I am in the print field and relatively new to photo shopAdobe Photoshop. 

I have a lot of situations where I would like to have CMYK over a transparent background. 

We place .psd files into illustrator for packaging graphics. Example (Crest toothpaste carton). What I am trying to achieve is a trap of CMYK in an image to a vector or other raster element in an illustrator file. The only way I have been able to achieve this is to use 2 separate images. A CMYK image set to darken or overprint in illustrator and an all white transparent image underneath set to knock out the background.

The only way I have been able to achieve this is to use 2 separate images.

  • A CMYK image set to darken or overprint in illustrator
  • And an all white transparent image underneath set to knock out the background.

I know I can achieve this in one image using spot colors but have not been able to remove the knockout attribute associated with CMYK in a psd. Does any one have a way to let CMYK in a .psd be transparent in some areas and opaque in other areas?
