer effect.
3. Embossed Overprint: A crafty technique that ingeniously combines foil stamping with printing colors. The process involves printing first and then foil stamping, which requires high precision in placement, but yields excellent final results.
4. Multi-color Foil Stamping: Stamping two or more different colored gold foils on the same graphic. Requires high-precision stamping technique, with attention to the foil positioning and compatibility.
