Before saving a document as a PDF file, you can preflight your document to find potential problems. Preflighting checks and displays a summary of errors, possible problems, and suggestions for resolving issues. By default, many PDF issues are checked during a preflight, but you can disable the issues that you do not want to check.
You can save settings by clicking the Add preflight settings button and typing a name in the Save preflight style as box.
The features documented in the Help are available in the full version of CorelDRAW Graphics Suite 2021. Some features may not be available in this version of the product.
