Delamination

Term that can mean either a general separation of the plys of any paper due to inadequate surface strength, or, in web offset lithography, a specific paper defect occurring in blanket-to-blanket perfecting presses characterized by elongated blister-like formations along the web, also caused by inadequate surface strength that causes the internal structure of the paper to rupture when the web wraps around both blankets, causing an alternating flexing force that pulls the paper apart.
