InDesign File Packaging
Before you send your InDesign files in to print, you will need to gather all of its parts together by packaging the file. When you package a file, you create a folder that contains the InDesign document (or documents in a book file), all necessary fonts, linked graphics, text files, and a customized report.
To package your InDesign file, open your document and click File > Package... In the dialogue box that opens make sure there are no missing fonts or images and click the "Package..." button. A window will open that asks for contact information; this will create a .txt file that the Prepress department will use to contact you if there are any issues. Click "Continue." Give your packaged folder a descriptive name and choose a location to save it. A folder will then be created with everything the printer will need.
InDesign performs an up-to-date preflight check that will help you ensure all fonts and images are linked or embedded, and that the colors are correct. The Package Inventory dialog box indicates any detected problem areas and has several menu options that can help you locate issues in your InDesign document you may not have noticed.
Information about the document is displayed here, including any errors that are found (such as images that are not in CMYK, missing fonts or images).
This lists all the fonts that are used in the document. It tells you the name of the font, what type it is (postscript, truetype, etc), and if it is present or missing. If there are errors select the specific font and then click "Find Font..." to see available options. You can change the font in the "Find Font" window, if you wish. Each instance of the original font will be changed to the new font you specify in the "Replace With" section of the "Find Font" dialogue box.
Links and Images
This section will tell you if there is anything wrong with your images. Make sure there are no missing images (if there are, select the image and click "Relink" to find it). If you have images that were created in the RGB color space, a warning will appear here. You can edit your images in Photoshop or Illustrator and convert them to CMYK if you wish, or you can let our Prepress department do this.
Colors and Inks
Process (CMYK) and spot colors are listed in this view. You should see Process Cyan, Process Magenta, Process Yellow, and Process Black. If there are spot colors listed you may want to go back to your document and convert those colors to process, unless your printer knows you intend to use spot colors. You can change spot colors in your InDesign document by canceling out of the Package window and right clicking on the spot color in the "Swatches" palette. Select "Swatch Options," then change the Color Type to "Process." Go back to the Package window by clicking File > Package.
Print Settings and External Plug-ins
These are a list of settings and plug-ins that are used in the document. They cannot be changed in the Package dialogue box.
