Bending is the application of folds to a sheet using special equipment. The peculiarity of this method is the clearly defined place where two parts of the printed product are joined. Bending is used to create folds on high-density paper, which avoids cracking and deterioration of the appearance of the product.
Folding is the process of bending printed paper. There are several options for folding sheets: parallel, perpendicular, or combined. In parallel folding, all folds are parallel to each other. In the case of a perpendicular, each successive bend of the sheet is located relative to the previous one at a right angle. Combined folding combines bends of different types.
