Carton inspection for closure, print and product assurance

Inspection overview

Verification from erected carton to finished pack

Carton inspection can be placed at several points: after erection, after product loading, after leaflet insertion, after closure or immediately before case packing. Locating each check where the feature is visible improves reliability and fault diagnosis.

Vision can verify visible flap position, glue pattern where exposed, print, labels, codes and gross damage. Presence sensors or additional cameras can confirm components before closure, with results consolidated into one tracked reject decision.

Checks that can be combined

The final inspection set is selected from the visible features, risk, product presentation and achievable image resolution.

• Carton presence, orientation and colour
• Top and bottom flap position
• Visible glue or closure feature checks
• Artwork and product variant verification
• Label presence, position and identity
• Date, lot, barcode and 2D code reading
• Visible crush, tear or open-carton defects
• Product or leaflet presence before closure

Application details we review

Early clarity on these points helps avoid false rejects, blind spots and mechanical changes late in the project.

• Carton finish, varnish and reflective print
• Open versus closed inspection points
• Variant count and changeover control
• Code location and print technology
• Pack spacing and camera access
• Link to cartoner and reject controls

Place each check where it is most visible

A line review maps every required decision to the best physical inspection point, rather than forcing all checks into one compromised view.

Feasibility work establishes the camera view, lens, light, exposure and image-processing approach. We then define the enclosure, conveyor changes, controls, operator interface and rejection needed for production.
