**Q: how deep is it? The bottom bar is less deep than the top bar; how deep is the top bar? across the bar not end to end**
A: how deep is it? Not very deep
The bottom bar is less deep than the top bar? It is the same bottom and top
 how deep is the top bar? You can run your figure across the the engraved and feel that it is raised up

**Q: Are the markings along the ruler printed or engraved?**
A: They are printed/painted on, the people who are saying "engraved" are probably feeling the thickness of the paint. The paint job is quite poor on mine, I see the same defects on the seller's photos, just fewer of them.
