   This material is of a high linescreen usually 135 LPI to 200 LPI. 
The photographic emulsion is applied to backside of the screen at the time
of manufacturing. At this point the screen is considered transparency material.

   The entire screen is exposed by multiple negatives, processed like a
regular sheet of photographic paper and if a print is desired a reflective
coating is placed on the back of the material.

   As far as an individual is concerned, purchasing this material is near
impossible unless you're interested in a lifetime supply.
