Watching red color really hurt my eye. >_<
They usually don't fit correctly at all. Light isn't perfect, so you shouldn't ever get a perfect 100% exact replica, otherwise they would fit correctly. (unless your scanner is capable of producing a constant array of light ^^) In retrospec, the image is usually off by 3 - 7 pixels when scanned at 600dpi.
They're usually not off nearly that much; you're probably just not aligning them right. If they don't line up, they're usually not rotated correctly. Sometimes finding the correct alignment can be difficult, when there's nothing handy to align against, but if it's aligned, it should be within a couple pixels.

Make sure you do any color adjustments exactly the same; if you use anything like auto-contrast, it needs to be done after they're joined and not before. You shouldn't have any problems with color differences if you do it right.

Once in a while you'll hit pages that were printed differently--at a slightly different size or color, and you'll have to work around it. That's not too common, though.
Thanks for the explanations. But please take a look at the child posts which include the original images. Even there's nothing wrong with scanning, the two pages still can't fit exactly, coz some pixels are replaced by a blank gap for binding. I'm just wondering how he made up the missing pixels coz it seems as if the two pages were not seperated at all!
You can see some clone tool work on post #21917

I wonder if the other 'fixed' ones are new scans?
hehe, fixing images scanned by who hasn't photoshop skill takes you wastfull time :p

don't know his way, but my way is conbination of clone/patch on PS & blush on SAI.

Most likely it's not completely straight, cause I know I can't align my paper straight when I scan them :)

I'd say most of mine are around the 3º - 7º off :)

Alt + 167 = º symbol
You'll almost always need to adjust the rotation to get them to line up.

See basic_crease_and_gap_fixing for some introductory stuff...
stapled book has 0.1°~0.5° slope on the print, but glued book has 0.05° or less.
for almost scans, I just rotate 0.05°~0.25° on Gimp (coz CS's rotate/crop tool arn't work feely) if it needed.
You can perhapse read this before you comment once again.
