How To Preserve Spot Colors in Photoshop (version 6 and higher)

The first thing you do, is to open your Channels palette, go to Window > Channels. In the Channels palette menu you will see that Yellow is the channel which has the most color for the star. So drag yellow channel thumbnail onto the New Channel icon at the bottom of your Channels palette. A new channel called Yellow Copy will appear in the Channels palette. Now, don't worry if your graphics looks black and white, this is because you are not viewing all of the channels that compose your image, but only the Yellow Copy channel. Just click on the CMYK thumbnail in order to see all of your colors again. Now that you have an additional yellow channel though, your colors will look different, but still don't worry, we have not finished yet.
