Every labelled bottle, container, and cup — inspected 100%, automatically, on your production line. Three purpose-built systems covering IML containers, flat bottles, and round bottles with full 360° circumferential coverage.
Labelling errors are the single most common cause of product recalls in the pharmaceutical, food, and FMCG industries. A missing label, wrong label, illegible barcode, or misaligned label is not just an aesthetic problem — it is a compliance failure, a consumer safety risk, and a brand liability.
Labelling and packaging errors are consistently the leading reason for pharmaceutical product recalls globally. A single wrong label on one batch can trigger a market-wide recall and regulatory action.
In a world of 14,000 bottles per hour production speeds, manual inspection cannot reliably catch every missing label, shifted label, or barcode error. Only 100% automated vision inspection guarantees zero-escape.
Round bottles have labels that wrap around the entire circumference. A standard 2-camera front-back system only sees 50% of the label surface. The LIS 360° covers every centimetre of every label — including the barcode, wherever it is.
In-mould labels can fold, misalign, or end up inside the container during the injection moulding process. These defects require specialised inspection immediately after moulding — not at the end of the packaging line.
The Optomech LIS range covers IML containers straight from the moulding machine, flat bottles with front and back labels, and round bottles requiring complete 360° circumferential inspection — all with the same proven machine vision platform.
Purpose-built for IML plastic containers. Integrates directly after the injection moulding machine. Detects label moulding defects that only occur in IML production.
High-speed 2-sided inspection for flat bottles with front and back labels. Detects missing labels, wrong labels, shifting, tilting, barcode errors and more.
Complete circumferential inspection for round bottles. Multi-camera system with image stitching. Detects every label defect anywhere on the bottle surface.
The Optomech IML Label Inspector is designed specifically for plastic containers manufactured with In-Mould Labels — where the label is inserted into the injection mould and becomes an integral part of the container wall during the moulding process. This is common in dairy, food, and FMCG industries using cups, tubs, and containers for products like yoghurt, ice cream, jam, and spreads.
At 5,000 cups per hour, the IML Label Inspector catches defects that are unique to the IML moulding process — defects that would be completely missed by any label inspection system designed for applied labels. The system integrates directly into the production flow after the injection moulding machine.
The LIS 2S is designed for flat bottles with front and back labels — the most common configuration in pharmaceutical, FMCG, and personal care bottling. Running at 14,000 bottles per hour, it simultaneously inspects both the front face and back face of every bottle, verifying label presence, positioning, content, and barcode readability.
The system detects every labelling error that can occur on a high-speed bottling line — from missing labels and wrong-product labels, to subtle issues like label shifting by just a few millimetres or a half-cut label that a manual inspector would miss at line speed.
Round cylindrical bottles with wrap-around labels require a fundamentally different inspection approach. A single camera — or even two cameras — cannot see the full circumference of the label. The LIS 360° uses a multi-camera architecture to capture and inspect every centimetre of the label surface, without exception.
A front-back label inspection system only sees approximately 50% of a round bottle's label surface. Defects on the sides, barcodes positioned anywhere around the circumference, date codes on the back — all invisible to a 2-camera system.
The LIS 360° uses multiple synchronised cameras positioned around the bottle path. As the bottle rotates on the inspection conveyor, every camera captures its portion of the label. Advanced image stitching software assembles a complete 360° map of the label — and the system inspects every pixel.
Bottles are conveyed through the system at production speed on the rotating inspection conveyor.
As the bottle rotates, multiple synchronised cameras capture the complete circumference under LED strobed illumination.
Image stitching software assembles a complete label map. AI-powered algorithms check every defect type against the master reference.
Compliant bottles continue down the line. Defective bottles are ejected pneumatically in real time.
💡 The LIS 360° is ideal for: pharmaceutical syrups & liquid dosage bottles · beverage bottles · water bottles · personal care round bottles · condiment bottles · any cylindrical container with a wrap-around label.

All three LIS systems are built on Optomech's proven machine vision platform — the same foundation used across our vision inspection range for over four decades of industrial deployment.
Industrial-grade cameras with precision optics and customised LED illumination deliver sharp, high-contrast label images at full production line speed — no motion blur, no false rejects from lighting inconsistency.
LED strobed lighting provides precise, consistent illumination across all label materials — gloss, matte, transparent, metallic, and shrink-sleeve. Eliminates reflections and ensures every image is usable for accurate inspection.
Each label image is compared against a master reference in real time. AI-powered algorithms classify defects, minimise false rejections, and maintain consistent accuracy across lighting changes and production variation.
Multiple camera feeds from the LIS 360° are seamlessly merged into a complete circumferential image map — providing a single, unified view of every centimetre of the wrap-around label for defect analysis.
Large-screen touchscreen displays live images of every bottle and container as they pass through inspection. The last 100 defects are shown graphically, enabling operators to spot trends and fix root causes before the problem escalates.
Defective bottles are automatically ejected from the production stream in milliseconds — before they can contaminate the good-bottle stream or reach downstream packaging. Ejection verified by sensor.
Labelling errors are the #1 cause of pharma product recalls. Correct label, batch number, expiry date, and barcode on every bottle is a GMP and regulatory requirement with zero tolerance for errors.
IML cups and containers for yoghurt, dairy, spreads, and food products need accurate label inspection at the moulding stage. Wrong-label incidents in food can trigger safety recalls and brand damage.
Shampoo, lotion, and cosmetic bottles demand brand-consistent, perfectly applied labels. Round bottles in this segment require 360° inspection to ensure the complete label surface is defect-free.
Sauces, condiments, oils, and packaged food products use a mix of flat and round bottles. High-speed production demands automated 100% label inspection to prevent wrong-label shipments to retail.
Vitamins, dietary supplements, and health products carry complex labels with multiple compliance requirements. 360° inspection ensures every element — including supplement facts panels and usage instructions — is correctly applied.
Safety labels on pesticide, agrochemical, and industrial chemical containers are legally mandatory. A missing or wrong safety label is not just a quality failure — it is a regulatory violation with legal consequences.
The inspection screen shows the last 100 defects graphically with images. Operators can immediately identify whether defects are increasing or are caused by a specific SKU or label batch.
Inspection results stored product-wise for complete traceability. Multiple bottle and label configurations stored and recalled by menu selection — fast, reliable changeovers.
Reports exported to Excel with defect counts by type per shift. Auto-schedule reports to be generated and shared over the network at predefined times — daily, per shift, or per batch.
Images of every rejected bottle stored in the database. Recall any image at any time for supplier quality feedback, consumer complaint investigation, or regulatory audit response.
Remote access enables Optomech engineers to diagnose issues, update inspection parameters, and support the system remotely — minimising downtime without requiring an on-site visit.
User, Supervisor, and Administrator roles with separate password protection. All parameter changes are logged — supporting GMP audit trail requirements for pharmaceutical manufacturers.

Everything you need to know about the Optomech Label Inspection System range.
An automated label inspection system is a machine vision system that inspects 100% of labelled bottles on a production line to verify that every label is correctly applied, properly positioned, undamaged, and carries accurate information including barcodes and text. High-resolution cameras capture images of every bottle under LED illumination. Image processing software compares each image to a master reference, detects any defects, and triggers automatic rejection of non-conforming bottles — all at full production line speed without any sampling.
An IML (In-Mould Label) inspection machine is designed for containers where the label is integrated into the container wall during injection moulding. The Optomech IML Label Inspector detects: missing label, barcode reading errors, label folding, spiral misalignment, label moulded inside the container, short moulding, and container contamination. These are defects unique to the IML moulding process — they require inspection immediately after moulding, not during a separate labelling step.
A 360-degree label inspection machine provides complete circumferential inspection of round bottles with wrap-around labels. Multiple cameras capture the entire bottle surface as it rotates. Image stitching assembles a complete 360° view. This is essential for round bottles — a standard 2-sided system only sees about 50% of the label surface. You need 360° inspection if you manufacture round bottles with wrap-around labels, if your barcode can be anywhere on the circumference, or if your product is in a regulated industry where 100% label verification is required on all visible surfaces.
The LIS 2S detects: unlabelled bottles, label applied upside down, label shifting vertically or horizontally, tilted labels, wrong label (wrong SKU or product), half cut labels, double labelling, label folding, and general label errors visible on either face of the bottle. It inspects both the front and back of every flat bottle simultaneously at up to 14,000 bottles per hour.
IML Label Inspector: 5,000 cups per hour (matched to IML moulding machine output). LIS 2S (two-sides flat bottle): 14,000 bottles per hour. LIS 360° (round bottles): configured for your specific production line speed. All systems perform 100% inspection — no statistical sampling.
Yes. All three Optomech LIS systems include barcode reading and verification. The system checks that the barcode or QR code on every bottle is present, correctly positioned, readable, and meets quality standards. Batch code and date code legibility can also be verified — critical for pharmaceutical, food, and FMCG manufacturers where regulatory compliance requires readable and accurate lot numbers and expiry dates on every bottle.
Label inspection systems are used in pharmaceuticals (most common cause of product recalls), FMCG and packaged foods (wrong-label incidents cause costly recalls), cosmetics and personal care (brand integrity and regulatory requirements), beverages (high-speed round bottle lines needing 360° inspection), dairy and food in IML containers, agrochemicals (legally mandatory safety labelling), and nutraceuticals and supplements.
Standard label inspection (LIS 2S and LIS 360°) checks labels applied to already-formed containers — pressure-sensitive, self-adhesive, shrink-sleeve, or wet-glue labels. IML inspection is for containers where the label is inserted into the mould before plastic injection — so the label becomes part of the container wall. IML labels require specialised inspection because defects occur during moulding (folding, misalignment, label falling inside the container) rather than during a labelling step. The Optomech IML Label Inspector is purpose-built for IML production lines.
The Optomech LIS uses a product management system where different bottle sizes, label dimensions, and inspection parameters are stored in the database for each product. Changing from one product to another means selecting it from the menu — the system automatically loads the correct parameters. New products can be added through a guided setup process. This makes the LIS suitable for manufacturers with multiple SKUs and frequent changeovers.
The Optomech LIS provides: real-time display of the last 100 defects with images; database storage of all results for complete traceability; Excel-exportable shift reports with defect classification; automatic scheduled reports over the network; 3-level password access control; and defect image archive for quality audits. These features support pharmaceutical GMP, FDA audit readiness, and ISO 9001 documentation requirements.
Label errors are the leading cause of product recalls. The Optomech LIS catches every wrong label, missing label, and barcode error — on every bottle, every shift, every day.
