    I see a lot of lightjet prints being made on this paper. Does anyone know much about this paper? What "type" of paper is it and can you hand print color negative to it? Has anyone here ever hand printed onto crystal archive? Just curious, thanks

    I use it all the time in the darkroom. It's my paper of choice. Very sharp and excellent colors, not to mention the great tonal qualities.

    It's just a regular, RA4 c-print material.

    Last time I thought of color prints and which paper they were on and what it is called, it was C print was from a negative and R print was a reversal.

    I may be wrong.

    It is also supposed to have a pretty good life-span. I want to say 60 years, but I could be wrong there. Nice stuff though as color papers go.

    C--neg/ R--reversal.

    yeah, CA is rated in some tests to do very well--in the 40-65 yr range under the target conditions....Wilhelm's book covers some Fuji papers--SFA3--from the previous generation, and these outperformed just about all other c-papers, they had one at one time on a polyester base that was supposedly very stable as well.

    Sheesh - I've been using RA-4 paper all over the place to print Color Negative images. You mean - the stuff was intended for reversal film??

    Sarcastic key [off]. Seriously .. the "c" was derived from (C)ibachrome - which is a direct positive paper. The "R" as in "RA-4" paper is from -- I haven't a clue. Could it have something to do with "resin"??

    I know it replaced the "old" EP-2 process ... I would imagine that was from something like "Eastman Process, edition #2..".

    DKT to Ed translation:

    C-print="chromogenic print"--a print from a color negative. RA-4 prints are C-prints. LightJets on Fuji Crystal Archive are "Digital C-prints"--digital output on the same paper used to print from color negs.

    R-print="reversal print", which would include Fuji, Agfa, and Kodak reversal print materials as well as Cibachrome, though Cibachrome is a very different kind of process.

    RA-4 is just Kodak's designation for a chemical process for processing C-print paper, not unlike designations such as "E-6" or "K-14" or "C-41" for various film processes.
