Disposable paper bowl printing types and prepress issues

At present, advertisers or manufacturers also use paper bowls as an advertising medium.

Designing the pattern on the cup body can give people different drinking moods, and it is also a "symbol" for promoting a certain product. Because the product's trademark, name, manufacturer, distributor, etc., can be designed on the surface of the paper cup. When people drink beverages, they can get acquainted with the information and understand the products. paper bowls provide a platform for people to understand these new products.

Second, compare the printing methods of paper bowls

paper bowls have a variety of printing methods, and different printing methods have different printing characteristics.

Offset printing

Offset printing is the principle of using oil and water repulsion.

Film propaganda paper bowls are oil-resistant and water-resistant. The blank part is hydrophilic and oil-resistant. The images are transferred to the printing materials through a blanket cylinder. The advantages of offset paper bowls are full, vivid, and high definition. No matter whether it is a gradual change or a fine and fine line, it can be clearly displayed, making the appearance of the paper cup more beautiful and attracting the eye of the customer. But offset printing is not suitable for printing edible paper bowls, because offset printing inks are not very environmentally friendly.

2. Silk screen

Screen printing is flexible and flexible due to its flexibility and applicability. It is not only suitable for printing on soft articles such as paper and cloth, but also suitable for printing on hard articles such as glass, ceramics, etc., and is not limited by the surface shape and area of ??the substrate. However, the advantages of screen printing paper bowls cannot be well represented, and screen printing has great restrictions on the reproduction of graphics and texts, and it is difficult to deal with gradual changes and the accuracy of reproduced images.

3. Flexo

Flexo printing is called "green printing" due to the use of water-based inks. Many of the company's product packaging are now developing toward flexo printing.

Because the structure of the flexo printing machine is relatively simple, compared to the large body of the offset printing press and the high cost of materials, the flexo printing machine becomes "thin". In terms of cost, the equipment investment of the flexo printing machine is lower than that of offset printing machines of the same scale, and generally can save as much as 30% to 40%. The small investment in production has attracted the participation of small-scale printing companies. Flexographic printing is not as narrow as the screen printing in the selection of originals, and the rules on color are broader, but they are inferior to offset printing. Flexo printing is the main process currently used for paper cup printing. The print quality of paper bowls depends largely on prepress production. We will now elaborate on the issues that should be noted in prepress production.
