On the other hand, if you look at the Batman Illustrated by Neal Adams volumes from DC, Adams was allowed to recolor all of his work for the hardcover treatment. While the paper the company chose for printing has a softer, more matte-like finish, the artwork at times looks a bit muddy. I've seen several reviewers and bloggers bemoan the notion that they entertained a re-do by Adams on any aspect of the art.
Then there's the re-issue of Stan Lee/Jack Kirby's Tales of Asgard in hardcover format, completely recolored using modern computer techniques. I don't think Kirby's art was ever meant for a color palette that bold and varied! I've located some various examples from newsprint, Marvel Masterworks, and the aforementioned Tales... HC for your examination.
Lastly, the Marvel Essentials and DC's Showcase Presents offer lots of bang for your buck -- almost 25 comic reprints per volume -- but all in black and white.
So, what do you think about "updating" the coloring, whether through modern printing techniques or just heavier, glossier paper? Do you like the tpb's that are basically the original newsprint with a new cardstock cover slung around? Certainly durability is an issue when purchasing a tome that the buyer intends to keep for some time; cost also has to be a consideration, though, as some of the premium hardcover collections are well on the other side of $50. What's your take -- what do you buy, and why?
