Introduction

A single look at the 3-dimensional animation before shows a fact: today we are no more capable to imagine a container commercially successful without labels.   From this basic observation derives the relevance of the Label inspection, the one devoted to assure that labels are present or correctly applied.  The Label Electronic Inspectors are differentiated following the label detection principle (photoscanner or camera) and the place where the inspection is performed.  

They exist two distinct label inspection operation principles:

  • luminous re-emission of the label surface, irradiated by a LED and later detected by an analog photo-sensor based on a phototransistor (photoscanner);
  • evaluation of CCD- or CMOS-camera images.

applied, alternatively:

  • at-the-Conveyor;
  • in-the-Labeller Machine.
