Digital BW, The Print

Hi!  I just set up a MIS inkset for a 1280.  I've had great sucess 
with the color set i have used on another 1280, and thought that 
the B&W set would be equally as nice, but so far i am getting 
bronzing in the blacks on Epson premium glossy.  I'll admit, i 
have just started doing the researching to find out how to 
properly set up printing, but the main reason i wanted to set up 
this machine was i thought i could get deep blacks on glossy 
paper like the 1280 color (i have a 2200 for matte stuff already).

I'm sure somewhere in the past there are posts here..i also read 
the info on MIS's website from Paul Roark but they say they are 
for Matte Papers, so i guess i'm asking for any advice or maybe 
just some points in the right direction.

the ink is FSN-HEX-E, which is correct i believe.

any advice is greatly appriciated!!!!
