Figure 2: Grain Size Distribution Curve for PFG material.

The PFG Silver Halide materials are equivalent to the well-known technical photo-materials previously produced by Agfa and Kodak. All materials can optionally be supplied coated onto Polyester or Triacetate substrate films. The characteristic curve for the PGF is shown in Figs. 1. The grain size distribution is shown in Fig. 2.

PFG photographic plates are a practical replacement for Agfa (Millimask) and Kodak (HR-P, TE) plates. The plates are specifically designed for the manufacturing of high-precision photographic masks for microelectronics. High resolution, high durability and excellent adhesion of the emulsion layer to the glass substrate enable photographic features of less than 2.5 micrometers to be recorded.

All photo-plates are usually supplied in a cardboard package containing 6 units each. The largest plate size available as a standard size is 406x300 mm. The standard glass thickness is 2.5 mm. Antireflection plates coating on request. 
Guaranteed lifetime - 12 months. 

Processing and Handling Recommendations:
- Unseal and process in indirect non-actinic light with use of a dark-green light filter (transmission zone - 530 nm and less).
- Temperature of processing solutions - 20±2°C.
- Storage condition: Humidity 65% and 12-15deg. Celsius.
