When measuring printed samples to find the best matching CxF/X-4 color definition, it is advisable to collect these CxF/X-4 colors in a separate library file. The colors can then be used as certification targets for print validation measurements or exported to ASE format and then imported into Adobe swatch palettes.

1. The spot colors that are found to be best matches in the CxF/X-4 library file will be added to a new CxF/X-4 file by default. If they should be added to an existing CxF/X-4 file, click and select this file.
   
   

   

   
   
2. Having measured a printed sample, the best matching CxF/X-4 color is selected automatically. If you do not want to use it, select another color from the list of CxF/X-4 References (e.g. the second best).
3. Click to add the selected color to the list of CxF/X-4 Certification Targets on the right.
4. Measure additional samples and add the matching CxF/X-4 colors to the list. Repeat this until all printed samples have been measured.
   
   

   

   
   
5. The CxF/X-4 data you have matched to a measurement can be replaced as follows:
   1. Select the color in the list of CxF/X-4 Certification Targets (right).

      The best matching CxF/X-4 color is selected automatically on the left.

   2. Select a different color in the list of CxF/X-4 References (left).
   3. Click the button.
   
   

   

   
   
6. When finished, click to save the list of CxF/X-4 Certification Targets as a CxF/X-4 file.
   
   

   

   
   

   The new CxF/X-4 file can be used as follows:

   • Validation:

     Load the CxF/X-4 file to easily measure the spot colors against the CxF/X-4 definitions. See Print Validation (Certification) for more details.

   • Color exchange with Adobe CS:

     Export the CxF/X-4 file to ASE format. See Using ASE Files for Data Exchange with any Adobe CS Application for more details.
