Foil Stamping

Foil Stamping is a special kind of printing that doesn't utilize ink. It is a process of applying metal foil or pigment foil to the surface of hot printed matter according to the graphic and text of the hot printing template with the help of specific pressure and temperature, putting printed matter and hot printing foil under mutual pressure in a short amount of time by using the stencil mounted on the hot printing machine.


The following are some function for Foil Stamping:


1. Surface embellishment can increase a good's added value. Products with designs that are distinctive, gorgeous, colorful, and loaded with wonderful visual effects are created via the employment of the Foil Stamping method. Combining the Gold Stamping, pressing, and embossing procedures results in a product with a strong ornamental impact.


2. Products with strong security capabilities. Anti-counterfeiting labels must be heated before being stamped in order to impart the anti-counterfeiting information layer to the attached object and stop it from peeling off and replicating. For instance, holographic positioning material could be printed with trademark identification.

Differences Between
Foil Stamping and Pad Printing

Differences Between Foil Stamping and Pad Printing

Foil Stamping is a special printing process without ink. With the help of a certain pressure and temperature, the use of the plate installed on the hot stamping machine, the graphic of hot stamping plate is transferred to the surface of product after the product and hot stamping foil are pressed each other in a short period of time. Generally speaking, foil stamping refers to the thermal pad printing process of hot stamping foil(hot stamping paper) to the surface of the substrate at a certain temperature and pressure. It's suitable for products with smooth surface. Pad Printing is an indirect offset printing process that a silicon pad head takes a two-dimensional image from a laser-engraved plate (gravure) and transfers it to a three-dimensional object. Due to the development of pad printing technology, it is now possible to print a variety of products with complex shapes, such as convex, concave, spherical, cylindrical, textures, composite corners, etc., which are impossible to achieve for traditional printing processes.


By conparison, the color of Pad Printing is limited and it can be difficult to get a colorful effect by mixing colors. The materials suitable for Pad Printing are also more limited. Generally Pad Printing can only be used for hard materials, for some soft materials, the effect is quite bad. Foil stamping has better transparency, color and texture result, and can be printed on a variety of materials including hard materials and soft materials.

Foil Stamping Quality Affecting Factors

As can be seen from the basic process, the three elements of quality for Foil Stamping are temperature, pressure, and rate. To get a perfect stamping result, it is necessary to appropriately master temperature, pressure, rate, and other process variables.

1. Temperature

All electrolyzed aluminum should be stamped at a temperature of between 10°C and 15°C. Raising the temperature is typically the first thing workers do when they encounter problems during the production process such as scorching or adhesion. A significant temperature increase during the Gold Stamping process is not advised, nevertheless, since it could damage the paste plate by causing the adhesive molecules in the adhesive layer to stick together. Warming of the dyeing layer causes both rainbow patterns and spots to appear at the same time. The aluminum in the aluminum plating layer will likewise experience an oxidation process at high temperatures, making the pigment a dark color.



2. Pressure

The pressure employed in Foil Stamping has a significant impact on the aluminum oxide's adhesion strength. If the pressure is too high, the substrate's and liner's compression deformation will be too great, which will cause paste version or thickening of the imprint. On the other side, if the pressure is too low, it is no fading, impression spotting, or other phenomena can occur since the electrolytic aluminum and substrate won't attach to one another. As a result, it's critical to maintain good control over the Foil Stamping pressure.



3. Rate

Electrolytic aluminum and substrate contact time are dependent on the rate of Foil Stamping, and speed of Foil Stamping is proportional to contact time. Fast Foil Stamping, brief contact times, a layer of hot-melted silicone resin, and an electrochemical aluminum adhesive that hasn't fully melted will prevent stamping or spots. On the other hand, slower rates, prolonged electrochemical aluminum and substrate contact, and stronger bonding are favorable for hot stamping. It goes without saying that the pressure and temperature must also be appropriate for the rate when Foil Stamping; if the rate increases, the temperature and pressure must likewise rise in step with the rate.


Advantages of Foil Stamping

  • No ink traces.


  • No ink or other obnoxious smells, such as air pollution.


  • The color pattern is only printed once.


  • Simple processes, efficient production management, and a high coefficient of product quality assurance.


  • Wide application includes leather, paper, plastic, and other materials.

Functions of
Foil Stamping

1. Surface decoration

Foil Stamping shows strong decorative effect of the product. It can improve the added value, quality and grade of the product, and make the product more competitive. 


2. Higher anti-counterfeiting performance

Foil Stamping gives the product a higher anti-counterfeiting performance, for example, use holographic positioning foil stamping for trademark identification. Products after foil stamping are more clear, beautiful, bright, eye-catching, wear-resistant, weather resistant. In graphic design, foil stamping highlights the design theme.
