A wonderful shopping experience, in addition to high-quality goods, the design of the packaging bag can also add infinite charm to the product! Have you ever wondered how these dazzling packaging bags are made?
Today, let us unveil the mystery of packaging bag printing technology! Whether it is those colorful food packaging bags or those delicate and elegant cosmetic packaging bags, they are inseparable from these important printing processes.
Gravure printing technology originated in Germany in the late 19th century. By engraving grooves of patterns or text on the printing plate, the patterns are transferred to the printed material using the pressure and ink of the printing press. This technology is often used to print high-quality images and textures.
Gravure printing can achieve high-precision image and texture effects because the surface of the printed material is concave, and the pattern or text can be transmitted very clearly.
Therefore, gravure printing is very suitable for various materials, including paper, plastic, metal, etc., and is widely used in packaging, decoration and artwork production.
In addition, gravure printing also has the characteristics of fast printing speed, bright colors and strong three-dimensional patterns.
In the field of plastic packaging bags, gravure printing can not only achieve fine printing effects, but also show rich textures and layers, and is not easy to wear or fade, which greatly increases the attractiveness, texture, visual effect and durability of packaging bags.
Letterpress Printing
Letterpress printing can be traced back to ancient woodblock printing. Letterpress printing originated in China.
The raised parts of the printing plate absorb the ink, which is then transferred to the printed material through pressure. This process can be automated through a printing press to ensure printing accuracy and efficiency.
Letterpress printing is suitable for a variety of different types of materials, such as paper, plastic, metal, etc., and the printed products have a strong sense of touch and three-dimensionality. Letterpress printing has a high printing speed, so it is also suitable for mass production. Of course, letterpress printing also has some shortcomings. The prints obtained by letterpress printing technology are relatively low in fineness and cannot show very delicate patterns and details.
Screen Printing
Screen printing technology is also an ancient and widely used printing technology. It originated in ancient China. Screen printing is to fix the screen, apply ink or pigment on the top of the screen, and then use a scraper to push the ink onto the screen, and then transfer it to the object to be printed through the mesh.
Screen printing can achieve a variety of effects and applications, printing complex patterns and colorful designs. In addition, screen printing has low cost and fast speed, which is suitable for large-scale production and small-batch customization. But screen printing is difficult to achieve gradient colors and high-definition images.
Digital printing technology originated in the late 20th century and rose with the rapid development of computers and digital technology. Unlike traditional printing technology, it does not require plate making and directly converts digital information into printed images.
The working principle of digital printing is to convert images or texts into digital signals through computers, and under the action of the inkjet head or electronic sensor of the printing press, the pigment or ink is sprayed onto paper or other materials to form a printed image.
Digital printing can achieve personalized customization, high flexibility, and can quickly produce small batches of printed products, avoiding the large-scale plate making process of traditional printing. However, the printing cost is high and the price is expensive.
