Hot Stamping Foil Description

1. Operation Principle and Application

The hot transfer printing imaging method was invented by Mille in 1953. With the development of micro-electronic technology, lithography, semiconductor electric heating elements technology, laser technology, especially high-sensitivitive hot transfer printing imaging function material technology, the thermal transfer printer as a non-contact printing computer peripherals output hardware device has become a special kind printer. It has taken a very high market share. The thermodynamic principle of hot transfer printing imaging is making imaging material heat melt. So that it will tranfer to the imaging media and form characters and images. This can be achieved through the semi-conductor electric head or passed heat driven by computer signal onto the imaging material. Thermal transfer imaging materials coated on the belt base, known as the thermal transfer carbon ribbon or thermal transfer ribbon.

The hot stamping foil is a kind of printing consumptive material. It tranfers its ink layer to plastic, paper, composite films and other materials through the combination of heat and pressure. It is suitable for printing production date, batch number, weight and tag information in soft packing surface of food, medicine and dairy products, etc. It can print clear fonts of several languages, which sizes are more than seven, such as Chinese, Arabic numerals and English, etc. The printed fonts are characterized by legible characters, strong scratch-resistance and boiling-resistance, etc. Nowadays, they are used frequently in online identification of low, medium, high-speed continuous production line.

2. Basic components of hot stamping foil including:

a. Thin and strong dacron or other high density materials brought groups;

b. With positive end-based coatings to ensure uniform color and full color transfer;

c. Wax or resin- based ink chromatograph;

d. Outside coating layer in ink chromatograph to protect the ink color and enhance adhesion when printing;

3. Categories of hot stamping foil

To adapt to requirements of different materials and durability and according to the coating materials, hot stamping foils can be divided into wax-based and resin-based.

a.Wax base: Generally characterized by high-density, high sensitivity, leather applying, good printing and economical cost.

b.Resin base: The most durability, wipe-resistance, heat-resistance

and some recipes to prevent vapor pressure, etc.

According to different models of ribbon coders, hot stamping foil respectively has different specifications such as different width and length.

4. Technical Target:

a. Transitivity means the percentage of the printing ink layer of the hot stamping foil transfered to the media. That is to say, whether the printing ink can be transferd 100% to the media, such as plastic, paper, films, etc.

b. Adhesion refers to the abrasion resistance and the degree ofadhesive force of the printing ink layer transferd to the media, such as plastic, paper, films, etc.

c. Legibility refers to after the printing ink layer is transferred, whether the printing effect is legible and aesthetic.

d. Adaptability refers to whether the hot stamping foil can be used on various media (plastic, paper, films, etc.), in various production enviroment ( cooking, freezing, etc.) and whether the printing effect can meet the cuatomers’ requirments.

e. Temperature refers to the temperature when the hot stamping foil is used. Different charactristics of hot stamping foils have different practical using temperature and different printing effect under different temperature. Only the printing effect is best, the temperature is best.

5. Specifications:

The specification of hot stamping foil refers to:
