I'm a devout believer in fast editing... my scanner does half the work. I do a 'preview scan' when I start a new comic, which the scanner then uses to automatically adjust brightness & contrast. Then there's a setting to automatically square-up the images. So I just have to do a quick trim, flip(if necessary) & save 'em.
This comic was a pain mainly because of where the staples are; many scans end up with no border at the spine, or even with a sliver of art cut off. I've removed staples before from low-cost issues (coverless &/or incomplete), but I couldn't from this one.
