Vision Intelligence for Sheet Inspection on Print Lines

Embedded precision inspection for press OEMs and machinery integrators — turning inspection into a built-in capability, not an afterthought.

Sheet Inspection on Offset Press
Overview

YantraVision's Sheet Inspection System is an OEM-integrated machine vision solution that embeds AI-powered precision inspection directly into print presses and finishing machinery. Operating at full production speed with no line slowdown, it performs 100% inline inspection of every sheet — detecting print, colour, coating, die-cut, and substrate defects below 0.1 mm using multi-camera synchronised capture.

The result: every sheet leaving the press has been inspected — catching print, colour, coating, punch, and die-cut defects before they reach the customer. Built for press OEMs and machinery integrators where adding inspection capability is a competitive differentiator.

What matters is Yield Control

High detection sensitivity alone does not make a production system work.

YantraVision's inspection software gives operators and QA teams configurable control over accept/reject decisions — with defect severity classification, tolerance thresholds, and zone-based rules tunable per job.

The operator defines which defects are critical and which are acceptable for a given job. This job-level sensitivity control is what drives high yield — compliant quality is maintained, while defined defects are reliably eliminated. The same engine works across different press types and substrate families.

The result: compliance-grade inspection with production-grade efficiency.

How It Works
Machine-Integrated Mount
Machine-Integrated Mount

Camera heads, strobe lighting, and compute modules mount within the press — factory-aligned during commissioning. No separate cabinet, no extra floor space.

Sheet-by-Sheet Capture
Sheet-by-Sheet Capture

Every sheet imaged at full press speed — front, back, and surface finish in one synchronous pass. Slaved to press encoder signals for precision at any speed.

AI-Driven Classification
AI-Driven Classification

Deep learning classifies defects in under 30ms per sheet — separating real faults from acceptable substrate variation. AI-assisted job setup auto-configures tolerances from the approved master.

Accept / Reject Output
Accept / Reject Output

Integrates with the machine's PLC — triggering diverters, line-stop events, or marking systems. Clean sheets proceed; defective sheets are flagged or ejected per sheet.

OEM Partnership

YantraVision supplies the complete inspection stack — illumination design, optics, imaging hardware, and AI compute — as an integrated, OEM-ready system. The partnership is an ongoing engineering relationship: co-development of mounting configurations, PLC integration protocols, and inspection parameter libraries specific to each press model. Each generation carries accumulated engineering depth forward.

Frequently Asked Questions
❓What is YantraVision's sheet inspection system?▼
YantraVision's Sheet Inspection System is an OEM-integrated machine vision solution that embeds AI-powered inspection directly into print presses and finishing machinery. It performs 100% inline inspection of every sheet at full production speed — detecting print, colour, coating, die-cut, and substrate defects at below 0.1 mm resolution.
❓How does sheet inspection integrate with print presses?▼
Camera heads, strobe lighting, and compute modules mount within the press — factory-aligned during commissioning. No separate inspection station or additional floor space required. The system slaves to press encoder signals for precise synchronisation at any speed, and integrates with the machine's PLC for automated accept/reject decisions.
❓What defects does the sheet inspection system detect?▼
Four defect categories: print and colour defects (missing print, colour deviation, registration error, hickey, ghosting, smear), coating and surface defects (uneven coating, streaks, bare patches, lamination bubbles), punching and die-cutting defects (mis-punched holes, misregistered cuts, incomplete cuts, Braille verification), and substrate/back-face defects captured by a dedicated underside camera.
❓Does the system slow down the press?▼
No. The system operates at full press speed with no line slowdown. AI classification processes each sheet in under 30ms using deep learning that separates real faults from acceptable substrate variation. Multi-camera synchronised capture ensures complete sheet coverage without affecting cycle time.
❓What industries use sheet inspection?▼
Primarily pharmaceutical packaging (folding cartons for blister packs, bottles, and sachets where every print element carries regulatory weight) and commercial print (high-volume sheetfed offset runs where brand colour consistency and zero-defect delivery are required).
❓How does AI classification reduce false rejects?▼
The AI engine provides job-level sensitivity control — operators define which defects are critical and which are acceptable for each specific job. Defect severity classification, tolerance thresholds, and zone-based rules are configurable per job. This yield control approach maintains compliance-grade inspection while maximising production efficiency.
