Fellows, I have a problem:

In the grey background above the birds head you can see horizontal bands.
On high quality it is less but still visible.
Strange enough on the cheap Action paper with Hagaki settings everything is OK.
So I don't think it is a paper transport problem.

Any ideas ?

Those bands are because your ink flow is not 100% in time you gona burn your print head.

The ink flow is my concern too, but I wonder why it always occurs on the same place.
I do stress tests with every ink.

By lightening the grey background a bit the banding disappeared.

Interaction with CO, in general a temporary "slippery" condition of the ink can't be ruled out.

Based on what I've read, a blurry or slightly milky appearance of the CO should not be a negative.
Canon designed this coating to absorb stray light, not to reflect it.
Instead of counting on the overlay function to optimize the gloss, IMO it is better to focus on equal gloss of the inks.
Changing to OEM PBK helps a lot as indicated on the Octoinkjet site (it enhances the gloss of my 9500 prints too).

I don't have any Octo CO anymore to test again. It was less effective in covering heavy gloss differences, but from what I can see on test sheets it performed well on the non-black surfaces of glossy and luster papers (I see no blur at all).

Obviously OEM ink on Platinum PRO gives the best results, but refilling means compromises.

IMO in Europe you can find better quality for less money than paying the expensive shipping from the US.

Canon ? + 3D, CR-10.
it’s a software related issue, either from the driver or the program that you use to edit/print. If it’s not visible with hagaki paper setting, that seems to leave the driver as the most likely culprit ?
I also reckon that’s the mostly cause, think about it, same ink, same image, different surface, the only change is the driver software..

I did some new tests (plain paper M, Y, R) in Platinum N standard.
Could see one slight band in the R.
Disappeared in Glossy II settings (but the colour was a tad less bright red too).
Also the band was darker, not suggesting a lack of ink.

Driver settings seem to be very important.

You can pay the price for ink from Canon or suppliers who claim 100% compatibility, or do some tests yourself and print cheaper.
Same for paper.

I always have printed on Aldi and Sihl glossy paper with Platinum settings for the maximum gamut and won't change at this moment.
Recently switched to standard quality, high doesn't change anything on the colours but has sometimes a tad more details (only visible with a magnifying glass), OTH it is much slower.
Didn't see any banding again.
Nozzle checks are 100% clean, 651-700 pages printed (80% A4, some A3 and 10x15cm).

Since I have 3 inksets :mad: I made the best selection with rationalisation in mind (although I will keep one OEM PGI-72 set for reference):
  • PM: Octoinkjet
  • PC: Octoinkjet
  • Y: Precision Colors SE
  • M: Precision Colors SE
  • R: OEM
  • PBK: OEM
  • C: Precision Colors SE
  • CO: Precision Colors original edition (have SE on stock)
  • MBK:Octoinkjet
  • GY: Octoinkjet
After expiry of the PC CMY I will continue with C and Y Octoinkjet and M OEM (octo M maybe later).
I had some extra costs for OEM ink and myUS for shipping Precision Colors, and probably will not use some of the inks, but that's a small price for finding a set very close to OEM for a much lower price (in Europe).

The surface of Aldi and Sihl paper (comparable to Canon Glossy II) is not of the quality to justify OEM CO. I don't see a difference with PC CO (what @jtoolman told recently on youtube maybe applies to better papers).

When eliminating the highlight warnings automatic CO settings give a 100% equal gloss, when this is not possible everywhere the full settings work most of the time. In general the gloss is better with this setting and I have enough CO.
It always frustrated me I couldn't reach this with the PRO9500 (although the inks were not as good, I bet loading PRO-10 ink would solve most gloss differences if not all using luster paper).

Compared to the PRO9500 II it seems to me the PRO-10 uses less ink for purging.

Very glad until now to have changed to this printer, I couldn't imagine better.
