Digital BW, The Print

I think you can simulate EIR as follows.

1) Take one IR picture and one full-colour picture of the same subject in 
exactly the same position and lens focal length. Obviously this is a tripod 
job and moving subjects aren't possible :-)

2) Convert the IR to greyscale if your camera doesn't already render it as 
perfectly grey.

3) Split the colour picture into red blue and green channels.

4) create a new picture with the IR as the red channel, the colour's green 
channel as the new picture's blue channel, and the colour's red channel as 
the new picture's green channel.

This simulates the response of EIR with a yellow filter on the lens.
