picking

A lifting of the coating of a paper, or even the paper fibers themselves, from the surface of a sheet. It generally occurs during printing and is caused when the lifting stress resulting from tackiness of the ink exceeds the strength of the paper or its coating. The defect itself does not register from sheet to sheet, but its effect may be seen on succeeding sheets. Picking can usually be overcome by reducing the viscosity of the ink and/or running the press at a lower speed. (17 , 323 )
