In combination with the E32 fiber sensors recommended for the detection of challenging marks (e.g. E32-L15), the E3X-DAC can reliably detect print marks with complex design (e.g. with included design elements) or where the contrast between print mark and background is low.

Using the colour detection capabilities in C-mode or I-mode (see Technical Information for details), the E3X-DAC can be used to detect specific coloured print marks even when black or other coloured print marks are present.

The packaging material used in many packaging machines is very often delivered in rolls and has to be cut and positioned accurately. In order to avoid waste and errors and to compensate for environmental influences, a registration mark (usually black or in a colour that provides maximum contrast to the background) is added to the packaging material.

The goal of any mark sensor development is to reliably detect these registration marks even in changing environmental conditions. A particular challenge is the frequent exchange of packaging materials and the continuously changing packaging designs.

At Omron we closely work together with leading packaging machine makers to evaluate the requirements for sensors from commonly used packaging material as well as most critical designs or materials. In addition the performance requirements vary according to the overall machine value concept
