How do I sense a registration mark on clear material?
Clear materials (e.g. a clear poly web) don’t reflect light very well, so when sensing a registration mark on a clear material, position a reflective surface directly behind the clear material to return light to the R58E. The registration mark will block the light from reaching the reflective surface and will be detected by the sensor. To avoid the shine from clear materials, you might consider mounting your sensor at a 15° skew angle.
