5. ILFORD July 2004 FACT SHEET PAN gL ISO 50 18 BLACK AND WHITE PROFESSIONAL FILM FOR HIGH PRINT QUALITY AND FLEXIBILITY IN USE ILFORD PAN F Plus is an extremely fine grain black and white film It has outstanding resolution sharpness and edge contrast These characteristics make it the natural choice where fine detail and lack of grain are more important than film speed Mural size enlargements from PAN F Plus negatives show an outstanding range of tone and detail when the film is carefully exposed and processed PAN F Plus is compatible with all major processing systems including those which give the standard short fixing and washing times PAN F Plus 35mm film is coated on 0 125mm 5 mil acetate base and is available in 36 exposure cassettes or in bulk lengths of 17 and 30 5 metres 55 and 100f PAN F Plus 35mm film is supplied in DX coded cassettes suitable for all 35mm cameras PAN F Plus rollfilm is coated on 0 110mm 4 mil clear acetate base with an anti halation backing which clears during development It is available in 120 lengths and is edge numbered 1 to 19 EXPOSURE RATING PAN F Plus has a speed rating of ISO 50 18 50ASA 18DIN El 50 18 to daylight The ISO speed rating was measured using ILFORD ID 1 1 developer at 20 C 68 F with intermittent agitation in a spiral tank Best results are obtained at El 50 18 but good image quality will also be obtained when PAN F Plus is exposed at El 25

10. mount of hardener cannot be used as the fix and wash times cannot be extended adequately In these circumstances we recommend starting with the minimum amount of hardener to have some effect This is around 3 6 mls of hardener per litre of working strength HYPAM used This increases the film hardness slightly but has a negligible effect on the fix and wash efficiency When fix and wash times are restricted the maximum amount of HYPAM HARDENER recommended is 10 20ml of hardener per litre of working strength HYPAM used This higher amount gives a definite increase to the hardness of the films processed and while fixing and washing efficiency are reduced the films will be adequately fixed and washed for most purposes When fix and wash times can be extended the maximum amount of HYPAM HARDENER needed to achieve fully hardened films is 1 part to 40 parts working strength HYPAM i e 24 ml per litre Drying To avoid drying marks use a clean squeegee or chamois cloth to wipe PAN F Plus film before hanging it to dry Dry PAN F Plus at 30 40 C 86 104 F in a drying cabinet or at room temperature in a clean dustfree area STORAGE Store PAN F Plus in a cool 10 20 C 50 68 F dry place in its original packaging Exposed film Once exposed process PAN F Plus as soon as practical Images on exposed but unprocessed film will not degrade for up to several months when stored as recommended Negatives Store processed negatives in a cool 10
