Discuss the use of the Preflight panel to prepare files for printing.

What will be an ideal response?

When you complete a document, it is very important to find and correct any errors in the document to ensure that it prints correctly. The Preflight feature is an InDesign utility that you can use to check an open document for errors such as missing fonts, missing or modified links, and overset text. Any errors that are found are listed in the Preflight panel; you can use this list to fix any problems by substituting fonts, fixing overset text issues, and/or updating missing and modified files. A green circle on the left side of the status bar indicates that there are no preflight errors in a document; when the circle is red, there are errors. You can create customized preflight profiles in which you indicate what you would like the Preflight panel to flag as errors to be fixed. For example, you may want InDesign to flag font sizes smaller than 12 points as an error because your document cannot contain any font sizes smaller than 12 points.
