FPO images are commonly used when you’ve been supplied actual photographic prints or another type of artwork to be scanned or photographed for inclusion. With modern publishing software and digital photography, FPO is a term that is mainly historical in nature; it’s rarely used in everyday practice anymore.
Uses for FPO
Before the days of fast processors, FPO images were used during the design stages of a document to speed up the process of working with the files during various drafts of a document. Processors are much faster now than they used to be, so delays are minimal, even with high-resolution images—one reason FPO isn’t in use much. FPO was usually stamped on an image to avoid accidentally printing a low-resolution image or an image the publisher did not own. Images not to be printed are usually labeled with a large FPO across each one, so there is no confusion about whether they are to be used. In newspaper production, newsrooms that use paper dummy sheets—grids with columns along the top and column inches along the sides—block images or illustrations FPO by creating either a black box or a box with an X through it. These dummy sheets help editors estimate the number of column inches necessary for a given newspaper or magazine page.
FPO and Templates
Although they may not be labeled as such, some templates contain images that can be considered FPO. They show you where to place your images for that particular layout. The text equivalent of FPO images is placeholder text (sometimes referred to as lorem ipsum, since it’s often pseudo-Latin). Occasionally, FPO is used in web design when an image labeled FPO allows coders to finish building a website without waiting for the final images for the site. It allows the designers to account for color palettes and image sizes until the permanent images become available. In fact, many web browsers including Google Chrome allow for optimized page rendering, wherein FPO placeholders fill the page, and the text surrounds it. The images only pop into the placeholders after they’ve been fully downloaded.
Modern Analogues
Although FPO placement isn’t as common with a fully digital production cycle, common publishing platforms retain vestiges of the practice. For example, Adobe InDesign—a leading design application for print projects such as books and newspapers, places images at medium resolution by default. To see the high-resolution image, you must manually override the image or tweak the application’s settings. Open-source publishing tools, like Scribus, behave similarly. They support placeholder images during document editing to reduce processor overhead and streamline the text-review process.
