numberonenetwork #470 HP RA/Lith film?

Murray@uptowngallery · Mar 28, 2008

Hello:

I acquired some Kodak Ultratec UGF (open box, TBD what's really inside it) and
#1 Network (numberonenetwork.com - didn't find it on line)
#470 HP RA/Lith film.

I see Ultratec UGF described online as what I would assume to be 'ordinary' graphic arts lith film.

I would assume they are similar as the user had both at the same camera.

HP I guess means high performance...whatever that means.

RA I guess is Rapid Access type chemistry.

Are all or most lithography films about the same, or is there all kinds of variation?

I didn't find an expiration date on the Kodak, but the #1 Network stuff is unopened, stamped 11-06 (mfg?) "Use by 11-08".

Red safelite, so it's ortho (as I expected).

I have chems to make POTA and I think probably Delagi #8.

Any suggestions for in-camera ISO and developing starting point (for contone, not high contrast.)

Thank you

Murray

The Kodak Ultra-Tec was a Rapid Access lith hybrid from the late 80's till early 90's. I'm not sure of the results you will get without the dedicated chemistry because I think if memory serves me right the emulsion had some developer in it or something crazy like that. There hybrid wasn't as popular as some of the others for it had some short comings. I'm sure it's long past it's expiration date. My guess is it wasn't available after the mid 90's. As far as asa think low single digits at best. You wont get much continuous tone that much you can be sure of. Now as far as the numberonenetwork, that must be repackaged film from someone else. Agfa film was rusty colored usually or green, Polychrome was usully brown or blue, dupont was green, 3m was bluish but I never used Kodak camera film so your on your own there. But my guess is it's probably Agfa and any rapid access developer will develop it.

You can get continuos tone with Dektol, LC-1 or HC110 dil H for several mins. (DBI is warranted) Start with an EI of about 6, shoot some zone I exposures and aim for a density of .1 over Fb+F as a start. develop as needed to get the CI you want. It's not rocket science, and and no different than EI deterimination for any other film, just lower numbers.

Ortho film has some interesting properties, as well as a unique signature for landscape and detail type shots. Of course Murray already knows this, as he and I have had this conversation before and he already uses several lith films (or is it xray film??)

I also will add that Polychrome MCE film work quite well for contone work:

exposed at EI 6, processed in Dekto 1:6, by inspection.

I'll be honest, I COLLECT such films, fully intending to use them :O)
