What is thermal transfer?
Thermal transfer is a special process that uses thermal transfer ink to print any image such as portraits, landscapes, LOGO, etc. on transfer paper, and then heats it to a certain temperature within a few minutes through the corresponding thermal transfer equipment, and transfers the image color on the paper to porcelain cups, porcelain plates, porcelain plates, clothes, metals and other materials. It is mainly suitable for printing on the surface of coated metals, glass, ceramics and other products, suitable for small batch production, and can be produced in single pieces.
What are the characteristics of thermal transfer:
1. Green and environmentally friendly printing, non-toxic, pollution-free, in line with international non-toxic standards.
2. Multi-color printing patterns are formed at one time, without color registration, avoiding the shortcomings of inaccurate color registration in other processes.
3. The color of the transferred image is clear and natural, bright in color, and delicate.
4. The production loss is small and the cost is low. Mass production can better show its low-end and high-quality characteristics.
5. Product Features: Milky transparent appearance, high elasticity, soft touch, washable
What is pad printing?
Pad printing is the principle of gravure printing. The tools include silicone rubber head, printed steel plate with patterns and ink. It can print various fine lines, fonts and patterns, and even four-color screen images. Whether the printed surface is concave, convex or irregular, it can still produce ideal effects. For example, printing a four-color trademark on a golf ball is one of the specialties of pad printing machines.
The process is divided into the following four points:
1. The ink is evenly covered on the steel plate by the inking oil roller.
2. The excess ink is scraped off by the scraping steel knife.
3. The ink in the pattern is picked up by the printing head descending to the steel plate.
4. The printing head is shifted and descended to the product to cover the pattern.
What is silk screen printing?
Silk screen printing is to print ink on the substrate through the mesh of the silk screen. Compared with the three major printings of convex, flat and concave, it has a wider range of printing and more advantages. There are more and more types of inks and printing materials used.
1. Screen printing is not limited by the size and shape of the substrate. It can be printed on molded objects of different shapes and concave and convex surfaces. The layout is soft and elastic, and it is a type of printing with the lowest printing pressure.
2. Screen printing has thick ink and strong adhesion. The covering power of the ink is particularly strong, and the printed images have a strong three-dimensional sense, which is incomparable to other printing methods (the thickness of the ink layer can also be controlled). Suitable for various types of inks: It has strong adaptability and can adapt to any kind of coating for printing, such as oily, water-based, synthetic resin, powder and other inks. As long as the ink and coating can pass through the mesh fineness of the screen, it can be used. It can print monochrome, or it can be overprinted and screened for color printing.
3. It has strong light resistance: It can put light-resistant pigments and fluorescent pigments into the ink through a simple method, so that the printed images and texts can maintain their gloss permanently without being affected by temperature and sunlight, and can even glow at night.
4. Convenient plate making, low price, flexible and diverse printing methods, and easy-to-master technology.
5. Screen printing process: Original → Base → Screen → Plate Exposure → Development → Drying → Printing → Drying → Finished Product Inspection → Printed Product
