Scoring is a specialized process used to define a precise fold line on lighter materials such as paper and light packaging board, like envelopes or brochures. It applies controlled pressure using a specialized blade to create a minute, precise score that only compresses the material fibers and guides the fold direction. This method is crucial for materials with sensitive print or laminate coatings, as the lighter touch prevents cracking or breaking the surface, resulting in a perfectly smooth edge and clean structural finish.

In contrast, Creasing is applied to thicker, heavier materials such as folding cartons, rigid boxes, and heavy corrugated board. Creasing uses more forceful tools to cause a deeper, permanent structural deformation, creating both a pronounced groove and a raised surface (bead) on the material. This aggressive displacement of fibers is necessary to achieve a secure, stable, and durable fold that is essential for the structural integrity and stability of heavier packaging items in the supply chain.
