| Orange 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 |
| Step 1: Appearance Control after E-coat | Step 2: Appearance Control after Primer Surfacer |
 |
 |
| 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. |
| Step 3: Appearance Control after Topcoat |
wave-scan
dual – a diagnostic tool for trouble shooting and optimizing appearance
Now, you can establish appearance specifications for each paint layer to ensure
the final appearance is always on target. |
 |
|
| The final appearance shows higher shortwave values on the rougher steel panel. Therefore, the smooth panel will appear more brilliant. |
| Objective and reliable appearance data |

Always ready |
| The instrument
is operated with a rechargeable battery pack (Li-Ion). The docking station automatically
charges the battery pack and transfers the measured data to the PC. Optionally, the instrument can be operated with 3 standard mignon alkaline or rechargeable batteries - good for 1000 readings. |
