The crease lines on the notebook: A practical art of writing and organizing

Most people have had this experience: when writing in a notebook, if you tear off the paper along the crease line on the edge of the page, the edges will be neat and tidy, without any rough edges or tear marks. This crease line printed on the edge of the paper is a detailed presentation of "user experience" in stationery design, integrating industrial design thinking into daily writing scenarios.

The design of the creasing line for notebooks has clear technical standards. The crease line of a horizontal line notebook is usually 1.5 to 2 centimeters away from the edge of the page and parallel to the horizontal line of the inner page. This not only does not affect the writing space but also ensures the integrity of the paper after tearing. The crease line of the loose-leaf notebook is closer to the binding side. Combined with the perforated design, it enables the single-page paper to be both fixed in the clip and easily removed. For professional stationery such as sketchbooks, the crease line will also be adjusted according to the weight of the paper - the higher the weight of the drawing paper, the deeper the crease, ensuring that it can still be smoothly torn off after carrying the paint and avoiding damage to the picture.

In addition to its practical functions, creasing lines also carry certain usage habits. Students often use creasing lines to mark key page numbers, while office workers quickly organize meeting minutes through creasing lines and mark pages that need to be archived separately. Today, with the increasing popularity of digital office work, the crease lines on notebooks have not been replaced. The "physical marking" and "convenient tearing" experience they bring are something that electronic documents cannot replicate. This subtle trace establishes a tacit understanding between the paper and the user, making writing and organizing more efficient.
