The document describes a new missing label detection system called ELCAM from Erhardt+Leimer that uses a smart camera to reliably detect missing labels during narrow web label production. ELCAM replaces complex sensor arrays with an easy setup process that requires just 5 seconds of training. It increases productivity by avoiding waste from undetected missing labels and reduces costs.

Missing Label Detection
ELCAM - the ideal system to avoid custo-
mer complaints
Erhardt+Leimer, for years a world-leading
manufacturer of web guiding equipment and
inspection technology has further developed
ELCAM, a vision camera based missing label
detection system. ELCAM from
Erhardt+Leimer stands for significantly bet-
ter print and production quality thanks to in-
novative new smart camera technology.
The new ELCAM Missing Label Detection
system is a special solution for the narrow
web label industry. The system is easy to in-
stall, easy to use and robust in operation.
Thanks to this new development, label prin-
ters are able to avoid waste and to increase
the quality of the label production process.
Due to the very quick job setup times, the
productivity will increase significantly. The
system consists of the smart vision camera
ELCAM in combination with LED light sour-
ces, a small controller to handle stop signals
for the production process if needed, and a
touch screen panel with a self-explaining in-
tuitive graphical user interface.

3. ELCAM Missing Label GUI
The ELCAM graphical user interface has
been designed for easy and intuitive operati-
on in order to support operators during their
daily work. High image resolution in combi-
nation with high-precision detection algo-
rithms and a clearly structured touch screen
panel are the key features of the ELCAM
Missing Label System.
The live image supplies direct feedback to
the operator in order to keep him informed
about the current status of the system. An
automatic exposure control constantly
makes sure that the image is always well il-
luminated. Together with the teaching func-
tion it makes life easier for operators during
order change.
