+ Yes, the polyester is "Kleerbase" brand. It's used in the printing trade,
and as the name suggests, is clear and transmits light.

+ B&W original
1. Contact print the negative onto another sheet of 4x5, to create an
interpositive.
2. Enlarge onto lith film, to the size desired.
Color transparency original
1. Create a highlight mask, register it with the chrome, and then make a
contrast mask.
2. Enlarge the masked chrome onto lith film, to the size desired.
Note: with a very low-contrast chrome, it's sometimes possible to skip step
1.

+ Yes, but, the pin-registration method does offer many advantages.
