It's complicated to compare the consumption of two series of cartridges.
If you have a weight scale you can do the following:
Weight a full cartridge and a totaly empty one. So you will have the weight
of the consumed ink of a whole cartridge. Even if the specific gravity of
different inks is different, it's a good assumption to thing the same
specific gravity (almost all inks are 1.01 to 1.10 ml/g, most inks in the
range of 1.02 to 1.07).
If you measure the above values for both oem and jt inks, please drop them
in this ng.
If you want to estimate the ink consumption follow this formula
