Roll-to-Roll Manufacturing
Roll-to-roll manufacturing operates at high speed where quality defects can propagate across thousands of metres of material before they are detected. Machine vision provides real-time, 100% inspection at full production speed — detecting print defects, surface contamination, coating issues, and dimensional variation. Combined with defect data management and smart converting, vision systems transform quality from a reactive cost into a strategic advantage.
Machine vision applications
Key areas where machine vision delivers measurable value in roll-to-roll manufacturing manufacturing.
Web and surface inspection
Full-width defect detection for film, paper, foil, and non-woven webs. Line scan cameras with precision lighting detect gels, contaminants, holes, streaks, and coating defects at production speed.
Print inspection
Automated print quality inspection for flexographic, gravure, and digital printing. Repeat-length comparison, colour monitoring, and barcode verification on flexible packaging.
Label converting inspection
Inline inspection of labels for print defects, die-cut accuracy, missing labels, matrix waste, and variable data verification. OEM-ready solutions for machine builders.
Coating and lamination verification
Verify coating presence, uniformity, and edge position using UV, IR, or visible light imaging. Detect adhesive voids, coating gaps, and registration errors.
Width and dimensional measurement
Non-contact measurement of web width, lane positions, seal widths, and edge profiles. Continuous measurement data for closed-loop process control.
Roll tracking and waste removal
Digital roll mapping with automated waste removal on the unwind. Track defects through multiple processes and remove at the final operation to maximise yield.
