I thought I read somewhere once that you can swap a channel. For example, you make a copy of the yellow channel, delete the black channel, and make the yellow copy be the black channel (i.e., the yellow copy now prints black ink). I’ve done my requisite research and can’t seem to come up with an answer.

thanks!

There are several ways of doing this including copy and paste (via a temporary channel).

thanks!

But if I just copy and paste – now I have two yellow channels. How do I take that channel and make it black (or magenta, or whatever…)? Thanks man…

Try this:
"Image/Adjustments/Channel Mixer" from the pulldown menus.

I’m not sure why you’d need to do this. If the idea is to swap the image between K and Y, copy and paste will do. Obviously I don’t understand your objective as well as I thought.

If you want to arbitrarily assign inks to channels, you’ll need to use Spot Channels.

Other techniques you may wish to experiment with are Split and Merge Channels.

In the Channels palette, go to the Yellow channel, copy, then go to the Black channel and paste.

This is the clumsy way to do it, though. The Channel Mixer command is faster and easier, and offers far more control.
