"Digitally optimized" just means a tad more sensitivity to green, since this is the weakest beam with laser printers. These papers work perfectly for enlargment too. "Type C" was just generic jargon. The
specific "Super C" Fuji papers are still for sale, but at not their current product. The latest is Type II C.
Here's how it differs: slightly thinner paper, and available in sheet only up to 20x24 (above that, rolls),
slightly less contrast, but whiter base, so some hues do come out richer. I like it better than Super C,
but it does need to be handled a little more carefully. In terms of color balance, they're almost identical. What I don't know at the moment is how exactly Type II Supergloss polyester-based media
(vs RC paper) differs from the previous version. And I'm just about the find out. I just cut some test
sheets from a master roll last weekend. I expect it to be stunning.
