Crane Currency, which produces the paper on which the United States government prints its currency, passports, and other government documents, enlisted the help of Boulder Imaging to install a vision system which could inspect its production line.

Boulder Imaging installed its SPX Series inspection system, which is an inline system that detects defects of non-uniformities in printed web materials. It enables the segregation and categorization of defective parts and materials on a production line and allows of the implementation of stop-points in production to allow the production manager or process engineer to identify and correct problems in real time. It automatically analyzes printed sheet samples for surface irregularities and imbedded contamination down to 10 µm at full line speed.

Crane’s previous vision system had production lines running at 250 feet per minute, averaging six false positive per hour, requiring them to shut down the lines to review the false positives. With the SPX Series system, Crane found that inspection speeds increased from 250 feet per minute to 750 feet per minute, and the occurrence of false positives fell from six per hour to one per every 48-64 hours.

Boulder Imaging also recently announced the release of three new products showcasing technology for metrology, surface inspection, and digital recording:

  • The SCL Series offers advanced surface inspection in a fully automated computer-based defect classification system for automotive and performance coatings.
  • Boulder Imaging’s ML Series offers a high speed metrology system which enables the measurement of multiple high-precision, 2D, flat parts for parts manufacturers.
  • The Quazar is a digital video recording, processing, and analysis solution which make engineering and scientific observation, measurement, and review of critical events possible in real time.
