Oh well, there are several possibilites - using the Fuji inks in an 3880 would require you to get refill cartridges anway. And then you would have all choices as well for pigment inks - third party - much cheaper - or you buy bigger 220ml cartridges for the bigger Epson LFP printers - like the Pro 4880 and refill into your smaller cartridges for the 3880. On those bigger cartridges you would pay less for the litre than for the 3880 cartridges. It's your choice, and your money

Two more samples after 7 days under the UVb bulb, this time I printed color bars.
1 coralgraph dye vs fuji DL dye on thin inkjet paper 120g

2 same inks on tecco resin coated photo paper (pearl 250g)

Here are the results of one more week of fading test using the bug zapper lamp. The Canon inks seem still not to be affected, but the IS inks have faded further. The results of one week of testing is here.

Here are the Canon inks. Upper left is Canon ink + Canon paper with no UV exposure. Upper right is the same inks and paper after two weeks of UV exposure. Lower left is Canon inks on Sihl paper with no UV exposure and lower right is Canon ink on Sihl paper after two weeks of UV exposure:

Here are the IS inks. Upper left is IS ink on Canon paper with no UV exposure, Upper right is the same inks and paper after two weeks of UV exposure. Lower left is IS inks on Sihl paper with no UV exposure and lower right is the same paper and ink after two weeks of UV exposure:

The blue/green vertical stripes in the faded B/W images are caused by shadows of the protective grid in the UV lamp:

It seems that the Canon OEM inks are superior in fading resistance, but they are also very much more expensive than refill inks.

I'm not so knowledgable about Canon inks, but Canon offers a wide spectrum of large format printers, ImagePrograf models, of which some can use dye and pigment inks alternatively. Similar to the situation with Epson inks buying a particular ink in a bigger cartridge and refilling the ink into smaller ones makes it much more affordable - the bigger the cartridge the steeper the discount on the price/litre. Such a deal works for Epson inks - Ultrachrome - for those who want to stay with Epson inks , at a much lower price than with small cartridges. I would assume that trick would work as well with Canon ink - somebody should try it starting with one ink.

I did that with the Prograf 6400 OEM cartridges and yes it is cheaper than the small cartridges (50% saving) but the savings are still much bigger with 3rd party inks..:)

Thank you for comparing canon OEM "chromalife", Peter .. I am too cheap for these ..
But as inkstainedfingers proposed I will look for bigger canon dye carts.
There are BCI-1401 / 130ml (for w7250) and BCI-1411 / 330ml (for w7200, 8200..). If "bci" is formulated like the old bci-6 my ip4000 is waiting. There was a change of magenta and photo black from BCI to CLI - but I don't know how big the difference is.
The smaller ones cost around 40€ for 130ml. TheHat, Carts for 6400 are pigment, I think?

I'm interested in canon OEM not only because of color matching and longevity. After I had at some burnt printheads I am arguing with bubblejet thermo printheads. Well, epson cloggs but canon burns, if you don't pay attention. And since I read about non compatible piezo epson inks for canon and boiling points of fluids I am more aware of these aspects as potential "bubble jet nozzle burners"..

The Hat, thanks for confirming that the idea of draining bigger cartridges actually works for Canon; there is definitely the wish of some to stay with OEM inks but trying to find a tricky way to save some money, some may want to utilize the good UV performance of OEM ink with a printer which does not take the more cost effective cartridges, and some other just don't care and refill with the cheapest ink available. Whether they all save at the end.....o.k., that's another thread..
When it comes to fading, I did some tests, partially reported already before, I tested a
'UV resistant' ink from US/Amazon, that actually was a fast fade ink, useless in this respect.
I tested an ink from China/Alibaba 'UV resistant', CMY perform somewhat better than Coralgraph dye inks, except black, that has turned into a yellowish brown after 3 weeks, by far the best performing dye inks , non Epson OEM, are inks out of cartridges for the Fujifilm Drylab printers DL100 etc, virtually no change yet in 3 weeks out in varying springtime whether, sun, storm, humidity, but no direct rain. Those inks are definitely a magnitude different to all the other inks tested, and run at about 25% of original Epson inks (in small cartridges). In a way they are OEM inks as well, but by Fujifilm.
Epson does not offer at all dye inks in larger cartridges for their large format printers.

If you choose to use OEM or 3rd party inks in a Canon printer it’s debatable whether one will make the print head last any longer then the other, that said.

When you use OEM dye inks you are paying a premium for the privilege and for that you get good colours and a reasonable amount of print longevity and that would seem to satisfy quite a lot of end users, but.

When you use 3rd party inks your colours are slightly different and the longevity of your prints is, well let’s say a lot shorter that OEM inks are, and here’s where that But come in.

You can print all day and a lot more besides (cost wise) which most refillers love to do, and the colour issue becomes a delightful work around and the longevity is overcome by a simple reprint, and if your print head does roll over and dies, you’ll have saved enough to get several new ones.

It’s a matter of choice which inks you choose to use but one thing is for certain your print head isn’t going to last any longer just by using OEM ink, that’s my opinion.

My latest print head didn’t die from exclusively using 3rd party ink but from a mechanical problem caused most lightly by wear and tear..

There is still a "But" more: Sure you can reprint faded prints for almost no costs - but how often would you really do this? And more important: what about prints you give away (not to speak about purchasing them) - would you like to receive photos as a gift which will fade in less than one year, or even one month?



My fading test under the desert lamp continues, now with epson OEM K3 included:
(6 days under UVb bulb)

1 FujiDL (printed with R285)

2 coralgraph dye (epson R800)
coraldye-R800_onTecco250pearl_6tageUVb.jpg
- both on tecco photopaper pearl 250g

3 FujiDL (r285)

4 Epson ultrachromeK3, printed with a 3880
epsK3oem-3880_onFAbaryta325gl_6tageUVb.jpg
- both on FA baryta 325g
(the blank side isn't fade to white, but simply a printing error, I pressed "cancel" for no reason, still learning the settings of my new 3880)

I will certainly do more comparisons including OEM K3 ink, because while they are fading much lesser they are probably not dateless (as some are claiming)
