Peter, I'm a bit confused by this. If this issue is:

"The process of skewing pages to compensate for paper thickness as it is
folded.:

Then "Vertical allowance for plate bend" doesn't seem to relate to this.

As the paper is folded the center pages of the section creep forward. Shingling
as a binding term refers to  a method of compensating for that with different
width pieces of paper.  When folding a printed sheet, the foredge margin becomes
narrower in the center of the section if the book is trimmed on the foredge. The
width of the page there is less because of the creep. If you compensate for that
in the page design you would move the printed image closer to the gutter as the
pages approach the center of the section. It appears that the definition of
shingling in your context refers to that procedure.

The term bottling appears to refer to the vertical effect of page folding. As
you approach the center of the section the page creeps downward (if you are
folding at the head). That can be compensated by shifting the image upward as
you appraoch the center of the section. That will preserve the vertical
alignment of the images on the pages after trimming.

I don't understand where "plate bend" comes into this. Can someone elucidate?
