Judging from info available on the web - from both Epson sites and others - Epson (as probably do the other major printer manufacturers - especially of pro models/equipment) obviously spends a lot of time and money considering putting ink (or other solutions) on media.
Here is a blurb from one Epson related article - it should be clear that researching performance on the atomic molecular level costs $ / time expertise that you probably won't find at 3rd party vendors.
from the article:
"The researchers actually found it relatively easy to improve on the ink's light fastness (its ability to maintain its chemical composition and color under lighted conditions). Similarly, it was not difficult to improve on the ink's gas fastness (its durability when exposed to naturally occurring gases like ozone, which cause ink to deteriorate over time).
"The real challenge came in maintaining or improving the ink's quality when modifying it to improve its overall durability," says Kitamura. "This was very difficult." Success was only achieved after the researchers significantly altered the ink's chemical structure at the atomic level, a process that resulted in the creation of new chemical compositions.
Kitamura explains that light and gases cause ink to deteriorate by leaching away electrons that form the bonds between the atoms of the ink's molecular structure. Over time, this leads to a breakdown of the chemical structure, resulting in fading colors.
To counter this, the researchers created new chemical formations by adding additional atoms to the dye's basic molecular structure, and then engineered the molecules into tight clusters. This not only strengthened the ink's atomic bonding, better protecting it from the effects of light and gases, but also improved the quality of the ink."
Looking at Epsom's technical and business plan - they're banking a lot on the peizo head technology for not only 'paper' printers, but for printing out LCD patterns, circuit patterns, et.al. That involves R&D science and engineering - investment - especially when tolerances are measured in microns, and the 'printer' is the size of a small warehouse. Paying a few cents more per print for Epson ink and the expertise that goes with it just re-enforces my faith in their product every time I produce a print. I'm sure the same is true with HP Canon et.al. -
