Digital BW, The Print

Hello,

As my first foray into "serious" B&W printing I've recently set up and 
dedicated an Epson C86 with the MIS EZ B&W Warm inkset. So far I'm 
thrilled with the results both from digital capture and scanned B&W 
negatives (thank you Paul Roark & MIS Associates!).

Next I'd like to make some neutral prints. Am I inviting trouble by 
doing this on the same printer by swapping cartridges? I know I'll 
need to run a bit of ink through the head after swapping a cart to 
prep it for the swapped-in ink cart, but other than that is it wise to 
let partially filled cartridges sit on the shelf (probably upright in 
a sealed plastic bag)? I'm using refillable carts and have a chip 
resetter, in case that's a consideration.

Thanks,
Mitch
