Cockling is caused by an excessive amount of heat or humidity applied during pressing.
Cockling occurs on the front and / or back cover of an improperly pressed book, giving the appearance of waves throughout the cover. This defect is common to pressed books — either in an isolated area of the cover or over the entire cover — and it occurs when an excessive amount of heat or humidity is applied during pressing. Signs of cockling may not become apparent until some time has passed after pressing. Cockling can be corrected nearly 100% of the time with a proper pressing.
