If you want to preserve the CMYK colors, you can create a copy of the object or image and convert the copy to RGB, or you can use a color conversion tool that preserves the CMYK colors. Make sure 1. Open the Adobe Illustrator file you wish to convert. Right now your document may be in the RGB color mode as shown on your document tab in the top left-hand corner. 2. Navigate to File > Document Color Mode. Choose the CMYK color option. Your CMYK conversion is done! 2. Convert RGB To CMYK For Individual Elements RGB stands for red, green, and blue, and it is the color mode used by digital screens, such as monitors, TVs, and smartphones. RGB colors are created by mixing different amounts of light from What Is CMYK. CMYK, which stands for Cyan, Magenta, Yellow, Key (Black), is the color model for tangible, printed materials, or shortly – CMYK is print colors. In this case, the printer creates images by mixing CMYK colors to varying degrees with ink instead of digitally as it is with RGB. This is called subtractive mixing. To convert your RGB document to CMYK using Adobe Illustrator, simply navigate to File -> Document Color Mode and select CMYK Color. This will change the color format of your document and restrict it to shades that are exclusively within the CMYK gamut. The following is just a written overview. I need to import PNG image (because I need to place object extracted from the background). And here I step on the unknown area because I actually don't know will Illustrator automatically convert PNG image colors (which is RGB only format) to CMYK. In Illustrator's Color settings, working CMYK profile is set to "U.S. Web Coated (SWOP) v2". I have had this question for several years and never got around to asking it. I am very familiar with converting RGB files to CMYK in Photoshop. I expect some duller color shift when I do this to the smaller CMYK gamut. Usually it is not a major issue. With Illustrator it is different. As an exa AWYRiXq.
