    That's interesting, the fading effect depends on the ink in use, the paper and the environment; you mention that
    ' but later, they caught up to the prints that had no GO applied ' - how long was this period - weeks or months - for your test ?
    Yes, they perform much better - significantly, but I don't like their look in some cases but that's a different story...

    Please let me update on the fading results after another 4 weeks, there was quite some sun, and it was pretty dry,
    all factors which may influence the results this or that way, and I'm running this test only on one type of paper, tests
    some years ago had shown that the paper, the coating as well has an impact onto the fading performance of a particular ink. Changes in colors for the patches w/o GO are now becoming visible in direct comparison with the reference patches kept in the dark


    Fading Test Epson 106 ink - w/o and with GO overprint
    Total Lightness increase of CMYK patches (Range from 0 - 255)
    (measured with a scanner, deltas via the histogram vs.
    a copy kept in the dark)
    L800 Printer, Epson 106 inkset, Ultra Glossy driver setting, Sihl glossy paper

    after week 1__________1_________________0

    after week 4__________4_________________3

    after week 7__________8_________________5

    15 weeks are now gone with this fading test checking for the effects of a gloss optimizer overprint

    Paper Fading Test Epson 106 - GO overprint
    Total Lightness increase of CMYK patches (Range from 0 - 255)
    (measured with a scanner, delta via the histogram vs. a copy kept in the dark)

    The overall trend remains, the GO overprint slows down the fading of the 106 inks, the unprotected black shifted just by 4 within 15 weeks, this compares to lightness increase of 7 within just one week of the HP 727 dye black - see the separate test here
    https://www.printerknowledge.com/threads/refilling-canon-with-oem-ink.10712/page-12#post-114117
    This makes a huge difference - the Epson ink is better after 15 weeks than the HP 727 ink after one week.
    I'm stopping this test here, the GO was supplied by the German octopus-office ink supplier, the GO of other suppliers may perform with different results, I already see a visible difference in gloss between this GO and the InkTec GO, the impact onto the fading performance may vary as well.

    @Ink stained Fingers, Your GO tests were very interesting, but what became clear to me is your GO worked well at the start as it did in my test, but as time went on it started to catch up to a point where it will make little difference..
    Please let it run a little longer... :)
    P.S. I used PC72-GO..

    Thanks for your input @The Hat , that's a good point - I'll place the targets back into the environment in a minute. There was quite some sun in the last weeks, and the patches are directly exposed to it. I could imagine that the GO may just reduce the impact of ozone but not filter the UV radiation very much

    Cyan is the weakest ink at this time, photo prints would get lighter overall with a color shift to red. These patches are placed outside, on a recessed balcony, indoor performance should be much better.
