Universal, GMP-Compliant Label Inspection for Pharma, Medtech & Food
UELI is a universal, GMP-compliant label inspection system that ensures flawless labels and full traceability. It automatically verifies text, codes, and graphics, reducing errors and waste while maintaining compliance. Designed for seamless integration into existing printing processes, UELI is ideal for pharmaceutical, medtech, food & beverage, cosmetics, and chemical industries, delivering reliable quality control and peace of mind.
Benefits for your company

Adaptable by design
UELI fits into your environment: a height-adjustable inspection station with matrix camera and illumination and an industrial panel PC running QualiReader inspection software. You intend to retrofit your existing print equipment with a vision inspection or you want to build a compact table-top printing cell and you bring the label printer and rewinder. UELI verifies pre-printed elements, codes, text, symbols and variable data so that good labels keep moving and bad ones are stopped.

Digital reference, less setup
UELI works with a digital reference either manually imported or directly from your LMS/ERP via Level 3 or Hotfolder. When the LMS/ERP supplies the digital reference with meta data such as field definitions and formats, QualiReader automatically selects the appropriate inspection method and parameters for each relevant print area. If a digital reference is not directly accessible, simply import a picture or PDF to get going quickly.

Built for your process
Image capture synchronizes to the printer via I/O, ensuring consistent inspection at speed. Orders and articles are managed on the system and can be operated via touchscreen, order sheet (code scanner) or remotely. Results are stored locally on the IPC and can also be mirrored to your database, LMS or ERP for traceability.

Results you can trust
Legibility of static or variable content is checked with PrintControl; codes are read and compared with order data (and optionally classified with a grading approximation); serialized text fields can be verified with OCR/OCV. Out-map masking excludes non-relevant areas to keep performance high and false rejects low.
How UELI works (can be adapted to the customer's process)
- Import the layout. Pull the digital reference from LMS/ERP via Level 3, or import a picture/PDF reference manually.
- Automatic teach-in. Knowing what is printed, where and in what format, QualiReader selects the optimal method per print area and sets the image-processing parameters automatically.
- The matrix camera and illumination capture each label; printer I/O triggers image capture and controls the feed.
- Decide on non-OK labels. If the printer supports overprint voiding and I/O control, UELI voids the label automatically. Otherwise, the job pauses; the operator removes the faulty label and confirms in QualiReader.
- Document the outcome. Results are stored on the IPC per order/article with pass/fail and statistics, and can also be written to your IT systems (database, LMS or ERP).
PrintControl: GMP‑grade legibility, by design
PrintControl is a geometry‑based, layout‑driven inspection algorithm for static text, logos and artwork. Using the digital reference, it decomposes characters into vector strokes and checks them line by line—delivering an explainable, GMP‑grade legibility score without manual teach‑in. It handles complex scripts (e.g. Arabic, Chinese, Japanese) and touching characters (e.g., “VV”, “Qj”), lets you tune sensitivity per area, and reduces false classifications for faster setup and better auditability.
Hardware in one station.
A height-adjustable mount with alignment guides for fast centering, a matrix camera with matched illumination, an I/O interface for printer trigger and feed, and an industrial panel PC running QualiReader I. You supply your preferred printer & rewinder, so the cell mirrors your current process without any unnecessary re-engineering.
