A method for configuring a package labeler, and or labeling process including: providing a package defined as a computed mesh; providing a computed mesh description of a package labeler; providing operational parameters of a labeling operation for the package; simulating the interaction of the package and the package labeler according to the operational parameters of the labeling operation, the computed mesh of the package labeler and the computed mesh of the package; determining the location and/or deformation of the package mesh during at least a portion of the simulated interaction; and confirming, rejecting, or configuring the package labeler according to the determined location(s).
