They use too many different ones, and sometimes it really sucks. I know, Vargas has a hell of a lot more than just blemishes, but I'm talking a blemish that looks like a printed hole in the page! Bizarre.
And Vargas has a bizarre blemish on one of the pages. Some of that is so dark, you can't tell what's going on in some of the panels. That's fine, except for when you have the black and white printing of Miura's watercolors. The interior of the book is printed darker than the Japanese version. I don't know what source material they're using to print from, but compared to the original cover, the Dark Horse cover is blurry, washed out, and looks like ass. The printing is horrible, just like the first cover. Someone needs to fire the graphic designer.
