In this paper, a 3D finite element model was built up to simulate the ink marking process. Due to large deformation and strains arisen during the process, the Mooney-Rivlin hyperelastic constitutive model with parameters characterized through a compression test was employed to model the mechanical response of the rubber inker. A parametric study focused on the effect of the curvature of the inking surface was carried out. Results from this study would be conducive to the optimization of the ink marking process.
