## Question

When should I use a Roll-2-Roll sensor instead of a full machine vision system?

## Short Answer

When you need vision-like inspection — splices, flags, tears, thread counts — but a camera-based vision system would be overkill for the application.

## Detailed Answer

When you need vision-like inspection capabilities but a camera-based machine vision system would be overkill for the application.

Machine vision systems excel at complex pattern recognition and two-dimensional image analysis, but they require programming, calibration, controlled lighting, and a vision expert to deploy and maintain. Roll-2-Roll® sensors fill the gap for applications where **spatial awareness matters but full 2D imaging is unnecessary**:

- Splice detection — identify tape splices, overlaps, and joints in real time
- Flag detection — detect operator flags and registration marks with a 48 mm sensing window (vs. 2–8 mm for conventional mark sensors)
- Tear and void inspection — detect holes, tears, and surface anomalies across the web
- Multi-strip width monitoring — measure multiple strip widths and gaps simultaneously
- Thread counting — count individual threads or strings

Roll-2-Roll® sensors deliver these inspection capabilities with zero programming, zero calibration, and setup in minutes — making them the practical choice when traditional sensors are not enough but a full vision system is more than you need.
