  1. After working on an image that needed to be converted to CMYK color mode, I found that the vibrance adjustment layer I created could not be converted.

    When converting to CMYK, Photoshop gave me the message: “Changing modes will discard an adjustment layer; change mode anyway?”

    It gives the options: Ok, Cancel, Merge. If I choose merge, the image appears with the correct adjustments I made, but all layers are then merged into one. If I select Ok, then the layers are preserved but the image doesn’t appear with the correct vibrance adjustments. It looks like vibrance adjustment layers aren’t allowed in CMYK images… so to convert you’re stuck doing the adjustment in RGB, then merging when converting to CMYK.

  2. James,
    To avoid this you’ll want to flatten your image prior to converting it to CMYK. I’d recommend saving a layered .PSD document in RGB with all your corrections to return to then use the Edit>Convert To Profile command to perform the RGB to CMYK conversion. Within the Convert To Profile dialog, there is an option to flatten layers before making the conversion.

    It is generally discouraged to change color modes without flattening adjustment layers as it can cause unpredictable shifts in the way your adjustment layers are applied to the image.
