...If it has good longevity and same IQ as the epsons? If I can print straight from my mac, with the same quality as IP it would be great fro me...
The ConeColor ink has never been through an independent light fade test, AFAIK, so there's no information on lightfastness at present except for anecdotal stories/opinions you will hear in various forums contributed by third party ink users. The digital printing era is still young, so any anecdotal information that states no observed fading may be promising but doesn't really tell us yet whether the ink meets or exceeds OEM ink on durability merits because the real world time frame hasn't been long enough.
That said, I recently received a couple of samples printed with ConeColor ink on two different RC Glossy/luster papers. Both samples have just entered the Aardenburg standard light fade testing protocol, so we will soon have some comparative laboratory results on light fastness, but with only two media in test so far, the sample size is probably too small to be able to definitively answer the general question on longevity versus the OEM inks unless the results are way off the normal mark. We shall see soon enough.
As for color gamut, this can be easily determined and quantified. I have not personally used the ConeColor inks, but I've closely examined Epson K3VM versus ConeColor printed samples on Epson Premium Glossy paper, both ink sets printed on the same batch of paper. They compare very closely with each other with respect to colorfulness, Dmax, degree of "bronzing", and differential gloss, so IMHO, the initial image quality of the ConeColor ink set is likely to satisfy anyone, even die-hard advocates of OEM inks. As for printer reliability with ConeColor ink, again I read many good reports on various forums from endusers and this is reassuring, but again this information doesn't stem from head-to-head comparative testing to truly answer that question. Bottom line: using third party ink always involves various risks compared to OEM, but for many people looking to save some money or looking to go down a road less traveled for artistic reasons, they have concluded it is worth the risk.
