ILFORD ORTHO Plus black and white copy film is designed for many applications. It is particularly recommended for continuous tone copy work, with no sacrifice in quality when the original includes line work. The blue and green sensitivity enables the film to be handled in red safelight and allows processing by inspection. This versatile film allows you to fine-tune the contrast by the choice of developer, the exposure given and the development time. It is possible to achieve an accurate reproduction of most black and white originals, or to maintain a clean background in copies of combined line and continuous tone originals.
