Pre-conditioning |
Although all films are pre-conditioned it is highly recommended to
stablise single sheets to ambient conditions for a few hours prior to
exposure (Avoid exposure to UV-light and any chemical vapours such as
ammonia). |
Exposure |
Ensure contact of the photo master to DENSOTRANS® is emulsion to emulsion. Place and
expose in a vacuum-frame with strong UV-light (Metal halide lamp) approximately for 40
seconds with 5kw light source with a distance of 80 cm. A Stouffer step-wedge can be
used determine the correct exposure time. |
Development |
DENSOTRANS® is developed in a ho, dry diazo machine with concentrated ammonia (25% resp. 24 Baume).
The film cannot be over developed, however we recommend two passes for complete and safe
development.
To ensure utmost image accuracy allow 1 hour after processing, for the
film to re-adjust to your working conditions. |
Dimensional Stability |
Effects of temperature change: 1.7X10-5mm/m/oC. (PET base)
Effects of humidity change: 1.1X10-5mm/m/%rh. (PET base) |
Storage |
Unexposed film can be stored in a conditioned environment and kept in
its original packaging for approximately 12 months. High temperature and
humidity may cause premature ageing. |
