The job processing may sometimes fail because a spot color from your input PDF could not be found. The job will then be listed under Jobs > Errors with the status Spot color [name] wasn't found. You have two options to fix such a channel mapping error:
- Persistent channel mapping rules for a conversion: You can add a channel mapping rule to your resources and then restart the job (see "Channel Mapping Rules").
- Temporary channel mapping for specific jobs: You can use the channel mapping feature in the job list to map the spot color for a specific job without altering your resources.
- Under Jobs > Errors, right-click on the relevant job and choose Channel Mapping.... Alternatively you can select the job and click the Channel Mapping button from the ribbon.
The job-based Channel Mapping dialog will open.
- Under Input Channel, you can see the names of all unrecognized input channels. On the right, there is also a warning message shown for each unrecognized channel.
- Click into an input channel's Rule column and select the desired action from the dropdown menu.
- Remove will remove objects with this input channel name from the PDF.
- Keep unchanged will keep objects with this input channel name unchanged.
- Map to... allows you to map objects with this input channel name to an alias spot color from your library. The spot color will then be processed as defined in the conversion.
- If you selected Map to... previously, click into the channel's Alias Spot Color column and select the desired alias spot color from the dropdown menu. You can type to filter the list and find the desired spot color quickly.
- Repeat steps 3 and 4 for all unrecognized channels, until all warning messages disappear.
- Click on Process job to restart the job with your changes applied.
