Arista Ortho Litho 3.0 Overview
Ortho Litho 3.0 from Arista is a line and halftone camera film designed for pre-press applications. As a high-contrast film, it is characterized by a very steep gradation and gradation tone, along with a wide density range with high Dmax and low Dmin values for enhanced UV transmission. For halftone, high-contrast applications, rapid access processing in ACD chemistry, such as Majestic 650, is recommended; for continuous tone use, diluted B&W paper developers are recommended for lower contrast results.

For easy handling of the film, the emulsion incorporates a dedicated layer to prevent Newton rings, as well as separate anti-static and anti-stress layers to protect against dust, scratches, and other damage. Additionally, it can be handled and processed under a red safe light.

This item is one box of 50 sheets of 3.9 x 4.9" film; this film is cut slightly smaller than actual 4 x 5" in order to be used in conventional 4 x 5" film holders.
 
This film is typically 3 or maybe 6 ISO max, but the PFS-4 solution (done just before development) seems to really lift up shadows. Unfortunately had only minor effects on other brands of ortho litho film
 
This is awesome! I was wondering if you were still exploring painting on the back of ortho lith or displaying the film itself over a black background?
 
@Candlejack I could never find a paint that I liked for the purpose, and the front of it being so shiny makes it even harder than a super glossy print to display. The process definitely has potential but it got kinda boring to me and the ortho litho film is kind of a pain since its easy to unevenly develop and easy to scratch as well. Note that to get a positive image on a black background, you must effecrively make a film negative, not a positive!
