Print flaw and variety

If you find 2 identical it is a variety, if not you can't proof it is one.

I'd separate "printing flaws" into two categories: plate flaws/varieties and printing flaws/varieties. Plate flaws are some defect of the printing plate itself, and occur on all sheets in at least a part of the print run. Examples are things like the "dot" on Russia No.1, the "SESR" on the 1928 Red Army 28k value, etc. It's a fine line between "flaws" and "varieties" there, but they are constant.

There are also incidental flaws, which might be the result of, say, a piece of dirt on the printing plate. They're more "freaks" then flaws.

Then there are printing varieties, which occur as a result of some defect in the printing process itself. Inverted centers are printing varieties, for example. Almost by definition these occur on one sheet only, unless the printer was very sloppy, so in a way, all printing varieties are "freaks."

What's your take in regards to color?
sometimes terms are too loosely traded - variety, error...

Color's a tough one, since it often is a function of both ink and paper: different shades are often the result of the paper used, as collectors of RSFSR stamps know.
For the same paper and the same printing method, true identifiable shades are usually from different printings. I wouldn't call that a variety or error. A real color error that does not fall into any of the categories above is pretty scarce in Russia. The 70 instead of 100 RSFSR stamp is the only example I can think of, and that is actually a plate variety rather than a color variety...
