Those test painted plates are made by K. Ishi. The sizes of them are 3 x 8 cm ^2 .

We find here the less the surface registivity the smaller the granuarity.
The depth of the holes (this means almost the thickness of the carbon paint) is around 5-7microns.
The size of the holes depends on the surface registvity as described above. Measurement is carried out on the red line and the results are shown as a green line in the picture.
The 3-D pictures are in the same magnification.
