Back-Edge Curl

A printing and paper defect characterized by the waffling, or embossing, of the rear edge of a sheet of paper. Back-edge curl has the same cause as waffling, namely, the pulling and consequent distortion of the paper when pulled by thick, tacky ink films. Back-edge curl results when heavily printed areas appear too near the rear edge of the sheet. Back-edge curl can be avoided by designing the layout of the printed material so that no solid printed areas appear at the bottom of the page. (See also Waffling.) Back-edge curl is also called tail-end hook.
