Turn off colour management in printer
I've been trying to obtain a custom icc profile for a new paper where the manufacturer does not have one for my printer (Canon PIXMA PRO-100S). The instructions from the manufacturer (and everwhere else that I've looked) say that you have to turn off colour management in the printer (that is, colour management from C1 using a paper icc profule and "Printer Manages Colour" are both off). You can do this in Photoshop but I don't see any way to do it in C1. When I queried the need for this step, the manufacturer told me that all printers automatically apply a degree of colour correction independent of a specified icc profile and that it will be applied to a print out generated with "Printer Manages Colour".

Thanks for your reply Michael.
It looks like I have either not understood what CaptureOne does correctly or I have made a poor job of explaining the problem.
If at the "Color Profile Managed by Printer" step you select a profile from the dropdown that opens (which is a list of all the icc profiles you have loaded to the ColorSync folder) then CaptureOne and not the printer will determine the colour profile that is applied, namely the one that was selected (and you can see the effect of this if you open Soft Proofing).
If you do not select a profile then the colour management (if any) is applied by the printer. It is this basic in-built colour management that I have been told has to be switched off when printing a target for creating a custom icc profile. I posted this question to a photo website and got several unhelpful replies showing me how to turn it off in Photoshop!
It is of course entirely possible that C1 behaves differently and that if you do not select a profile in the printer then CaptureOne automatically acts like the manual turn off step in PS and that is why there is not an active "turn off" option.

Hi, I make Custom Profiles and have had several customers print my targets with the Adobe Color Printer Utility and Big Sur. I don't have Big Sur myself, but under Catalina you get a warning message to the effect that the ACPU app isn't secure and you can 'register' it and allow it to run. It will then run perfectly (despite what Adobe say).
I even have a web page about it:

You can also use Qimage One (Mac version) or Print-tool (Mac only).
Hope this helps,
Phil

Thanks Phil.
You have produced a superb website that needs to be more widely known about! I'll explore it more fully later to see if there are any tips on how to get rid of a magenta colorcast when printing mono images. I saw you recommended Print-tool, but it only supports Epson printers.
As mentioned in my post immediately above yours, I have downloaded and used Qimage One to print the targets.

Hi Billtils,
Glad you like my site!
I think, but aren't sure, that Print-Tool may support any printer? However, the associated QTR only supports Epson. I don't have a Canon so can't check.
Yes, B&W and colour casts are a pain! There are various reasons, with the most common being metameric mismatches from the coloured inks (as opposed to paper), however, papers with Optical Brighteners (OBAs) don't help either! Using ICC profiles doesn't help much, and I make them! The best way is to use a dedicated Black programme, such as Epson ABW or the Canon equivalent, which use mostly Black/Grey with some coloured ink to help with 'tone'. I think the Canon PSP may have that option, if it works with the Pro100?
Also work from Grayscale images, not from RGB.
Cheers,
Phil

Hi Phil
My editors of choice are CaptureOne and Affinity Photo, and I also have and use a copy of Canon's Print Studio Pro. As far as printing goes the default is CaptureOne, I don't use AP to print at all, and go to PSP for any serious B&W but not always with the best of success. Hadn't thought about going Grayscale - that just may end up being my weekend project :)
