What is X-Cut Test?

An X-cut test is a coating or adhesion evaluation method in which cuts are made through a printed or coated surface. It helps assess how well ink, paint, or coating adheres to the packaging substrate. The test can be useful for printed cartons, metal packaging, films, and other coated materials. Poor adhesion may result in peeling, flaking, or printing defects. Testing helps packaging manufacturers maintain consistent print quality.
