A paper deformity characterized by a tendency to curl. Paper that is wrapped very near the core of a paper roll and then sheeted will have a curl if it has not been decurled properly. Roll-set curl always occurs across the grain. Roll-set curl will not usually occur in every sheet, but rather at various intervals throughout the pile. Roll-set curl is incurable, the only solution being to pull the curled sheets from the paper pile and discard them. (See Curl.) Roll-set curl is also called wrap curl or reel curl.
