All scans x1600, grayscale png for b&w pages, jpg for color. Black is black, white is white.
After 3rd volume some pages that were color in original were made into two color tones or b&w by US publisher for whatever reason, and with a few exceptions, I've made them all grayscale and tried to make them look better as b&w. Same with pages that were b&w in original, but were in RGB and looked like in blue colors in digital.
Also, some volumes, for whatever reason, appeared to have black been painted with marker or something and slovenly overlapping visible screentones. While it could be some artistic intention, Japanese originals didn't appear to have them, so I've tried to make them as lass noticeable as possible without darkening scans too much while at the same time somewhat keeping those things for aesthetics.
