Digital BW, The Print

Hey everyone. I'm building a septone print workflow that prints with a  
form of fluid that I don't want exposed to either air or myself during  
setup. I also need to be able to flush the ink-lines for every print  
run of 2 40x50 inch prints. The fluid is really expensive so I want to  
use only enough to flush the lines (using air-bubble gaps to make a  
clean separation between flush fluid and printing fluid) and to print  
2 40x50 inch prints per run. Each photograph will use pretty much the  
same amount of each shade of ink. At first I thought about using  
virgin ink-bags and carts, but syringing this stuff out and shoving it  
into an epson cart messes with the cartridge alignment, ink delivery,  
and ends up leaking fluid. My second thought was to use Cone's bulk  
tanks, but this exposes the stuff to air too soon. It's fine if it  
gets exposed to air right before it runs through the print-head. I  
also need a completely clean cartridge every time I do a print-run and  
I can't really clean Cone's carts totally.

So my thought is to use IV bags and modular gravity-based IV system  
hooked to each ink-line. The IV's would be maybe 1/4th-1 inch above  
print-head to keep a good flow of fluid but not too much pressure.  
This way I can just hook in a flushing syringe and then a fluid IV  
bag. Everything is sealed and clean and leak-free and still gravity- 
fed just like the 9600 carts.

The problem is, everything I'm looking at needs a doctor's  
prescription to order. Even though there's no needles involved, just  
to get a freaking IV bag and IV line, you have to have a prescription.  
Does anyone know of a similar system that doesn't require a  
prescription? Is there any way to get a "research" prescription for  
something like this? Any doctors on the list? :-)

Your help would be most appreciated,
all the best,
