Synthesis digital image generating method for e.g. package preform, involves calculating synthesis digital image from marking data, from initial digital image and based on disposition of indexing mark before deformation of mark

摘要

The method involves applying indexing mark (7) on the surface of a standard sample (6) of an object. The sample is deformed according to a deforming process. Marking data representative of measurement of disposition of the mark, is stored. A synthesis digital image is calculated from the data, from an initial digital image representative of initial graphical composition and based on the disposition before deformation of the mark.
