Offset printing paper is a relatively advanced book printing paper, which has higher requirements for printing ratio, stretch rate and surface strength. The acidity and alkalinity should also be close to neutral or weakly alkaline.

Disadvantage: The disadvantage is that the color printing effect is general (but pearl paper is used to print black and white drawings, and the effect is acceptable when it encounters a few color parts, so it does not matter). Another disadvantage is that it is not particularly easy to bond, and it needs to be fixed with the help of tweezers for a while, but it is still very strong after bonding.
