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.
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.
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.
Converting and printing lines often run at several meters per second, leaving frame-based imaging prone to gaps between captures.
Wide webs need multiple line scan cameras stitched together so no defect near an edge goes unseen.
Print cylinder and roller defects recur at a fixed interval — spotting the pattern early prevents a full roll being reworked.
Reflective film, matte paper, metallized foil, and textured textile each demand a different lighting and optics approach.
Splices and roll transitions need to be identified and logged so downstream converting can route around them automatically.
Each checkpoint below runs continuously against the moving material, matched to your web width, material type, and line speed.
Images the full web width in a continuous strip as material moves, with no frame-to-frame gaps between captures.
Detects color registration shift, missing or smeared print, ghosting, and print density variation across every repeat.
Monitors web tracking, edge position, and skew to catch drift before it causes wrinkling, telescoping, or off-register printing.
Flags scratches, streaks, stains, holes, and foreign contamination on the material surface as it passes under the camera.
Correlates recurring defects to roller or cylinder rotation, identifying tooling issues before an entire roll is affected.
Applies defect libraries tuned to film, foil, paper, and textile — from pinholes and delamination to broken threads and moisture marks.
Sustains full-resolution inspection at production line speed and flags splices and roll transitions for downstream routing.
Metallized foil, coated paper, and woven textile each reflect and scatter light differently — we match camera, lighting, and defect libraries to the material.
