Color onion printing is a special printing process that combines decorativeness and practicality. With its unique sparkling texture and rich colors, it has become a popular choice in the printing and packaging industry to enhance product grade. Its core principle is to mix color onion powder with UV ink. When the ink on the printed matter is not dry, the color onion powder is attached to the surface by laying, and after drying and setting under ultraviolet irradiation, a granular shiny effect is formed, creating a visual experience different from ordinary printing.
Introduction to Color Onion Printing Process
The key to this process lies in the selection of color onion powder and process control. Color onion powder comes in a variety of colors, and particles of different densities and sizes can be selected according to needs. The common hexagonal color onion powder can present a more uniform sparkling effect. During printing, a lower mesh screen is required. In some processes, a columnar intaglio plate is made by laser engraving to accurately control the ink thickness and color onion powder distribution, ensuring clear patterns and uniform particles, and avoiding problems such as powder falling and caking.
The prominent features of color onion printing are delicate texture, soft luster, both pearl-like warmth and metal-like shine, with strong visual impact. At the same time, it can improve the wear resistance and water resistance of printed matter. Compared with the pearl printing process, it has a more obvious granular feeling and more prominent sparkling effect, with moderate cost and convenient operation, which can be flexibly applied to local decoration or full-page printing.
This process has a wide range of application scenarios and is suitable for various substrates such as white card, glass card and gold-silver card. It is often used in high-end packaging, stationery, greeting cards, cigarette packs, cosmetic gift boxes and other products, as well as thermal transfer decoration of clothing and luggage. In practical application, it is often used in conjunction with lamination, UV and other processes to further enhance the high-end texture of products, help brands create unique visual identifiers, and meet the market demand for personalized and high-quality printed products.
