Movie poster questions?

[Jasonic]

I'm no poster aficionado, so these might sound like amateur questions. I'm trying to deck my room out with a bunch of 40 x 27 posters. About 10 of them. I have no need for originals, definitely not paying those prices. But why are so many reproductions badly done? Not all of them are and I guess it depends on who does it, but I've gotten a couple where the the colors have a faded and dark tint to them. I assume this is a reason so many people care about originals. I also assume it's why these are cheap to produce, but why? I don't know anything about printing, but I just don't understand why it would be so much more expensive to get the colors right. And if that is really all it is, then why don't I see more expensive reproductions being sold, that are of higher quality?



Also, most posters are easy to find, but why do they not make reproductions of certain ones? Can't find this one anywhere.
