How to convert colours automatically

Then you must build it that way.

Hey

Sounds to me like you're using an RGB colour space (you can check by looking at the document tab, or by choosing File > Document Color Mode).

You may also want to look at your preferences, and the Appearance of Black category—change your printing/exporting options to Output all backs accurately.

One last thing—and I'm only mentioning this because I have seen it before (it's not a reflection on my perception of your ability); make sure that you're not using the Registration black, as that's intended to use all colour plates.

Hope that helps!

If this has answered your question, please mark it as answered.

In one click? No.

Why are there more than 2 colors in your artwork? Set up Global swatches in the beginning and use them.

it actually does this automatically if you are working in CMYK color space.

Have you checked your color space ?

Also, if you want to see which colors exist in your artwork you can check Separations Preview window to enable Overprint Preview check box.
