The PDF Profile can preflight any open document in Acrobat for spot colors. You can also set the requirements of which spot colors are allowed and which are not.

Here are the steps to set this up:

• Select an existing PDF Profile you want to edit or create a new one through Manage > New.
    
• In the PDf Profile editor select the category spot color.
   
• This category has a number of checks that are related to spot colors. For example the first check will detect any spot color used in this document. 
    
• The check most likely to be used in this scenario is the fourth one "Number of seperations is'.
    
• This check allows you to determine the color you want in the document and report any other seperations.
    
• First set the number of seperations you want to allow, for this purpose we don't allow any seperations thus select 'More Than' from the dropdown and fill out '0' in the field.
    
• Then specify which seperations are allowed. Enable the following checks:
  • Don't count process colors (C, M, Y, K)
  • Don't count spot color 'All'
      
• Set the parent check to error.

This PDF Profile will error out any seperation used in the document.
When using the Enfocus Navigator to show the preflight results the following error will be produced (when spot color is found):
"Document uses 1 seperation, should be less than or equal to 0".

To solve this problem (converting the spot color to CMYK) use the Solutions section of the Enfocus Navigator. 
It will provide you with the solution "convert spot color to equivalant CMYK color". Fix this for all problem objects and restart the preflight.

No more seperation error will show up in the preflight results.

The Global Change panel can search for any document spot color and remap it to another spot color.

Here are the steps to set this up:

• Open the Global Change panel
   
• Select the action 'Remap Color'
    
• In the From field choose 'Color in the drop down list and load the spot color you want to change > Document spot colors
    
• In the To field choose 'Color' in the drop down list and load the spot color you want it to become > e.g. PANTONE Process coated
    
• Set the global change 'Run' options

Run the global change and search for the objects that have been changed.
Note:
This global change can also be used to convert any seperation, DeviceN or NChannel color space to e.g. Device CMYK.
Or to convert any device CMYK color to 1 seperation.

Both examples described above can also be executed with an Action List.

You can create a new Action List or use the global change panel to save it as an Action List (you find this option in the 'Run' section).

The actions related to spot colors are:

• Select spot color
• Select spot color by alternate color space
• Remap spot color
• Rename spot color
• Change spot color suffix
• Convert spot color to equivalent CMYK values
• (Convert process to spot color) > the opposite direction
• Check spot color by name
• Check spot color suffix
• Check number of spot colors
• Check spot color by alternate color space
• Check spot color equivalence

Example = Check alternate color space of spot 'Wine Red' is CMYK or gray
Select spot color by name (Wine Red)
Check spot color by alternate color space

To allow easy access, you can assign the Action List to a QuickRun button so that running it on the open document requires only one click.
