Paint on build sheet

Just received the printer! Really easy setup and operation. Prints are excellent so far. One or first compliant is the paint on the build sheet. Why is it painted? If it is just for looks, then save the $$ send the plate with your name on it only please. The corner markings are probably ok.

I had a spare of the same size but with no paint and have installed that. But don’t want to have to buy a plate just to not have the paint. Is there a safe manner in which to remove the paint?

Others with similar thoughts?
