WS-43 is a steel backed, photopolymer nylon coated, water washed pad print plate. The total thickness of the plate is .43mm. The WS-43 is easy to image, gives very good detail and when properly exposed and dried, doctors very clean. The WS-43 can be expected to yield upwards of 15,000 -20,000 impressions.

*The photopolymer color is a medium-orange. Sold in packages of 5 (5 plates per pack).
*The maximum emission of the UV light source should be between 360-380 nm.
*The most suitable type of washout is a flat container to hold the water and a plush brush for the friction removal of the unexposed / dissolved material.
*immerse the exposed plate in the water and rub with brush to remove unexposed material.
*The water can be tap water.

-Art* Exposure time**: 90-120 seconds (Using the All American EB-320 plate exposure unit)
-Screen Tint Exposure time**: 90-120 seconds (less time for more depth/more time for less depth in the etch)
-Washout time: (using warm water) 2-3 minutes @ 25-30 degrees Centigrade/ 75-85 degrees Fahrenheit.
-Drying time: minimum of 20 minutes @ 80 Centigrade / 175 Fahrenheit
-Post Exposure time: minimum of 20-30 minutes

*A densely imaged black on the art film is critical to getting a proper etch depth. If the image is not dense enough to block the UV light, the resulting etch will be too shallow.
**Exposure times are suggested times and will vary according to the relative strength of a particular light source.
