Re: Scanning manga
Of course you're allowed to post that question. And here is one of the best places to ask that as well.
What I can tell is that there are no specifications to scanning manga. We're happy about anything.
What you could pay some attention is the quality of your scan. The higher it is the better. Of course some 10Mpix scans wouldn't be handy to others, so mind the size as well, but on the other hand, high resolution scan will be extremely convenient to Manga Editors as they can make as high quality Edited Mangas as they like.
One minor thing could be the looks of page as well. Everybody expects the HQ scans not to have the shadowing on the pages (you know, the one coming from incompletely bent spread). So if you intend to make HQ, then avoid such things.
To sum up I could say that three things are important: Quality, Size, Looks
