Can I remove one of your refillable cartridges on an Epson 9900 printer and store the full or partially full cartricge for some time if, for instance, I wanted to switch between pigment and dye inks. Is there a shelf life for doing this? Is there any more issue in doing this with cartridges full of pigment inks than dye inks?
When I finally switched entirely to your inks from Epson’s ink, I noticed, I think, some loss in brilliance in some colors which I suspect has to do with the fact that Epson adds some dye ink to their pigment inks. Is there any reason I can’t mix some of your dye ink in with your pigment ink?
If this is possible, would you have a recommended dye ink/pigment ink proportion for doing this? Are there some pigment colors that are more lightfast that would fade less if some dye inks were added to those pigments.
