A similar type of film to that sold by Mackie X-ray is a black and white copy film, which is designed for many applications. Although it is particularly recommended for continuous tone copy work, with no sacrifice in quality when the original includes line work, it is similar to Mackie's orthochromatic film. 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.
The characteristic curve of this copy film has been optimised to ensure the tonal range of the original image is maintained. This is different to conventional films, which can give a dull, flat result when used for copying. The qualities of a high resolution film with precise contrast control is just what is needed for photomicroscopy. This copy film is highly recommended for this application.
These copy negatives are coated on 0·180mm/7-mil polyester base, well known for its high dimensional stability and strength. The negatives are protected by an efficient anti-halation backing which clears during development. If processed and stored properly, these copy negatives have excellent archival storage properties.
PROCESSING
This copy film can be processed in all types of processing equipment including
rotary processors, dishes/trays, deep tanks and automatic processors. Standard
capacity figures and replenishment rates can be maintained. Safelight recommendations.
Use an dark red safelight illuminated by a 15 watt bulb. As a precaution against
fogging and hence reduced image contrast, a minimum distance of 1·2 m/4ft
between the safelight and the working area is recommended. For best results,
keep safelight exposure to a minimum.
Agitation
Intermittent agitation is recommended for use in deep tanks. Continuous agitation
is recommended in dishes/trays by rocking the dish/tray. Otherwise, follow the
recommendations given by the processing equipment manufacturer. Stop, fix, wash
and rinse. For best results it is recommended that all process solutions are
kept at the same temperature or at least within 5ºC (9ºF) of the developer temperature.
Exposed negatives
As with any negatives, once exposed, process these copy negatives as soon as
possible. Images on exposed but unprocessed negatives will not degrade during
normal working periods, that is, up to one month when stored as recommended.
