The stock isn't going to change the spectral characteristics
of the colorant+stock to any great degree, and even if
you were using different colorant (unlikely on a dongleized
ink cartridge), its isn't going to matter - you're measuring
separate colorant wedges, even a wideband reflectance sensor
will work (albeit with a poorer signal to noise ratio
that a filtered one).
