Ink transfer, and grades.

[B-Smooth]

I have several Secret Wars 8's, and they are all super high grade. In these 2 pics, you can see where the green has lightly transferred onto the white back cover. I've seen this on numerous occasions, in different collections, with all different storage, and it seems to be a common ocurance. Do you see this kind of thing often, and is this something that detracts from its grade if it's some kind of production flaw? Here's the 2 pics.

and the offending green paint...

Any help would be great. My opinion is that it is inevitable, and like printing defects, should be allowed on 9.9's-10.0's. (not that mine are that nice.)

Looks like I got a partial answer. This pic is from a SS 9.8. It appears to be identical to the ones on my books. The question now is whether or not a 9.9 or 10.0 is possible? There are a couple on eBay, but I can't see the back cover well. Anyone here have one? There's 19 of them, so it shouldn't be that difficult to find one. Thanks.
