Changing the color mode of a document


    You can change the color mode you want to work in depending on how you will output your document. If the document will be printed, you should work in CMYK color mode; if it will be viewed onscreen or otherwise projected with light, you should work in RGB mode. You can switch back and forth between these color modes without losing information.

    Note: Most raster effects in Illustrator can only be applied while you are in RGB mode. Also, some file formats, such as JPEG, automatically change the mode of a document (in this case, to RGB).

To change the color mode of the document:

    Choose one of the following:

    • File > Document Color Mode > CMYK Color.
    • File > Document Color Mode > RGB Color.
