Crease

Crease

Definition

Crease is a line, ridge, or mark on a paper, canvas, or other surface caused by folding, bending, or wrinkling. Creases can affect the aesthetic and structural integrity of artwork or documents.

Causes

• Folding paper or artwork improperly during handling or storage.
• Compression under heavy objects, boxes, or other materials.
• Improper rolling or unrolling of flexible substrates.
• Environmental factors, such as fluctuating humidity, that weaken fibers and make surfaces more prone to wrinkling.

Visual Characteristics

• Linear marks, either raised or indented along the fold.
• May create subtle color changes along the crease line due to compression of fibers.
• Visible on both paper and flexible canvas or textile surfaces.

Impact on Artwork or Documents

• Can reduce visual appeal and perceived value.
• May lead to tearing or permanent damage if not handled carefully.
• Can complicate framing or preservation if the crease is extensive or deep.

Prevention and Care

• Store flat or properly rolled materials in acid-free, supportive enclosures.
• Handle artwork and documents with clean hands or gloves to avoid adding stress to weakened areas.
• Consult a paper conservator for valuable or delicate items that have developed creases.
• Use gentle humidification techniques under professional guidance to reduce minor creases.
