Digital BW, The Print

Hi Folks,

Sorry if this is has already been answered (I couldn't find the
answer) but is the R1800 yellow the same as the 7600 yellow?  I'm
asking because I'd like to reduce my costs somewhat by getting a 110ml
large format cartridge and sucking out the ink to use with the
refillable carts.

Thanks,
