KHEOPS — Mottling & Surface Roughness Measurement
KHEOPS is a laboratory sensor for print mottle and surface roughness evaluation, designed for papermakers, board makers, ink manufacturers, coating suppliers, and printing operations. It delivers accurate, repeatable results that correlate closely with human visual assessment.
What it measures
- Print mottle quality on offset impressions.
- Coating application precision.
- Substrate roughness (paper, board, and other flat materials).
The instrument is highly sensitive to changes in mottling or smoothness and provides practical, responsive measurements for routine QA.
Why it’s reliable
- Excellent correlation with visual inspection and excellent linearity.
- Perfect repeatability of the measurement algorithm.
How it works
- Imaging & illumination: CCD camera with lens close-loop control, two light sources with diffuse light for printed mottling and 8° incident light for roughness.
- Stable illumination during capture and processing; < 1 second for an individual analysis.
Software at a glance
- Measurement window: six reference windows; configurable results table.
- Configuration: the final Mottling Index combines five preset size classes.
those classes can be customized by user - Outputs: average mottle or smoothness, inter-measurement deviation, tolerance thresholds, class distribution, and class-distribution SD.
Technical Specifications
- Sampling area: 25×25 mm or 12.5×25 mm; max sample thickness: 4 mm.
- Operating system: Windows®.
- Power supply: 220V/50 Hz or 110V/60 Hz, 50 W.
- Dimensions (W×D×H): 370 × 370 × 400 mm.
- I/O: video output and regulation input; Gigabit interface with cables.
In Summary
KHEOPS provides fast (<1 s), repeatable evaluation of print mottle and surface roughness, using robust optics and stable illumination with software that outputs actionable indices and class distributions for process and quality teams.
