How To Change RGB To CMYK In Illustrator

The best way to convert RGB to CMYK is to select your colored object, select Window > Color, and click the options link in the top right-hand corner of the Color panel. Select CMYK and adjust the color in the Color Picker.

Here are the various ways and steps to convert RGB to CMYK in Adobe Illustrator:

1. Convert The Illustrator Document

If you are sending your design file to print, and your Illustrator document is in RGB, you will have to change your whole Illustrator document to CMYK.

Here’s how you do it:

The conversion process is straightforward in Adobe Illustrator:

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.

3. Adjust Colors

Although you have changed the document color mode from RGB to CMYK, that doesn’t help you adjust the colors in your design. Although the color mode is already in CMYK, the shades and tones may not be accurate. You will have to check and adjust each of the colored elements. Here’s how you do it:

Select the object with the RGB color.

Open the Color panel by selecting Window > Color.

What Are RGB and CMYK Color Modes

Wondering what are the main differences between RGB and CMYK color modes? RGB (Red, Green, Blue) operates in an additive color process, typically used for digital device displays like computer monitors. 

CMYK (Cyan, Magenta, Yellow, Black) employs a subtractive mixing of colors, primarily used for color printing.

RGB Color Space vs CMYK Color Space

The RGB color space offers a wider range of colors by mixing colors of light. The CMYK color space, on the other hand, combines colors of ink and is used in color printing. You might notice different colors when switching from one to the other.

In general, RGB colors always look brighter on screen and when converted to CMYK, the colors will look darker.

Why CMYK Over RGB for Printing

The best option for high-resolution, high-quality printing is the CMYK color modeCMYK values are tailored for color printing, giving you better control and better results.

Your print shop and printing company will thank you for providing files in the right format.

Subtractive Colors vs Additive Model

The subtractive colors in the CMYK model mean that colors are mixed using ink, whereas the additive model in RGB mode involves the mixing of light. Your final product will be more accurate in CMYK.

Spot Colors and ICC Profiles

When you’re working on high-end projects, ICC profiles can help you manage color profiles for better accuracy. Spot colors, like Pantone colors, can also be converted to CMYK using the Edit Colors option.

Issues to Watch Out For

  • Rich Colors: RGB has neon and rich colors that CMYK may not replicate.
  • Color Changes: RGB colors might appear differently when converted to CMYK format.
