Digital BW, The Print

Hi,

I know this question isn't really appropriate for our group, but I 
have one MIS Archival Color cartridge for my Epson 1280 and was 
wondering if it's okay to use it with an MIS FSN Black cartidge 
(versus their Archival Black ink)?

I'm imbetween B&W projects and thought I might check out the archival 
colors during the next week.  (My MIS VM ink cartidge is about to run 
out, but I have plenty of ink left in the Black cartridge.)

Thanks.

Bob
