FOMAPAN R

BLACK-AND-WHITE REVERSAL FILM

In General

FOMAPAN R is a panchromatic sensitized black-and-white reversal film intended

for taking black-and-white transparencies and/or making movies. From the shape of

the characteristic curve it is evident that the film is characterized by very good

differentiation of fine gray shades both in areas of highlights and shadows. In the

areas of normal exposures, the linear part of the characteristic curve shows the

gradation of 1,1. The spectral sensitisation of FOMAPAN R is designed for to true

transfer colour tones into the gray scale when exposed in daylight, and

simultaneously to make full use of the film speed when exposed in artificial light.

Due to a very efficient antihalo layer, situated between the base and emulsion

layers, the film features very good resolving power and high contour sharpness.The

antihalo layer will decolorize during processing.

Speed

The film has a nominal speed rating of ISO 100/21 o when processed in R-100

Process. Other processes can cause deviations from the nominal film speed. It is,

therefore, recommended that the real film speed be checked by trial tests in such

cases.

Processing in R-100 Process

Packaging

FOMAPAN R is available as:

• one-edge perforated 16 mm film

• 2 x 8 mm film (standard)

• 2x Super 8 mm film (DS 8)

• both-edge perforated 35 mm film in 135-36 cartridge for 36 slides of 24x36 mm or

as bulk length goods in customary lengts.

Safelighting

FOMAPAN R should be processed in total darkness or under infrared light until

including the processing step 6 (washing before the second exposure). If, however,

an illumination for reference or short-term orientation before this processing step is

necessary, it is possible to use a safelight fitted with Agfa 108 filter, 15 Watt lamp,

indirect light, at a distance of at least 150 cm from the workplace.

Storage

Unexposed films should be stored in the original packaging in a dry and cool place

(at temperatures ranging from 5 to 21 o C and relative humidities ranging from 40 to

50 %), out of reach of harmful vapours, gases and ionizing radiation. Films stored in

a refrigerator and a freezer should be adjusted to room temperature before using for

about 2 and 6 hours respectively.

Exposed films shoud be processes as soon as possible. In cases this condition can-

not be kept, the films should be stored at lower temperatures (4 bis 18 o C) and

relative humidities less than 60 %, out of reach of harmul vapours, gases and

ionizing radiation.

Processed films should usually be stored at temperatures up to 21 o C and relative

humidities ranging 40 bis 60 %. For a long-term storage (e.g. in archives), special

regulations of coresponding institutions should be adhered to.

Base

FOMAPAN R is usually produced on a cellulose triacetate safety film base

demands concerning mechanical resistance and dimensional stability are made on

the film.

FOR PROCESSING OF FOMAPAN R BLACK-AND-WHITE REVERSAL FILMS

In general

The Process R-100 is an analogy to classic processes for black-and white reversal materials. It is intended both for the manual processing in dish/tank and for the

machine processing in developing machines. Both in the first and the second development the commonly available developer Fomadon LQR is used and recommended

for optimum results.

If the developing machine used does not allow to provide the second exposure, a reversal bath formulated below should be applied (similar to E-6 Process).

This product is manufactured and marketed in conformity with a quality system according to the

international standard ISO 9001.
