Printing method of UV label paper

A diverse array of printing techniques exists for UV self-adhesive label paper, each tailored to specific characteristics and usage scenarios. Here's a look at some of the most common ones:

• Letterpress Printing: Ideal for labels with basic patterns or designs, it offers simple color printing with mesh. Letterpress machines often require specialized adjustments like enhanced tension control and film surface treatment.

• Offset Printing: Renowned for its intricate graphics and vibrant color layers, it's a perfect choice for large-scale printing. Offset presses can handle UV self-adhesive label paper in a single machine, but UV curing units may be necessary for non-absorbent films.

• Flexographic Printing: This cost-effective method boasts a simple machine structure and print quality comparable to offset and gravure printing. Using water-based and UV inks, it's environmentally friendly. It's particularly suitable for high-quality label printing.

• Gravure Printing: With a short ink path and reel printing, this highly automated technique uses solvent-based ink that dries quickly. It's the preferred choice for film printing and mass label production.

• Screen Printing: Characterized by intense ink colors and a strong three-dimensional effect, screen printing can utilize UV ink for film products. However, its overprinting accuracy is not as high, making it less suitable for inline film label production equipment.

When choosing a printing method for UV self-adhesive label paper, it's essential to consider factors like label design requirements, material characteristics, and production efficiency to ensure the selection of the most suitable printing technology.
