ABSTRACT:
To mount a lithoplate onto a plate cylinder of a conventional web press, the lithoplate is double crimped, a stiffener is fitted snugly between the two crimps, and the stiffener and crimped portion of the lithoplate are inserted into a longitudinal channel in a plate cylinder. The invention permits for the first time precision mounting of a lithoplate which has a stretchable base such as a polyester base. A stretchable lithoplate preferably is mounted over underpacking with which it has a high effective coefficient of friction.
