Effect of plate bending deformation on frame radial dimensions was studied through simulation of orthogonal experiment. Mathematical model of plate bending deformation was derived. The influencing parameters causing radial dimensions change of graphic were analyzed using orthogonal experiment. The result showed that plate material thickness is key factor influencing radial dimension change. The purpose was to provide guidance for offset production practice.
