Digital BW, The Print

Hello paul,

I have received MIS UT FS inks for use with my custom workflow on a 
1280.  But I forgot to order the magenta ink I need for modifying ink 
tone.

Q:  I have some MIS GP (designed for 1280 printer) magenta ink.  Will 
this ink be compatible when added to the FS dark ink?  Or should I 
just buy a 2200 mageta cartridge and decant ink from it?

Thank you and regards.
