Posidev Powder is a premium powder developer concentrate for most positive presensitised plates.
Features & Benefits
Powder form makes it easier to store than liquids.
Readily soluble in water.
Contains sequestering agents so that normal supply of water can be used to dissolve the powder.
Diluted developer gives good results by hand, tank or automatic plate processor with excellent dot reproduction and fidelity.
Excellent consumption rates – up to 4m2 / litre by hand development and 10m2 / litre by plate processors.
Compatible with most aqueous developed positive presensitised plates.
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

:
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.
Shelf-life
:
12 months from the date of manufacture.
Packing
:
300 gms.
Precautions
:
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.
