Kheops - Mottling measurement sensor

 

 

The Kheops is a laboratory sensor designed to easily provide accurate and repeatable evaluations on :

  • Quality of offset impressions, print mottle, and the quality of coating application
  • Paper, Board or other flat material surface roughness
  • White top board quality evaluation

The Kheops has been specifically designed for papermakers, board makers, ink manufacturers, coating suppliers and printing operations.

 

User Friendly Software

The Windows software has been developed by CTP and TECHPAP engineers in conjunction with industrial users to be efficient in operation, easy to use and versatile. To make a test, the operator simply places the sample in the system, enters the sample reference and clicks on the area to be tested.

» The result output includes the average print mottle or surface smoothness plus deviation between measurements, tolerance threshold, class distribution and class distribution standard deviation.

 

Kheops Practical, Repeatable and Responsive

The Kheops sensor is essentially a CCD camera and two specially designed light sources (a diffused light for print mottle analysis and a low angle LED lamp for surface smoothness evaluations). The housing has a small hinged door on its front side to introduce samples for testing.

The camera and lighting system is automatically adjusted to maintain a stable sample illumination during the image capture measurement process. The Kheops uses a PC to automatically set the camera, analyze the images, make calculates, display the results, memorize the results and send the results to the DCS or Data Historian.

The Kheops sensor is very sensitive to mottle or smoothness changes in the paper. The repeatability of the system is exceptional and the results have been closely correlated with visual tests.

The final mottling index is the result of the combination of 5 individual class size categories. These 5 class sizes can be preset by the operator depending on the application requirements.

 
  • All results are stored on the PC and can be transferred to any spreadsheet or data historian.
  • Operational icons are easy to understand and there are 6 test reference windows plus a window for comments.
  • All class size parameters, luminosity levels and formula parameters can be adjusted and set.

 

 

RESULTS

  • Excellent correlation with human eye evaluation and sensitivity
  • Excellent linearity
  • Excellent repeatability
  • One single number index between O (ideal sample) and > 100
  • Index number is the result of 5 individual categories of class size Minimum class: 0.5 to 1 mm
  • Size and highlight of each class are selected by the operator in order of importance
