I'm drawing cartoons in black & white for a publication. I've been told that I must make the black 100% and the CMY 0%. After I scan the image I convert it from RGB to CYMK mode but I can see in the channel's palette that it has colors mixed into the black. If clear the CMY channels it image loses detail. I've also desaturated the image but it doesn't seem to do anything.

So is there an easy way to remove the CMY channels without losing part of my image?

Just use grayscale, you don't need CMYK for that.

I can't use gray scale because I forgot to mention I'm colorizing the cartoons in Photoshop. They're black and white outlines drawn in pen and ink then filled in with colors.

Image>adjustment>threshold may be enough to get you where you need to be.

I found a solution I don't know if its the best way...

in the channel palette I select all, copy, and paste the cymk channel into the black channel and then delete the contents of the cym channels

Before starting to colorize the image you can duplicate the layer.

The top layer can be converted to black: By deleting the contents of the
CMY channels and change all grey values to 100% black via levels. Remove
all white and make it transparent.

Rename the bottom layer.

Now colorize the bottom layer.

Afterwards put the bottom layer with all 100% K contents on top.
Flatten and save.

Record the actions which you need to for all images and make it an action
for the next time.
