I got the profile for Fotospeed Smooth Pearl 290 using Prink inks on my MG5250 back earlier this week, installed it and printed the test image I used in Post #9 from Capture One Pro with the profile. The results are pretty much identical to that post, maybe slightly different colours (actually closer to the results from the Permajet profile in post #14 than I'd thought):
Now I am REALLY confused about this! I had assumed that, whatever weirdness is going on between the ink and the printer would affect the printing of the patches too, and the resulting profile should correct the problem (note, I have a relatively low understanding of how colour management works!). But this seems to be not the case.
So far I’ve had suggestions (some from me) that
a) it’s the paper
b) it’s the MacOS latest version, which is alleged to treat all printers as AirPrint if on WiFi
c) it’s because the printer is no longer supported on MacOS so the driver won’t work
d) it’s because I don’t have the proper profile for the paper I’m using
e) it’s the printer
f) it’s the ink…
I’ve been trying to eliminate these, systematically:
a) the problem occurs with 4 different paper types, two good quality, two cheap, so I don’t think it’s the paper.
b and c) the problem occurs even if I print from the Windows machine with a USB connection (just basic printing; I don’t have any proper photo software allowing custom profiles on that machine), so I don’t think it’s the Mac. Also, there is a proper driver on the Mac (version 16.10.0.0) and no sign of any AirPrint driver.
d) I’ve now tried it with a Permajet profile for their Matte Plus 240, and the Fotospeed profile for Smooth Pearl 290. The Permajet profile did have an effect, but the result was blueish rather than greenish. The Fotospeed profile also made only a difference, but not an improvement.
e) the printer appears to work; it gives good text and plausible colour images on plain paper, though I suspect there is a colour cast in there (definitely for black and white).
f) I guess the ink is a strong candidate, though the (different) Prink ink for amyCanon MG6350 worked very well, and folk on here who have used the ink report good results. Unfortunately, to properly test this, I’d have to fork out around £70 for a set of Canon inks, which would be wasted if it ultimately turned out to be the printer!
I was nearly at the point of buying a new printer (thinking of a Canon G650), but apart from the fact that the MG5250 appears to work for “normal” printing, the paper handling for the G650 (all paper in the rear tray, no cassette) means it will be unacceptable for normal printing (no way are we going to load plain paper every time, nor leave paper sitting exposed in the tray). I don't want to buy another cartridge-based printer, the excellent-looking Epson ET8500 is over £500, so an "investment of £70 or so for Canon inks is now looking more plausible!
EDIT to add: Prink has not responded to a support request, and Fotospeed has also not replied to my request for a bit more information. Permajet was great in giving me a long phone call, but I was really confused by what the techy guy was saying, and some of it seemed just plain wrong (eg he told me that if printing from a Mac on Ventura to any printer, the Airprint driver is used, but I don't have an Airprint driver for this printer, and anyway the problem still occurs from Windows).
