The Objective Eye for a Brilliant Finish
Surface appearances change with the size and distinct- ness of structures. Structures will be perceived as being very distinct, if e.g. an edge is reflected on the surface with high contrast and sharpness. The wave-scan DOI evaluates structure size as well as the brilliance of the surface.

Peel and DOI measurement on high to semi gloss surfaces
… appearance control is no longer limited to final topcoat inspection.
Like the wave-scan DOI, the optical profile of high gloss surfaces is detected
using a laser light source. An additional, infrared - high energy LED
allows measuring the same structure spectrum (0.1 - 30 mm) on medium gloss
surfaces.
The dullness measurement is recorded with state- of-the-art CCD camera
technology. It gives information on the image forming qualities of the
surface caused by structures < 0.1mm.
Close the appearance control loop for the entire paint process
Thus, the surface quality after each paint process step can be objectively
evaluated. No more guessing which substrate layer is influencing the
final appearance. The wave-scan dual will help you to objectively analyze
appearance problems and reduce the time necessary
for trouble shooting.
Example: Influence of Steel Quality on
Final Appearance
Same E-coat system was applied on rough and smooth steel. The influence of rougher steel can be seen in increased Wb and Wc-values.
The primer surfacer was applied on both panels. The roughness of the steel quality can still be detected in increased Wb and Wc- values. This primer system could not completely cover the steel influence.
The final appearance shows higher shortwave values on the rougher steel panel. Therefore, the smooth panel will appear more brilliant.
Now, you can establish appearance specifications for each paint layer to ensure the final appearance is always on target.
