What is the purpose of creasing in paper processing?

The purpose of creasing in paper processing primarily serves to create a crease for easier folding. When paper is creased, it is physically altered at specific points to form a straight indentation or line, which allows for a cleaner, more precise fold. This is especially important in applications such as brochures, greeting cards, or packaging, where accurate folds are essential for the final product's aesthetics and functionality. The creased line diminishes the risk of tearing or distorting the paper during the folding process, resulting in a professional look and ensuring that the ends meet correctly.

While enhancing visual appeal, separating colors, and adding texture can play roles in design work, they are not the core purpose of creasing. The specific intent of creasing is to facilitate easier and more effective folding, making it a crucial step in the finishing process for many printed materials.
