Has anyone done some real permanence testing on todays inkjet printers, aftermarket inks and paper.? I do not mean the non verifiable data from Wilhelm or RIT, but accelerated data that has a 6 month or one year real world test daylight test (like Livic's discontinued work ) correlated to it. I believe that without this being done the reciprocity factors are just "swags" at best. My very controlled testing on dye based Epson inks, in the past, showed that the predictions from the experts were off by a factor of 3.
I want to purchase a new wide format printer and can not afford to make a mistake, given the current prices. Pointing me in the right direction will be appreciated.
You are completely in error in implying that the Whilhelm Research data is inaccurate and not "real world." Their data is found on actual scientific principles. They are the authority in print permanence. You should take the time to read the foot notes in their reported data and maybe even purchase their book on accelerated testing mehods and procedures.
Most dye based inks last only months. I have seen this myself with the Epson 1200. However, under certain conditions, pigmented inks can last for more than 200 years. That is a scientific fact.
A printer that has good print permanance would be the Epson 2400, 4800, 7800, 9800 or the new Cannon 9X00 printer. I personally own the 4800 and my works have been on display in galleries for over a year without any signs of color fading what so ever.
