Digital BW, The Print

The only transparency material out there (that I know 
of) that will hold enough ink to get the density's 
needed is Pictorico OHP.

The problems are:

1. Zero dot gain, any inconsistancy in the printing 
sticks out like a sore thumb, the dither patterns (and 
the peizo pattern) are painfully apparent.

2. The dark end of the negative has an extreme image % 
vs print density curve that needs to be straightened. 
this is true with both the epson driver and the peizo 
driver. Applying a correction in curves with this 
results in noticeable posterization. If this could be 
handled in 16 bits in a rip, that may take care of it.

I'm glad to hear others are interested in pursueing this.
