Matching Colors and Creating a Profile

Match the golden sample colors to the colors of the image displayed in the Before Color Matching section, and then create a color profile.

To match colors and create a profile:

  1. Check the profile that was selected in the settings used to print the PDF.
      Note:
    • The name of the setting to check varies depending on the DFE type.
      • For Fiery, the name of the setting is CMYK source. To change the CMYK source, open the Job Properties dialog and select COLOR in the left pane.
      • For the TotalFlow Print Server, the name of the setting is CMYK input profile. To change the CMYK input profile, open the Job Properties dialog and select Color in the left pane.
  2. In the Reprint After Color Matching section, select the CMYK source profile checked in step 1.
      Note:
    • To add a profile, select the Add button (Add button), and then select the profile you want to add.
  3. Check the rendering intent that was selected in the settings for printing the PDF.
      Note:
    • The name of the setting to check varies depending on the DFE type.
      • For Fiery, the name of the setting is CMYK rendering intent. To change the CMYK rendering intent, open the Job Properties dialog and select COLOR in the left pane.
      • For the TotalFlow Print Server, the name of the setting is Rendering intent. To change the Rendering intent, open the Job Properties dialog and select Color in the left pane.

  7. Check the color deviation on the color deviation map.
    1. Select Show ΔE Map.
      The color deviation map is displayed, and the button label changes to Hide ΔE Map.
    2. Check the deviation of colors.Checking the deviation of colors
        Note:
      • The color deviation is calculated by subtracting the value of paper color and truncating the decimals.
      • The brighter area in the map indicates the color of a larger deviation.
    3. Select Hide ΔE Map.
  8. Optional: Save the files containing the original data and the scanned golden sample data.

    3. Select the folder where you want to save the original data and the golden sample data and click Select Folder.
      The application saves the original data and the golden sample data to the selected folder.
  9. To save the profile, select Save on the lower-right side of the Color Sample Matching dialog.
      Note:
    • The format of the file name assigned to a profile is Match_yyyymmddhhmm.icc. Change it as required.
  10. Select Exit.
    The color matching process is complete, and the profile is saved. If you saved the golden sample data, load it next time you need to match colors and create a profile based on the same golden sample.
