It is not so much expense of the printer that's the issue (although
obviously a really bad ink could mess up a printer head and a more
expensive printer costs more to repair or replace...)
But that's not the real issue, in my opinion. The real issue is what
these compatible pigment inks are like.
It is relatively easy in terms of ink formulation, to make a dye ink.
Dye inks are solutions, like mixing sugar and water. The dyes dissolve
into the liquid base, so unless the company is using really incorrect
materials, or isn't using basic technical hygiene, you could expect the
ink to somewhat function, and again, usually they are fairly easy to
clean out even if a mistake is made.
Pigment is is another level of sophistication in the formulation and
manufacturing process, and even in how the cartridges are designed.
Pigmented inks require not only carefully selected colorant, but the
grinding process, and the resins used are critical to how bright it will
be, how well it will adhere to papers, how well the color will cover the
paper surface (density), if the colors will produce metamerism (were
they change relative to one another in different lighting sources how
translucent they will be (the ink dots intersect one another).
We really don't know what "compatible" means in this case. The inks
could be dyes but they "work" in a R800, or it could mean that they will
mix with the pigment inks left in your often cartridges without clotting.
Or, maybe they are really pigment inks, but how will the heads respond
to them? With they have similar color gamut, will they have similar
adhesion on the paper, will they be as scratch resistant (remembering
pigment inks tend to sit more on the surface of the paper than dye ink)
will they dry evenly and provide a similar gloss or matte finish? Will
you find similar papers that will work with them, will you need new
driver profiles for the ink colors? Will the inks be as archival, will
they fade evenly, which is important in keeping color balance, even if
fading does occur, etc, etc.
It is not that I'm necessarily crazy about the amount of money Epson
brings in on these inks, but the question may be, why did you spend so
much on an inkjet printer, if you are going to replace the inks with an
unknown quantity?
Pigment ink formulation is much more complex than dye inks, so I have
more difficulty saying "any old ink will do" with pigment inks.
