Introduction of Gravure Printing

Gravure printing is a direct printing method. The printing materials can be very wide, but it is commonly used to print high-grade paper and plastic film. It imprints the ink contained in the gravure pits directly onto the substrate. General soft materials can be used as gravure printing substrate, such as plastic, paper, aluminum foil, especially for some easy to extend deformation materials, such as textile materials, has better adaptability. Because of the fine lines and the difficulty of counterfeiting, gravure printing is also used in the printing of securities, such as banknotes, stocks, gift certificates, stamps, certificates of commercial prestige or stationery, etc. Due to its high cost, it is not suitable for printing a small number of prints, and is generally used in large quantities of prints.

Introduction of Flexographic Printing

Flexographic printing is a printing method that uses a flexographic plate and transfers ink through an anilox roller. For flexographic printing, the printing plate generally adopts a photosensitive resin plate with a thickness of 1-5mm. Inks are divided into three categories, namely water-based inks, alcohol-soluble inks, and UV inks. Because the ink used in flexographic printing is environmentally friendly, it has been widely used in food packaging printing and has a bright future.

Advantages of Flexographic Printing

1. Low cost
2. Simple equipment
3. High efficiency
4. Widely used
5. Good quality
6. Environmental protection
7. Wide range of suitable printing media

The difference between Gravure Printing & Flexographic Printing

In terms of production process, the printing of roll materials, no matter whether the gravure process or the flexo process is used, has almost the same requirements, and there is no difference in unwinding and winding, tension control, drying and monitoring systems. For the same job, gravure printing and flexographic printing require about the same amount of work. The difference between the two mainly lies in the different processes used. The gravure printing uses an engraving cylinder, while the flexographic printing uses a soft and elastic printing plate. In addition, the investment of gravure printing process is generally 20%~30% higher than that of flexographic printing. Compared with flexo printing products, the visual effect of gravure printing products is stronger, and the quality is generally higher.
