>>23037241High DPI source file and setting the correct printer settings really help. You can easily tell them apart from real cards in person, aside from Kris not existing in the real TCG, that is. But having said that, they came out pretty solid and the way they're constructed they hardly even need the sleeves. They are printed as a mirror image and then the transparent foil is stuck to the clean foil card with the ink-side down, so it is protected by the transparent foil. Glueing it down is a bitch, though. Shit gets everywhere no matter how careful you are.
Note the Illus. entry is the artist's Pixiv ID. I dont speak moon so I didnt ask him, though.
