White line

Mis-registration is an error in the printed image which can occur in multicolour printing. If the different colour separations are not exactly superimposed, the printing substrate emerges between two image elements with a different tonality. It is often just hundredths of a millimetre which cause a white line. Trappings offer a remedy in colour separation.
