Yes it will, because the thickness of the paper and the folding makes it hard to unfold the signature completely. But we are talking about tenths of milimeters here (creed adjustment usually isn't bigger than that) so it won't be noticeable. You can try for yourself. Fold and stitch two sheets. Open the spread with pages 2 and 3, spray a thin layer of paint onto the sheets. Let dry. The open the spread with pages 7 and 6 and repeat. Remove the stitching and you will surely find a very thin white line in the middle of the sheets. /Peter
