INDUSTRY • Printing, Film & Web Inspection

A web never stops moving. Inspection can't either.

There’s no discrete “part” on a web line — just a continuous sheet of film, foil, paper, or textile moving at speed, with no natural pause for a manual check. Tech Genesys builds line scan machine vision systems that image the full web width continuously, catching printing defects, alignment drift, surface marks, and material-specific flaws in real time, at the speed the line actually runs.

Web processes give you one continuous surface and no second look.

Unlike discrete-part manufacturing, a web line has no natural stopping point for inspection — the material keeps moving, often at several meters per second, across a width no single operator can watch edge to edge.

No discrete part to inspect

A continuous roll of film or paper has no natural boundary — inspection has to run against a constantly moving surface, not a single stationary object.

High web speeds

Converting and printing lines often run at several meters per second, leaving frame-based imaging prone to gaps between captures.

Full-width coverage

Wide webs need multiple line scan cameras stitched together so no defect near an edge goes unseen.

Repeat, roller-linked defects

Print cylinder and roller defects recur at a fixed interval — spotting the pattern early prevents a full roll being reworked.

Material variety

Reflective film, matte paper, metallized foil, and textured textile each demand a different lighting and optics approach.

Splice & roll changeovers

Splices and roll transitions need to be identified and logged so downstream converting can route around them automatically.

Seven checkpoints across the width and length of the web.

Each checkpoint below runs continuously against the moving material, matched to your web width, material type, and line speed.

Continuous Line Scan Capture

Images the full web width in a continuous strip as material moves, with no frame-to-frame gaps between captures.

Printing Defect Detection

Detects color registration shift, missing or smeared print, ghosting, and print density variation across every repeat.

Web Alignment & Edge Tracking

Monitors web tracking, edge position, and skew to catch drift before it causes wrinkling, telescoping, or off-register printing.

Surface Mark & Contamination Detection

Flags scratches, streaks, stains, holes, and foreign contamination on the material surface as it passes under the camera.

Repeat Defect Detection

Correlates recurring defects to roller or cylinder rotation, identifying tooling issues before an entire roll is affected.

Material-Specific Inspection

Applies defect libraries tuned to film, foil, paper, and textile — from pinholes and delamination to broken threads and moisture marks.

High-Speed Process & Splice Monitoring

Sustains full-resolution inspection at production line speed and flags splices and roll transitions for downstream routing.

Inspection tuned to your web material.

Metallized foil, coated paper, and woven textile each reflect and scatter light differently — we match camera, lighting, and defect libraries to the material.

Printed Packaging Film

Registration, color, and surface defect inspection on flexible film.

Metallized Foil

Pinhole, gauge band, and reflectivity-aware surface inspection.

Coated & Uncoated Paper

Tear, wrinkle, moisture mark, and print quality inspection.

Nonwoven & Textile Webs

Weave defect, broken thread, and dye variation detection.

Laminates & Multi-Layer Films

Delamination and layer-alignment inspection across bonded structures.

Labels & Pressure-Sensitive Stock

Die-cut accuracy and print quality inspection on label webs.
