CxF/X-4 color definitions can be assigned to the spot colors in a PDF/X file if missing or incorrect. Color definitions are assigned automatically if a suitable CxF/X-4 library file is specified. You can extract or remove CxF/X-4 color definitions and view the spectral curves and metadata. It is also possible to change the ink sequence and to extract the embedded output intent profile or to embed an ICC profile if missing.

1. Load a PDF/X file with spot colors in one of the following ways:

   • Drag the PDF file onto the ORIS CxF Toolbox window.

   • Click on the left, then click on the right and select a PDF file.

   • Use and to successively load all PDF files available in the current folder.

2. A message appears if the PDF file has no embedded output intent profile. In this case click and select a suitable ICC profile. Otherwise it will not be possible to assign CxF/X-4 color definitions.
   
   

   

   
   
3. Examine the data stored in the PDF/X file (output intent, CxF/X-4 data, ink laydown order).

   Click to view the spectral curves and metadata for the selected spot color. Editing the data is not possible. Click to return to the dialog for editing PDF files.

4. Add, correct or manage the data in the PDF file as you see fit. See below for more details.
5. Click to save your modifications to this PDF/X file or as a new file.
