NovaFlash Sensitiser A&B
(Plateroom Chemicals - Product Code : 310201X)
Description
A composite mixture of photosensitive coating for wipe-on negative platemaking on finely grained/anodized aluminium plate.
Characteristics
- Two part chemistry of Sensitiser A (powder) and Sensitiser B (liquid).
- Sensitive to heat and light. The colour of coating turns from golden yellow when freshly mixed, to dark brown when exhausted.
- To be applied on thoroughly cleaned and dried plate surface.
- Exposure to UV light hardens the coating.
- Suitable for manual and roller coater application.
Instructions
Completely dissolve Sensitiser-A powder in Sensitiser-B liquid. Coating may be applied manually or in a roller coater. Bubbles should be avoided/allowed to settle down while mixing.
For Manual Application
Use a freshly washed sponge after removing the water completely. Pour a small quantity of mixed NovaFlash Sensitiser on one edge of the sponge. Place the plate on a clean flat bench and apply the coating with by wiping the sponge in parallel strokes with equal pressure, along the length of the plate. For even coating the wiping action may be repeated across plate after squeezing off excess coating from the sponge. Care should be taken to avoid uncoated patches and streaks. Fan-dry the plate.
For Roller Coater Application
The mixed Sensitiser can be used directly in the coating tray.
Caution
Yellow/orange safe light is recommended in the areas where plates are coated and dried. Dust or dirt on the plate and use of contaminated sponges will cause plate-processing problems. The plate surface should be dried thoroughly before coating in humid atmospheric conditions. Moisture contamination could result in poor adherence of coating and premature image wear.
