\The easiest consistency to track here is the green transect in the Voynich image. Notice how the stain never really crosses the boundary.*
\The other constant artifact is the red staining at the upper fold blue line/green line transect. While the corresponding stain on the MWS appears semi-circlular, this could easily result from the stain occurring while the MWS was folded along the top fold line.*
\The red marginal stainings*
\The staining from the VM also perfectly bleeds into the the broad shape of the MWS stain; notice both terminate at the Asian script, although slightly harder to see.*
\If you're having issues viewing the images at scale, I recommend viewing them directly via ImgBB as it should automatically scale to ~260% browser magnification and an additional image zoom without blur or additional scaling irregularities.*
