Wintriss Camera Architecture

Competition in the web processing industry is stiff, and the demands are constantly on the rise. Exact control of the qualities of the outer surface is a prerequisite for defect-free printing products – and for satisfied customers. Here, BST eltromat offers effective support with intelligent systems for 100% quality control during production.


Surface inspection systems provide information on the substrate’s outer surface quality, so that consistently high quality is guaranteed in the subsequent production steps.

Wintriss Inspection Solutions, Ltd., a subsidiary of California-based Wintriss Engineering Corporation, develops and manufactures optical surface inspection systems using smart, CCD line-scan cameras. Rapidly expanding and with a world-wide presence, Wintriss has installed over 250 inspection systems in North America, Asia, and Europe. Wintriss Engineering is a pioneer in embedding processing intelligence in cameras. After introducing 1st Smart Camera in 1994, we have created increasingly capable cameras with greater processing speed, higher resolution, and standout flexibility, specifically adapted for web and other types of surface inspection applications.

Wintriss Inspection Solutions’ flagship product is the Web Ranger System, which employs the linear cameras in a network-based, distributed architecture. Our core competency is the in-depth understanding of optics and image processing. This expertise and our surface inspection experience enable the company to conceive and implement innovative designs to meet diverse customer requirements for surface inspection. Key patents in image processing and illumination technology are the basis for the exceptional defect detection capability of the Web Ranger System and Wintriss’ market leadership in the inspection of display films.

Application and Defects Detected

Applications: 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. The scope for Wintriss “Web Ranger System” has broader application and it is suitable for wide range of materials:
