Surface Inspection, Precise Defect Classification

Web Ranger - Surface Inspection System

Easy to use tools and simple system setup
Higher product quality, better yields and lower costs of production

The Web Ranger is an optical surface inspection and defect classification system that provides a total quality solution for products produced in continuous webs.

The highly modular design allows the system to be tailored to any application based on web width, web speed and defect size (resolution) requirements. The incorporation of smart cameras with embedded processing resources enables the system to provide real time, 100% inspection of the material and rapid, accurate detection of defects.

Precise Defect Classification

The Web Ranger’s advanced surface inspection classification engine can perform precise defect classification based on extremely subtle differences between defect categories. Using over one hundred extracted features and multiple techniques, the classification engine can be easily trained to reliably recognize distinct defect categories present in the material being inspected. Web Ranger’s superior classification performance greatly enhances product grading, process control and overall quality control.


Advanced Classification

precise classification of defects into user-defined categories using advanced statistical (KNN) and non-linear heuristic methods (neural networks)

SQL Database

comprehensive database of defects with images, positions and all defect features

Automatic Archiving

automatic transfer of defect data to an external device or system based on user-defined criteria

Flexible Reporting

standard and custom reports of inspection results and statistics in tabular and graphical format

Trend Analysis

automatic detection and reporting of repeating defects

Formation Analysis

Graphical display of product quality based on calculation of a Non Uniformity Index

Defect Density

automatic defect monitoring based on user-specified criteria that assign points to defect class occurrences

Roll Grading

automatic grading of rolls based on user-specified grading criteria that assign points to defect class occurrences

Custom Digital I/O

to generate alarms, trigger marking and tagging systems, automatically start/stop jobs, etc.

Multi-Language GUI

English, German, Chinese, etc.

Factory Interfaces

Windows-based open architecture allows easy connections to other systems and devices via OPC, SQL Query, Ethernet, or custom digital interface


Remote access via Internet for system maintenance and software upgrades


24/7 Technical Support via Internet and Telephone Hotline



The incorporation of smart cameras with embedded processing resources enables the system to provide 100% inspection of the material and rapid, accurate detection of defects. This allows the system to be easily optimized to inspect metallized plastic film, synthetic paper, fiberglass, woven textiles, coated nonwovens, glass and many more.

Web Ranger inspection solutions and classification libraries have been successfully proven for many industries.


for Surface Inspection Applications

High-Intensity Illumination

Wintriss linear light sources are optimized for web inspection and the challenge of operating in a 24/7 production environment:

  • High intensity to 100,000 lux
  • Superior reliability up to 100,000 hours
  • Modular for any width web
  • Outstanding uniformity for consistent detection
  • Wintriss patented lighting products are the most advanced in the industry. Our Sodium Vapor and LED linear lights are specifically designed for web inspection applications:
  • HP Sodium Vapor – high intensity front light
  • LED Ranger (LED) – high intensity front or back light available in multiple wave lengths and intensities, diffused or focused
  • Refraction Ranger (LED) – collimated light for translucent materials

Whatever your surface inspection application, Web Ranger is a cost-effective solution that provides a rapid return on investment.

Compact, Energy-Efficient Lightsource

Proper illumination is critical to effective flaw detection performance. Lighting design must consider material texture, web speed, defect size and type, color and ambient lighting.

Wintriss lighting experts have developed and patented a series of sophisticated techniques and specialized lights that are optimized for surface inspection. We are the best in the industry at determining the most effective lighting solution for the inspection application. Wintriss has patented several innovative lighting techniques that expose extremely small defects that can't be detected by other systems. The clarity of the images produced using these techniques results in reliable detection and accurate classification.

  • Modified Schlieren for plastic film and glass
  • Bi-Level Lighting for 3D defects in metal, film and glass


A powerful classification engine quickly and accurately sorts the defects into user-defined categories to aid in production quality control and process improvement. All defect data can be viewed in real time and is also stored in a comprehensive database for subsequent review, analysis, reporting and archiving.
