f46v/47r ink transfers or erased drawing?

[Wladimir D]

A few years ago, I carefully examined these prints by overlaying (by layers) a mirror image of the notch of three prints of page 47r on the original 46v. The coordinates of the relative position of the three prints coincided with the original (with a slight angular correction relative to the vertical).
Another point about these pages.
If you combine these pages, guided by the contamination at the touch of a page (the blue rectangle - is a modern binding), all the prints are 47r shifted upwards relative to the original by about 4 mm.
From this we can conclude that the drawings of the contours of the colors were done before stitching Q6 (the bifolios were shifted vertically when nesting into each other), or drawn, with the possible pre-existing linking.
