Horse-riding binding, also known as "horse-riding binding", is a binding method for some thin magazines and copperplate color pages. Fold the paper in half at the waist and bind it at the crease.

The gram weight of coated paper refers to the weight of paper per square meter.

Coated paper is made by coating a layer of coating liquid on the base paper and then super-calendering. The basis weight is 90-250g, which can be divided into double coated paper and single coated paper.

There are three product numbers: special number, No.1 and No.2. Special coated paper is used to print fine products with net wire150g or more; 1 coated paper is used for printing 120- 150 screen number; No.2 coated paper can be used for printing products with net wires below 120g. Coated paper is not resistant to folding, and once creases appear, it is extremely difficult to recover.
