Digital BW, The Print

Hello,
Several years ago I started with quadtones in my Epson 1160, using 
the VM colorset, but after a time, didn't really like anything other 
than a warmtone set. Starting with a new cartridge in my CIS, I took 
the VM toned ink in the Yellow position out of the inkset, and put 
the Original MIS Quadtone 25% in its place. This gave me a warm 
inkset that I've been using successfully for about 5 years & with 
several new bottles of the same ink purchased since. 

Recently I purchased a new set of these same inks from MIS, at the 
same time that I installed a new cartridge set. I still had about an 
inch of ink in the previous bottles, but elected to just use the 
newer full bottles in the cleaned CIS unit, with the new cartridge. 
On printing tho, I noticed strange greenish casts in my prints. I did 
a swab test on the Magenta position ink, and noticed a big difference 
in comparison to the previous bottle labled as the same ink. 

I contacted MIS Support and sent a swab comparison of the VM-Quad-4-
M. After some time they've come back and said : "The tests have all 
come back correct on our side. The best option would be to send the 
bottle back to us and we can test it further, and if need be replace 
the bottle.Please contact us if we may assist you any further."

So I did a full swab test of the two sets - previous and new - and 
come up with astounding results. I've forwarded these tests to MIS 
also, before taking any more steps.

Any ideas from the group?  See the swab test at
