Fold Test

The Fold Test is a method for evaluating the quality of paper, particularly in books and documents. It involves folding a sheet of paper at a specific point and assessing how well it holds up after multiple folds. A good quality paper will resist tearing and maintain its integrity, while lower quality paper may tear or weaken. This test is often used in publishing and printing industries to ensure the durability of printed materials, helping to choose the right paper for longevity and wear during handling.
