Where can I find a reference source that expands on this? I had already come to the conclusion on my own that inkjet coatings could be a problem just because the manufacturers don't talk about them and are reluctant to tell you what's in them (one just flatly refused to provide an MSDS which is a Federal no-no), but I would like to know why these coatings are a potential problem.

Also...

On a semi-related topic: I have seen "Wilhelm years" mentioned here several times and could use a reference to an explanation. Apparently Wilhelm's tests are being "translated" into some other number that in some cases seems to imply that prints are virtually turning to dust as they issue from the printer <grin>. Anyway, it makes it difficult to compare the numbers for some of the B&W ink sets discussed here to Wilhelm's numbers for OEM inks. The implication that Wilhelm's results are overly optimistic leaves me with no point of reference.
