[Chinese Packaging Network News] The development trend of carton printing is witnessing a diverse range of techniques coexisting, with flexographic printing showing the fastest growth. Among the most commonly used methods in carton processing are offset printing, gravure printing, flexo printing, and screen printing. Each has its own unique advantages and applications.
Offset printing is widely used in the printing of single sheets of paper, with nearly 100% of the process being done through this method. It is particularly well-suited for continuous adjustments of original prints, offering rich layers and excellent color reproduction. This technique is ideal for advertising materials, samples, wrapping paper, various types of trademarks, calendars, and even metal printing.
Gravure printing, on the other hand, dominates in high-end, high-volume printing processes. It provides distinct image layers and is especially suitable for packaging materials. It is commonly used for printing plastic bags, composite bags, wallpaper, and building materials.
Flexographic printing has experienced rapid growth, especially in medium to small batch, mid-to-low-end printing. Unlike offset printing, it is not limited by materials or processes, making it more versatile. Flexo printing is often used for printing labels, boxes, wrapping paper, and stickers.
Screen printing is ideal for applications that require a thick ink layer and high-quality results. It can be used on a wide variety of materials and surfaces, including paper, cardboard, fabric, containers, and even porcelain cans.
In terms of equipment, there are mainly two types of flexo presses used for carton printing: unit-type flexo presses and satellite-type flexo presses. Unit-type flexo presses have gained attention in recent years due to their cost-effectiveness and flexible functionality, making them a popular choice for many manufacturers.
The evolution of carton printing technology continues to shape the industry, with each printing method adapting to specific market needs. As demand for customization and efficiency grows, the role of flexographic printing is expected to expand further, offering new opportunities for printers and packaging designers alike.
