The difference between color-printed cartons and watermarked cartons is as follows:
1. Different physical properties
Color printed cartons usually refer to offset printed cartons. Suitable for fine color printing. It is printed on PS board. The paper used for printing is coated paper or white paper. The surface is smooth. It also needs to be treated with glue or UV oil to protect the ink. A special high-end effect for hanging flowers that can make surfaces brighter or darker.
The watermark carton uses a resin board or a rubber board, and the printing accuracy is much poorer. It is suitable for ordinary outer packaging boxes, usually single-color or two-color printing, and the surface is untreated. The paper used for printing is generally kraft paper, and the surface is rough.
2. Different production processes
Cardboard boxes are mostly watermarked, and water-based inks are used to print directly on cardboard through rubber/resin sheets. Usually there are single-color and two-color printing. If you need 3-4 colors, you need 2 sets of printing presses. This type of printing is inexpensive and has low color reproducibility, and is suitable for ordinary shipping packaging boxes that do not require high printing accuracy.
Color printing is different. Color printed cartons usually refer to offset printed cartons. It is printed on coated paper or white cardboard by color printing PS board. The surface is smooth and can be covered with a matte/light film to prevent discoloration. After color printing, the paper is covered with separate beer to make color printed cartons. Color printed corrugated boxes cost much more than watermarked boxes and can accept 5-8 color prints. The finished product is exquisite, suitable for high-end finished product promotional packaging.
Color printed cartons are light in weight and have good structural properties. The inner corrugated structure is similar to the arch structure, which can play the role of shock absorption and shock absorption, and has good mechanical properties. It has many good protective functions for packaged items. For example, moisture resistance, heat dissipation and easy handling. The transportation cost is low, and it is easy to realize the mechanization and automation of packaging transportation.
Changes in size and size are easy to implement and can be quickly adapted to the packaging of various items. Easy to seal and bundle, and easy to automate. It can adapt to the decorative printing of various cartons, and can well solve the problems of product protection and promotion.
