Adobe Photoshop/mix & match CMYK channels in PS


Hi Kevin,
Is it possible to take the Black sep/channel from image-A and paste it into image-B's Black channel, so I end up with one image that has the K from image A + the CMY from image B?

If yes, how do I do this? I use Mac OS-Maverick & PS CS4.

Thanks a million in advance for your answer (which I hope is yes, it's possible, with an easy way to accomplish this!)


Hi Marianne,

It's very easy. Simply go to the channels panel and click on the Black channel in Image A. Next do a Select All (cmd+A) and copy the image. Then go to the channels panel in Image B and select the Black channel. Paste into the Black channel in image B and you are all set.
