Technology We Stand by

Tested and proven hardware: The ColoXRA Family.

  • Ambient light, web speed, and normal flutter have no effect on the accurate measurement results.
  • The instrument is robust, splashwater-tight (IP65), and only needs minimum maintenance.
  • The long-life Xenon flashlamp (1-year warranty) is inexpensive.
  • Multiple displays of measurement results.
  • Base color and optical brighteners are measured separately. Therefore, both components can be controlled independently.
  • Same as in lab: Stable color measurement data even when basis weight changes. Only the opacity changes.
  • Excellent results with a spectral resolution of 1nm.
  • Alarm signal, link to QCS, PI, and MOPS systems.

Improve Color Quality with Inline Color Management

Designed to meet the requirements of industrial paper and plastic environments, the industry-leading, non-contact ColorXRA 45 inline spectrophotometer measures color on a variety of paper and plastic materials where color is critical, including those with textured, finely patterned, and glossy surfaces and with optical brightening agents. When used with ESWin Closed Loop Color Control software, the ColorXRA 45 enables precise and automatic color adjustments to reduce rework caused by color variations and increase production output.

Enables Fast, Automatic Control for a More Stable Production Environment

The ColorXRA 45 is mounted on a custom frame over the production line at the correct distance to detect even the smallest color deviations. When paired with ESWIN Closed Loop Color Control software, color corrections are carried out automatically, and dye adjustments can be calculated in one step. ColorXRA 45 removes the guesswork around color control for less waste and rework and a fast ROI.

Correlate Lab Data

Minimizes Color Variations and Rejections

With standardized 45°:0° measurement geometry and spectral resolution of 1 nm, the ColorXRA 45 maintains tight color tolerances throughout production without cutting a sample. Temperature and dirt detection sensors warn of issues that could impact the final color. Base color and optical brighteners can be measured separately for optimal control over each component for stable measurements even when base weight or opacity change.

Objective Color Evaluation

Records and stores all color quality documentation for future evaluation according to ISO 9001. 


Excellent Short- and Long-Term Stability

Uses dual beam measurement and automatic wavelength calibration to ensure exceptional measurement accuracy and stability. 


Maximum Uptime and Reliability

Ambient light, web speed, and normal flutter do not influence measurement accuracy, and external calibration is only required every four weeks.
