Read every printed character, date and code on your line — automatically, at full production speed. Unreadable expiry dates, wrong lot codes and unscannable 2D codes are a recurring source of recalls, rejected pallets and customer complaints. 3HLE builds OCR and code-reading systems with Retina A.I. Vision that verify each mark as parts go by, so nothing leaves the line with a missing, illegible or incorrect code — and your operators are freed from staring at print quality all shift.
What 3HLE reads on your line
Expiry & lot/date codes
Best-before, production date, batch and line IDs — verified for presence, legibility and correctness on every unit.
Characters & variable text
Alphanumeric print on labels, caps and bodies, including changing content between batches.
1D / 2D codes & DataMatrix
Barcode and DataMatrix presence and grade — catch codes a scanner would later fail to read.
Print-quality & traceability
Smudged, faint, double or shifted print flagged before it reaches your customer — full unit-level traceability.
Hard surfaces, fast lines — handled
Most reading failures happen where ordinary readers struggle: shiny metal, curved cans, transparent PET, low-contrast or fast-moving products. These are exactly the conditions 3HLE systems are built for. A few real examples from production:
- Reading dates & line IDs on shiny, curved aluminium cans
- Reading characters on PET bottles at production speed
- Setting up an industrial OCR application with a 99.99% read rate
- Deploying a high-speed OCR tool onto a production line
- Showcase: high-speed OCR on curved aluminium cans
- Showcase: OCR on a live production line
How it works — in plain terms
You show the system a handful of sample images of your codes; it learns to read your characters and marks — no programming, no rule-writing. It then runs locally on industrial hardware, 24/7, beside the line — no cloud, no production images leaving your site. When a code is missing, illegible or wrong, the part is flagged or rejected in real time. As your packaging or print changes, the system is retrained in minutes by your own team.
Why deciders choose it
- No human-factor errors — every unit checked the same way, every shift.
- Fewer recalls & rejected shipments — bad codes are caught at the source, not at the customer.
- Full traceability — proof that each unit carried a correct, readable code.
- Skilled staff freed from manual print-quality checking.
Common questions
Can it read on shiny or curved surfaces? Yes — reflective metal, curved cans and transparent bottles are the typical use case, not the exception.
How fast can it read? At line speed; the showcases above run on real high-speed production lines.
Do we need an in-house specialist? No — your team retrains it from a few images when print or layout changes, with no code.
Does our product data leave the site? No — it runs locally next to the line.
Have a code or character you need read reliably? Send us a few sample images and we will run a preliminary read test on your actual parts. Contact 3HLE.
