Method for determining the surface quality of a substrate and associated machine for converting the substrate
First Claim
1. A method for determining the surface quality of a substrate passing from an initial state of an initial substrate into a converted state of a converted substrate during a conversion process in a substrate-converting machine in a packaging production line, the method comprising the steps of:
- prior to performing the conversion process of the initial substrate in the substrate-converting machine in the packaging production line, acquiring first information relating to surface defects detected on the initial substrate,after performing the conversion process of the initial substrate in the substrate-converting machine, acquiring second information relating to surface defects detected on the converted substrate,processing the first information and the second information by a processing unit, andclassifying the converted substrate by the processing unit as a function of the first acquired information relating to the surface defects detected on the initial substrate and as a function of the second acquired information relating to the surface defects detected on the converted substrate, wherein the classifying distinguishes the surface defects detected on the initial substrate from the surface defects detected on the converted substrate.

Abstract
A method for determining the surface quality of a substrate passing from an initial state into a converted state during a conversion process including the steps of acquiring first information relating to surface defects detected on the initial substrate, acquiring second information relating to surface defects detected on the converted substrate, of processing the first information and the second information, and of classifying the converted substrate as a function of the first acquired information relating to the surface defects detected on the initial substrate and as a function of the second acquired information relating to the surface defects detected on the converted substrate.
