What are the requirements for printing on paper?
1, coated paper
Coated paper, also known as printed coated paper, is made by coating a white paste on a base paper and calendering it. The paper has a smooth surface, a high whiteness, a small stretchability, and a very good ink absorption and reception state. It is mainly used for printing high-end books and magazine covers and illustrations, color pictures, all kinds of exquisite product advertisements, samples, merchandise packaging boxes, and trademarks.
Matte coated paper, compared with coated paper, not too reflective. With its printed pattern, although the coated paper is not colorful, the pattern is more delicate and more upscale than the coated paper. The printed images and images have a three-dimensional effect, and thus the coated paper can be widely used for printing graphic arts, advertisements, landscapes, exquisite wall calendars, and character photographs.
2, paper jam
Cardboard is an ideal material for high-end packaging. Its good feel, ideal color and dot transfer conditions, as well as stiffness and surface strength are the reasons designers choose. According to the requirements of different packaging boxes, designers can make design choices for various types of cardboard.
(1) white cardboard

Designers often use glass cardboard for the packaging of pharmaceuticals and high-end cosmetics.
3, board paper
The paperboard is a laminated paper with a basis weight of 220g/m2, 240g/m2, 250g/m2, 400g/m2, 450g/m2. The range is very wide, and the largest variety of materials can be selected. This kind of paper has a certain degree of stiffness and surface strength, especially for coated white paper because it has a surface coating, printing ink is not easy to penetrate, the amount is less, and the color and dot transfer of the printed image are good. However, the disadvantage is that the flatness is poor and the printing speed is slow. Another disadvantage is that the feel is rough compared with the paper jam.
4, corrugated cardboard
The most commonly used is corrugated paperboard. The color of corrugated paperboard itself is quite dark. Therefore, when choosing the printing color, we must consider using ink with strong color saturation and strong coloring ink (such as big red). Otherwise, the printed color There is a big gap in the color of hope. The ink viscosity is the main indicator that needs to be controlled in the printing of corrugated cardboard. It is one of the main factors that affect the printing color condition.
