For one thing there is no Custom CMYK in Illustrator. Custom CMYK is a killer feature, especially when working with screen captures and scanned drawings. Second, the fact that the conversion requires two commands (one for Color Settings and one to convert to CMYK) is not intuitive. You will probably have to take a guess that “some form of SWOP” will be the simulation space set at the digital printer… Not all CMYK profiles are created equal, even within the same colour space. Then there are different rendering intents. There is also the possibility to converting into “any” CMY how to convert rgb to cmyk in illustrator without changing colors in adobe illustrator how to change CMYK to RGB in Illustrator. Step 1: Select the objects you want to change colors. Hold down the Shift key to select multiple objects, or if you want to select all objects hit Command + A.

If they did, then convert to that specific profile (Edit > Convert to Profile). Generally I would recommend against it for printing an image. Just save as JPEG in max quality, and print that. Keep it RGB with the profile embedded. With an embedded color profile, their printing software can accurately convert it as needed. Old versions of Adobe Illustrator would convert any RGB file the main color mode configured when creating the Illustrator file upon import (such as CMYK). I am not sure about the new versions. But it is not a problem to have an RGB file inside if your output is a controlled PDF file. Sometimes is better to have an original RGB file. The blending mode could be changing because there's a color shift caused by going from RGB to CMYK. Assuming you'll be printing it on paper, will it be a (a) home inkjet printer or a (b) commercial press? If it's (a) an inkjet printer, you can leave it in RGB mode. If it's (b) press, it will require the the CMYK mode. .
