Using Preflight

Adobe InDesign provides integrated controls for checking the availability of all files necessary for imaging a document. You can use these controls to preflight your file, confirming that all graphics and fonts used in the file are available for printing. You can also check the colors used in the document, including fonts and colors used in placed graphics.

Choose File > Preflight. The Preflight dialog box opens.

In the Preflight dialog box, review the summary panel that appears. InDesign alerts you to several potential concerns, noted by the yellow triangle adjacent to the information. These include:

  • One image is missing.

  • One image uses RGB colors.

  • Duplicate spot-colors may exist.

The summary section of the Preflight dialog box provides a fast overview of possible concerns in a document. For more detailed information you can click each of the six options along the left side of the dialog box.

Click the Fonts option to see a detailed list of fonts used in the document. You can learn about the fonts used in this job and whether they are OpenType, PostScript, or TrueType. You can also obtain additional information about fonts used in this job, including:

  • Whether a font is available for printing, missing, or incomplete.

  • If a font is protected from embedding in a PDF by the font manufacturer.

  • The first page on which the font is used.

  • The location of the font file being used.

While continuing to examine the Fonts, click to select the Show Problems Only checkbox at the bottom of the Preflight dialog box. Notice how no fonts are listed, as all fonts are available for printing and there are no problems with them.

Click the Links and Images option along the left side of the Preflight dialog box.

Notice that information regarding all images used in the file is displayed. We want only to view possible problems.

Click to select Show Problems Only. Notice that three images are displayed as possible problems. One file, slapshot.tif, uses RGB colors. Because the document will be printed using CMYK colors, this could be a problem. The other image, blammo_logo.ai is missing and needs to be located before the document can be printed.

You will replace the Blammo logo with a revised version that includes a trademark symbol along with the logo. You will address the RGB image in the printing process.

Click the Repair All button. Browse to the Links folder inside the Lesson_12 folder. This folder is located inside the Lessons folder within the InDesignCIB folder on your hard disk. Double-click the blammo_logo_revised.ai. The new file is now linked, in place of the original file.

Click to select the blammo_logo_revised.ai then click Update.

Because the file name is different, InDesign did not automatically update the image. If the selected file had not been modified since it was originally placed, InDesign would not have required you to update the link.


The Repair All allows you to repair missing or modified links. It does not allow you to change the color space defined in a placed graphic. You can do this by opening the linked image in Photoshop and changing its color space or you can have InDesign convert the colors for printing.

Click the Colors and Inks option.

Notice that the four subtractive primary colors are listed: Cyan, Magenta, Yellow, and Black along with three variations of Pantone 2582. The C is for coated, M is for matte, and U is for uncoated. Because we will not want all three of these colors to print independently, we will want to correct this at the time we print this document.
