Tissue Paper

Surface Texture of Tissue Paper - Digital Metrology

This is a sample of regular, household tissue paper. 

Compare the image above to the image of printer paper, also in this library:

They look very similar, right? But if you look at the z-axes of both plots, the vertical scale of the tissue paper is almost 10 times larger. When you display basic height parameters such as Sa, the difference jumps out: the Sa of the tissue paper is ~25µm, while the Sa of the printer paper is only ~3µm.

To properly display data for comparison,  the vertical axes must match. Double-click the Z (vertical) axis in the data plot, then enter the same ranges for both datasets. Here are the two datasets again, side by side, with the same vertical scales applied to each:

By the way, did you know that you can run more than one instance of OmniSurf3D at the same time? Once you have a dataset open in OmniSurf3D, double-click another dataset in Windows (if you have file associations set), and it will open in a new instance! If you don’t have file associations set, simply right click on the OmniSurf3D icon on the task bar and open another instance via the popup menu.  This is a great way to compare data side-by-side.
