X-OMAT 2 Dental Duplicating film
The following techniques are recommended for reproducing radiographs used to accompany patient records, as teaching aids, or in other applications where duplicate dental radiographs are needed. X-OMAT 2 Dental Duplicating film is intended for use in duplicators. Your dental X-ray products dealer can provide you with a complete list of duplicator manufacturers.
• Proper safelighting is required in order to produce a sharp duplicate image. Use a GBX-2 Safelight (ruby red) filter or its equivalent in your darkroom to prevent unnecessary fogging of the duplicating film. The safelight must contain a 15-watt frosted bulb and be placed four feet from the film surface.
• Duplicating film is a single emulsion film, meaning there is emulsion on only one side of the film. The non-emulsion or dark side of the film is a backing or pelloid that prevents light from passing back through the film, eliminating potential blur and creating a sharper image. The nonemulsion backing is a forest green color to differentiate it from the emulsion side, which is salmon pink.
• Unlike standard dental film, X-OMAT 2 Dental Duplicating film is a direct positive film. Therefore, when increased densities (darker films) are desired, exposure times must be reduced. Conversely, when decreased densities (lighter films) are desired, exposure times must be increased.
• As with all film, it is essential that proper processing be maintained with regular replenishment. When using severely exhausted chemistry, the X-OMAT 2 Dental Duplicating film will exhibit color streaks of pink and/or yellow:
