imagePROGRAF PRO-1000 - Printer printing wrong colours - particularly blue

[sallymason]

My Canon Pro 1000 printer has suddenly started printing colours incorrectly. The colours are generally muted and  particularly noticeable with blues / turquoise.  Whatever compensation I make in the edit, just makes it worse.  I'm on a Mac and use Lightroom.  The same thing happened a couple of years ago and an OS upgrade and re-installing the driver resolved the issue.  This time I've tried the following to no avail: checked ink cartridges (genuine Canon), Print head alignment, Nozzle check, monitor calibration, upgraded from Ventura to Sonoma, removed printer, deleted printer driver, reinstalled printer driver, reinstalled printer, restarted laptop - but still the print colours are incorrect.  I have also spent 2 hours on the phone to Canon and had my case escalated - with no solution. The guy at Canon seemed to think there was a compatibility issue with Sonoma and that it was an Apple issue, but the problem arose when I was still on Ventura after 2 years of working perfectly, so that's not the issue with me.  I'm at my wits end, so any help or advice would be greatly received.  Thanks in advance.

Ah...ok...I just printed from Lightroom on normal photocopy paper, selected Colour Management to be Managed by Printer, set the media type to plain paper and it's printed strong colours.  It's night time here so I'm looking at it in artificial light, but I can definitely see it's more like the iphone print than all the other insipid looking prints lined up on my table!  So what does that mean??

Could be an issue with your profiles then. Since you said not Canon paper you could redownload third party profiles. Which paper are you using?

[sallymason]

I'm using Fotospeed.  Have been using for 2 years + with no issue.

D'oh! I must of mistakenly hit 'Accept as Solution'.  We're not there yet!

We changed it for you. 🙂

Thank you, Danny 👍🏼

I'm not using Canon paper btw.

You could re-download and install the third party profiles if you think they are corrupt.

I'll try this.  It will, at least, rule out (or not) yet another possibility.  I'm wondering though, if it prints ok when the printer is managing the colours, that would then also point to the driver being the issue.  Sigh.

I think we are on to something with this. It prints betterr with "Let Printer manage colors". First this should be the setup when printing. This allows Lightroom (or whatever) to process the colors per the profile you setup in there. You want to bypass the Mac side of the processing as you don't want to reprocess an already processed image. You want the application processed data to go straight to the machine for final processing.

It has been a while since I have played with one of these small units. I believe the printer has an internal calibration that can be run like the rest of the pro line. When was the last time you ran that one? 

[sallymason]

Are you suggesting that it could be a case of double profiling? I did consider this possibility, but I'm not sure under what circumstances it might occur. As for the printer setup, I believe it's configured correctly. I've had two lengthy conversations with Canon specialists, both of whom took control of my computer and confirmed that everything is set up properly with Lightroom.
