"Fuji Crystal Archive" is the brand name of the paper used. You can use it in
your darkroom. Rated 65 Wilhelms.
The Lightjet IS a digital printer, albeit one that uses photochemistry in the
final step.
I propose the following:
Optical: an analog process by which light produces images.
Digital: a process by which light is quantized into digital files at ANY point
in the process.
Photochemical: a process by which light causes a latent image that is processed
using chemistry. The exposure may come from light that is produced digitally.
Ink Jet: a process by which drops of ink are applied to a substrate.
Electrophotographic: a process by which light causes a colorant to be attracted
to a substrate via static charge.
Giclée: an ink jet process characterized by large size, long lifetime (>100
Wilhelms), and six or more distinct ink colors. (This from TruGiclée(TM) Inc.,
an art printing standards body.)
So the Scitek Lightjet (or Durst Lambda) produces "digital photochemical
prints," as does the smaller machines (Fuji Pictography) that are common in
neighborhood photo labs.
There's no sense arguing over which is better, if we can't even agree what the
different techniques are!
BTW: there is no better book for such things (IMHO) than Harald Johnson's
"Mastering Digital Printing."
