Very good !
I cleaned a PGI-72GY and filled it with octo magenta, but I had the strange nozzle check again after four 10x15 cm and one A4.
Can't remove all color from the PGI-72M.
Will try hot water.
windex 10+ times in and out 12 ml.
first time i think i did 4 times in and out that did not help

While researching differences and benefits of Windex versus liquid dish washing soap with printer ink, I found an article @mikling might enjoy on surfactants in inkjet inks:

https://www.researchgate.net/publication/264858812_Surfactants_in_Ink-Jet_Inks

I never underestimated the complexity.
What I read between the lines is that not all additives are compatible and there can be reactions between inks of different manufacturers.
That's why I try to clean a cartridge as much as possible when switching from one 3th party ink to another.
Unfavorable reactions are supposed not to occur with OEM.

In practice I observed a slight clogging on my PRO-9500II (removed after 1 cleaning) when changing a cart with PGI-9Y (C-7062P) against one with Octoinkjet PGI-72Y.
I won't buy new ink for the 9500 anymore and replace some of the inks with PRO-10 and reprofile.
Will keep a not so perfect printhead until this ink transition is done and I mount my last printhead (the first brand new I ever had).

We know that already, and thanks for helping to solve it :).
I loaded the PRO-10 again with 9 Octoinkjet + PC CO and will see if flushing is a long term solution of the "magenta problem".
Same eventually for the red.

People who complain here on the PRO-10 3th party inks forget how lucky they are with the actual offerings of Precision Colors and Octoinkjet.
Both sets are colorwise very close to OEM and have a black level where I could only dream from with the PRO-9500.

Personally I think the chance to find better inks somewhere else are very low.
José Rodriguez already shut out a well known US provider.
Octopus-office.de is way too expensive and has no chance against PC.
Inktec is cheaper, reserve candidate in case of a full blown trade war.
For my own peace of mind ("why didn't I buy the holy grail ink from the start :ep") I made a short comparison between

Canon OEM (red)
Octoinkjet + PC CO (green)
Precision Colors CMY,PBK,CO + OEM R + Octo PM,PC,MBK,GY (blue)

The profiles with my lowly Colormunki do maybe not have a high precision, but they show IMO enough.

Paper: Canon Photo Paper Plus Glossy II PP-201

L=50:

L=05:

L=90:

IMO all 3 combinations have ample gamut and black level.
Color strength is no reason to buy OEM.

Note that Octoinkjet does this without adding OEM (Precision Colors needs OEM Red).

The gamut of PC seems indeed to be larger to the green and the blue as suggested in the published profiles.

Black levels are impressive too.
The PC black patch with PC ink in the first Colormunki chart measures L=1.5, 0.5, .8 where OEM is L=2.7 0.2,-1 and Octo L=3.0,0.6,-0,2.
The scratch sensitivity of Octo standard PBK is IMO no show stopper, with the coating and after drying it resist normal use.

More difficult to evaluate are the gloss differences.
As far as I could observe both on test prints and real photos a 100% equal gloss on glossy papers is only reachable with OEM ink (on condition there are no white spots without ink - the "full" coating setting works only partially, sorry Canon).

This is partly caused by the 3th party CO but also because the glossiness of each 3th party color is not the same as the corresponding OEM. Only Canon knows exactly how much CO has to be applied.

But compared with what I had for the 9500 (the PC advanced inkset) all colors, even the red and magenta, have a good gloss. The PC PBK is so glossy it shines through the CO.
BTW Canon calls this Color Optimiser, the idea is the slightly hazy layer should absorb stray light.

On semi-gloss and in particular luster surfaces all inksets reach a very even reflection (and are 100% scratch resistent)
This was already the case with the PRO-9500, only the red and magenta were duller.

I printed several photos on both printers to compare.
After calibration with the Colormunki colours are the same, most people do not see any difference in frontal sight or framed.
In reflection the worst PRO-10 combination is still much better than the PRO-9500 (with 3th party ink).

Dear PRO-10 refillers, be grateful to Canon for this printer and to @mikling and @websnail for their inks !

The Achilles heel of the Color Munki Photo for printer profiling is that the sensors are fooled by the UV wavelengths reflected by the OBAs used to enhance the “whiteness” of the paper. Those brighteners are widely employed nowadays, not only in cheap brands of glossy stuff but even on luster or matte products of well known manufacturers.
If you want to check with a decent accuracy the gamuts of custom profiles made with a Color Munki, use papers with the least amount of OBAs possible.

One fast way of assessing roughly by eyesight the amount of brighteners present is by illuminating the paper with a UVA tanning lamp or another source of UV light,
If a blank sheet of paper looks yellowish with this light, the amount of OBAs is marginal or zero. If the paper turns a vivid violet then it has plenty of them.
I discarded Canon Platinum for this reason and I suspect that all RC glossy stuff from Canon is similar. Instead, Ilford Smooth Pearl and Epson Pro luster are fine, No violet fluorescence visible with the naked eye.

My intention was not to make exact measurements, only a comparison.
Maybe the Canon paper was not the best choice, but I wanted to use a commonly available reference i.o. the Aldi paper.

I am an amateur, as most of the people who read this forum to find information - although input from professionals is most appreciated ;)- and reason that way. A pro buys OEM ink (and an expensive calibration device).

I am a big fan of Ilford Smooth Pearl, on this paper the prints have 0 gloss difference, 3th party is indistinguishable from OEM.
No adherence problems either, so the Octoinkjet Standard Black is a very good buy.
As most of the other inks too IMO.

I would prefer to continue with these inks, and will help to sort out the issue reported recently.

@Artur5, please help me on this one I’m not quite sure what you meant by the colour “Vivid Violet”, I turned out my lights and exposed Aldi Photo Paper to a UV light used for killing flying insects, and the Photo paper surface was the same colour as the UV light…
