Yes. A separate copy of the original RGB image converted to CMYK and 
the same steps as noted previously harvest the K channel. Once the K 
layer is created in the layer stack its blend mode is changed from 
Normal to Multiply and a layer mask is added, enabling one to 
selectively apply the effect.
