The print quality of the printed output depends on the media used. When you add media to the media catalog, you can define attributes that influence the print behavior of the print system for these media types. (Learn about the media-based workflow)
When you notice that output media in the output tray is curled, perform a correction procedure to prevent curled sheets. (Correct curled output media)
If you notice that the media quality of the printed output is not according to your expectations, perform a correction procedure to adjust the media registration. (Adjust the media registration)
The correction procedures change the media attributes in the media catalog, so that the adjustments are applied to all jobs that use the same media.
