When the gutter has to carry the spell
A double-page in a Doctor Strange–inspired artbook is a single thought. The gutter is the hinge of that thought. If you paint two symmetrical mandalas and hope the binder will make them meet, the spell splits. The reader feels a white wound down the middle of the circle, then blames the paper.
On the Bagendon table we draw the fold first, as a pencil line on the dummy, before any cloak or street. The line is not decoration. Captions may not sit on it. A relic may cross it if the object is the spell. A face should not be cut unless the chapter is about a divided earth and you want that cruelty.
When we ink a mandala spread, we leave a slightly darker ring on the verso where the circle continues, so the eye completes the shape even if the bind is tight. Collectors who only see the NFT crop of the title spread miss this, because the token is usually the recto. That is why the colophon still mentions the fold.
If you are briefing a splash, say whether the gutter is a seam, a tear, or a door. Those three words change the inks more than a mood board does.
