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 100 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.
