VDI 3400 Surface Texture VDI18

Textured plastics are often controlled using visual/tactile comparison to texture card samples like this one:

This texture card is based on the VDI 3400 texture reference, which is used for controlling the surface finish of injection molds and the plastic parts they generate for applications in automotive, aircraft, electronics, and consumer goods. Other, similar finish references include SPI, Mold Tech, and Yick Sang.

This dataset is a measurement of the VDI 18 surface on this texture card. Which parameters can you find in OmniSurf3D that differentiate this surface from the other surface textures on this card?

Measured via Zygo ZeGage Plus (10x), desampled 2X
