Printing and scanning change what you intended to print. This matters in variable data security printing, since there is information encoded there. My friend and colleague Marie Vans explores this issue in another NIP25 paper posted here:

The approach, structural pre-compensation, is also known as "trimming" or "shaving". Interestingly, without it, not only are the barcodes harder to read, but the would-be counterfeiter gets a "free pass".
