1. A method for predicting and/or determining rollover for a part generated by virtual fine blanking, in which a digital image of a cutting contour of the part is generated, provided as an image file and subjected to image analysis in an image processing device, comprising: a) coloring points located inside a surface area defined by the cutting contour and points located outside of the cutting contour using colors that can be distinguished from one another; b) carrying out at least a one-time blurring process on the cutting contour of the part using a filter that is calibrated for a material of the part and a ductility thereof so as to generate different color gradation values; c) renewing coloring of the colored points located outside of the cutting contour using the original color used for the first coloring; d) processing the color gradation values to form a measure of a residual thickness on the cutting contour of the part after fine blanking in comparison with a starting thickness of the part prior to fine blanking; and e) determining the rollover based on the individual color gradations on the cutting contour by associating the gradations with a residual thickness in the region of the cutting contour.
