What is Creasing?

In the paper industry, creasing refers to a way of changing the shape of the paper. In order to be able to fold a sheet more easily, the paper gets weakened along the so called “creasing line”, i.e. a channel is formed along the paper, which weakens its structure as the material is stretched all the way along the fold line. When the sheet of paper is turned over, the bottom of the channel score is visible as a thin linear elevation.
