Usage Instructions
To prepare the develope
Dissolve 300 gms of Posidev Powder in 5 litres of water at room temperature. Store in a closed container.
For hand development
Place the plate on a clean bench. Use about 250 ml developer per m2 of plate. Spread the solution evenly over the plate with a developing pad or sponge. When the developer becomes exhausted, and darkens in colour remove it with a squeegee and apply a small amount of fresh developer to ensure a good clean plate. Use at 20°C. (Recommended temperature range between 18 - 24°C.) Keep the developer container closed after use.
For processor development
Fill the processor or tank to the correct level and use as indicated in the equipment manual.
Storage, Handling & Packaging
Storage & Handling
Store at moderate temperatures in a dry, well-ventilated area. Protect from direct sunlight. Keep the containers tightly closed. The use of gloves is strongly recommended while developing the plate manually.

Avoid skin and eye contact. A wider temperature range can be tolerated but higher temperatures may attack the image area and lower temperatures may require longer development time.
