Paper Shopping Bags have a variety of printing processes to meet different design needs and brand styles. The following are several printing processes commonly used for Paper Shopping Bags and their characteristics:
Color printing: Color printing is one of the most commonly used printing methods for Paper Shopping Bags. Through overlay printing of four colors (or more colors), colorful patterns and text can be reproduced, making paper bags more recognizable and attractive. The color printing effect is flat and the colors are bright, which is suitable for conveying various brand images.
Gravure printing: Gravure printing has the characteristics of thick ink layer, strong three-dimensional effect and clear layers. In the printing of Paper Shopping Bags, gravure printing can present rich layering and delicate pattern effects. In addition, the pattern accuracy of gravure printing is high and the error is small, which can ensure the printing quality.
Letterpress printing: The graphic part of the letterpress printing plate is higher than the non-graphic part. During printing, the ink can only effectively cover the higher graphic position without affecting the non-graphic part. This printing method is often used to print simple patterns such as text and lines on Paper Shopping Bags. It has the characteristics of thicker ink and good color rendering.
Screen printing: Screen printing uses a screen perforated plate and printing material to obtain graphics by scraping. Screen printing has the characteristics of strong three-dimensional effect and wide adaptability, and can print various complex patterns and text. In addition, screen printing does not have high requirements on the material and shape of the substrate, so it is widely used in the printing of Paper Shopping Bags.
Hot stamping and silver hot stamping: Hot stamping and silver hot stamping are printing processes that heat a metal printing plate and apply foil to the paper bag to emboss gold or silver text or patterns. This process can increase the texture and class of paper bags and is often used in the production of Paper Shopping Bags of high-end brands.
UV printing: UV printing is a printing method that uses ultraviolet drying and curing. In the printing of Paper Shopping Bags, UV printing can print various texts and patterns, and increase its brightness, artistic effect and wear resistance through a layer of UV varnish. UV printing has the characteristics of fast drying, bright colors, wear resistance and durability.
Each of the above printing processes has its own characteristics, and the appropriate printing method can be selected according to the design needs and brand style of the Paper Shopping Bag.
