How do old comics get reprinted?
Hi guys, I recently purchased "Superman - The Golden Age Omnibus" and "The Avengers Omnibus" and I was wondering: how do these old comics get reprinted? Are old issues scanned and then digitally remastered, or does Marvel and DC still have the exact submissions that they gave to the printers, going all the way back to Action Comics #1 (and possibly before)?
Don't know why I need to ask this, maybe because I've been involved in printing before, but it's a question that's eating at my brain. I also noticed some definite digital re-colouring in the Superman Omnibus, which I'd prefer wasn't there. How often is this done?
One collection I've always been dying to get is Marvelman, but since it's been reprinted, I've decided that I hate the new colouring and am wondering if Marvel will reprint these issues in their original colouring.
Thanks if any of you guys can help with these questions. Love these collections, by the way. I prefer them nowadays over single issues.
[edit: Woops! I meant Miracleman, not Marvelman]
