Strange things. Can anyone explain?

I will have to get a picture of this later but for some of my scans with either the turn table or the free scan I get two characteristics:

1. Wavy lines. Like there are grooves in the objects or my face (tried a face scan). It happens more on difficult shapes.
2. Bolding letters. I have seen this happen to other users. Is it just me or when there is fake 3d bolded text on a product the scanner thinks it is raised? I have tried this several times with a bottle of Titebond II wood glue. It's weird that the lettering would be bossed out like that.

Hello!
did you find any solution to the wavy lines?
I'd not figure it out how to prevent those to appear. attached is an example of the wavy lines?

does anybody knows why these lines happened?Screen Shot 2015-11-04 at 8.36.22 PM.jpg
