Peter,

I think that in to a large extent the type of info you are looking for is
being closely guarded by the manufacturers which makes it tough to discuss
the differences an effects. It would be like asking Ilford what their
gelatin formula is for their papers. They just aren't going to publish that
info.

I would love to know more about ink receptor coatings, sizings and
brighteners but I don't think we will get it.
