CMYK in Photo

[jak]

I have many photos in RGB and when I go to print them, with a pro printer, they come out with the wrong color, usually darker as their equipment is cmyk. . I cannot find a way to convert them to cmyk in Photo. I must be missing something. In Designer, you can go to Shift-control-p and get to a cmyk setting change and the change of color is obvious. Is there something similar in photo.? One needs to see the difference as one works on the photo.

I found the preferences. I know you can set it to print ready in NEW, but when I bring in the RGB photo, it still says RGB on the upper ribbon (dashboard).

From the menu, Document > Color Format > CMYK (8 bit) will switch the document to CMYK. I don't think that's what you should do, though.

I think (though I am not an expert and have done very little with professional print services) that instead,

1. You should contact your printer and ask them for their profile for the printer and printing material you plan to use. Then install that profile on your system.
2. Then Add a Soft Proofing Layer adjustment to the top of your layer stack and select that printer profile from the list.
3. Then adjust your photo so it looks correct to you with that color profile.
4. Then hide the soft-proofing adjustment layer (this is important), and Export the image to the appropriate (RGB) output file, and send that to your printer.

Many photographers use professional printers, and many professional printers use CMYK, and I do not think that all those photographers are converting their images to CMYK. Certainly the services I have used, and the photographers I have talked to, have never mentioned doing that.

In the set of Affinity Tutorials for Photo there are several dealing with soft-proofing, which will provide further details of that process.
