That isn't really what I meant. How are you scanning this? Are you scanning it as JPG directly?
Make sure you scan it as a TIFF or BMP. I don't recommend using JPG for greyscale pages at all, but if you must use JPG, it should only be done as the very final step. Whatever you do to edit your scans, it should be kept as a bmp, tiff, png, or psd until the very end.
It's not so much jpeg artifacts as much as it is a crusty scanner. It's not that bad but it's not good either. OP, invest in a better scanner if you plan on uploading long term. If not, it's still a good idea to have a decent scanner on hand.
Kutaka is one of my favorite new Touhou girls. Definitely a real cutie I'd love to cuddle and love. Also wouldn't mind to lewd cuddle and make some babies with. I would like to do it with her being willing, though. I really loved seeing Kutaka being knocked up! I hope this gets translated! Thanks SO much for this, yulu!
