Here is a short passage from the web page
http://www.thepapermillstore.com/pages.php?pageid=190
You most likely won¹t see or notice the expansion and contraction of unbound
paper, but you can be sure it is happening. Paper fibers expand and contract
as much as 400% more across the grain direction of the paper fiber than with
the grain direction.
Go to this page for an explanation of what ?across the grain direction¹
means, and other interesting info. This fellow seems to know his business,
but there are many other sites that address this topic. Assuming even
application of the emulsion, it seems to me that this principle should also
apply to photo paper.
