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 )
