What are the requirements for printing on paper used in paper shelves? Let's take a look at the different papers and then understand the requirements for printing on paper.
1, board paper
Paperboard is a laminated structure of paper with a wide range of 220g/m2, 240g/m2, 250g/m2, etc., which can be selected from the largest of various materials. The paper has a certain hardness and surface strength, especially the surface coated with the coated white paper, the ink is not easy to penetrate, the amount is small, and the color and dot transfer property of the printed image are good. However, the disadvantage is that the smoothness is poor, the printing speed is slow, and the hand feel is rather rough compared with the cardboard.
2, coated paper
Coated paper, also known as printed coated paper, is made by applying a layer of white syrup to the base paper and calendering it. The surface of the paper is smooth, highly elastic, and has low elasticity, and the ink is well absorbed and received.

Therefore, when selecting the color to be printed, it must be considered that the ink has high color saturation and strong tinting strength. Otherwise, the printed color and the desired color will vary greatly. Ink viscosity is one of the main factors that affect printing color and need to be controlled in corrugated board printing.
