Even if they don't try to improve it, every batch will be
significantly different -- that's just the nature of making
complicated recipes in a batch process (as opposed to a continuous
line). With paper products, the production of which uses a number of
toxic chemicals that regulators are increasingly trying to control,
it is often not possible to make the next batch exactly the same way
as the last.
Anyone who wants to minimize batch-to-batch variability should start
printing on plastic sheets, Tyvek, aluminum, ceramic, or similar substrates.
Alternatively, if you find a paper you really like, buy a lot of
it. Not hundreds of sheets, tens of thousands of sheets (or whatever
will be a lifetime supply). And store it properly.
