Digital BW, The Print

Thank you Paul!

I just bought a second Epson 7600 to use for B&W printing. It only had 
1000ML of ink through it, almost new.

Here are some quick calculations I did for mixing up 1 liter of each of 
the Carbon 6 inks:

					
INK	Eboni	Base	PrevInk    NextInk    Remaining 
K	1000			                1000 
C	650	1300		   (950)	1000 
M		950	950	   (900)	1000 
LC		900	900	   (750)	1050 
LM		750	750	   (500)	1000 
Y		500	500	        	1000 
				

"Eboni", "Base", and "PrevInk" refers to the ML of each of those 
components used at that step.  "NextInk" is how much of the ink mixture 
from the current step is used by the next step/next ink.

Sorry for the formatting, text-only posting makes it messy.  ;>)

	
Here are the cost calculations to make the above inks, not including 
any flushing fuids:

Item	         ML	Cost	
Glycerine	1232	$60 	1 gallon
Distilled Water	2728	$5 	1 gallon
Photo Flo	426.8	$7 	1 pint
Eboni           1650	$200 	2 liters
		
Total Cost		$272 	
Total Ink, Liters          6	
Cost per Liter		 $45 	


Note that some Eboni and quite a bit of glycerine is left over after 
making the first 1 liter per "color" batch. 

Making a total of 3 liters of each "color" of ink - or a total of 18 
liters of ink -  uses most of the raw materials and brings the average 
cost down to $33 per liter. Total cost is just under $600.

Best,
Michael
