I wouldn't worry about it at all. There are at least four active manufacturers of RA4 paper worldwide.
Pro labs have a very heavy investment in high-end printers that are dependent upon RA4. It's more
cost effective than inkjet. The most popular papers print fine either optically or digitally. New papers
have been recently introduced even by Kodak. Fuji has a heavy committment to this, and despite
the nonsensical post immediately above, the difference between current "digital" Crystal Archive and
the previous "analog" variety is only about 5cc's of green sensitivity due to the relative weakness of
green lasers. There's no difference in the principle of how exposure is accomplished, just in the marketing value of certain levels of contrast, which can always be tweaked with a little bit of masking if needed.
