Roll Gauge
This application is for Large Format Printer users. Measure your roll media by taking photos of your new and used rolls. Calibrate the process with the new unused rolls and after usage just take a photo of the calibrated roll and we calculate the length of the rest on the roll. We can only promise a precision somewhere of +/-1.5 m.
Future developments:
-after 50 downloads - more accurate algorithm possibly precision +/- 0,5 m
-after 100 downloads - Can i print X copies of X by Y size on my roll? -calculator
