S43 is a steel backed, nylon-photopolymer coated, alcohol developed plate material. The total thickness of the plate is .43mm. This plate material is superior to the water wash plate material in that the plate will last longer and will hold finer detail. The print impression capability of the S43 is rated at 20-30,000 impressions.

*The photopolymer color is a medium-dark green. 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 developer and a plush brush for the friction removal of the unexposed / dissolved material.
*immerse the exposed plate in the alcohol developer and rub with brush to remove unexposed material.
*The developer is a special alcohol-water mixture made for alcohol washable plates.

-Art Film* Exposure time**: 90-120 seconds (Using the All American EB-320 plate exposure unit)
-Screen Tint time**: 90 seconds (less time for more depth/more time for less depth in the etch)
-Washout time: (using Alcohol Plate Developer) 3-4 minutes @ 35 degrees Centigrade/ 95 degrees Fahrenheit.
-Drying time: minimum of 20 minutes @ 80 Centigrade / 175 Fahrenheit
-Post Exposure time: minimum of 20 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.
