I havent used that particular emulsion, but I have used the other Arista films in 4x5 and 120 and was very pleased. I would think the copy film would do fine. You're going to have to contact print the intermediate positive back to a negative using another sheet of copy film.(posted 8729 days ago)I dont think the litho film will make a good long scale neg. I have used it as a camera film with a very dilute mix of HC 110, and it still would reach a point where it wanted to go solid black. It was very hard to control.
I would suggest another alternative as long as you are looking at the Freestyle catalog. Go to the printers and lithographers pages and look for a high speed dupe film, which will produce a negative in one step. It is meant for litho type materials, but I think you can coax it to hold a longer scale by diluting the developer. It is meant to be used in a strong Dektol-like developer for litho use, but it might respond to HC-110 and do the job. It should be about the speed of enlarging paper.
