376 VI Overview Chapter 9 - VI Workflow Variable information (VI) jobs are jobs in which the printed materials are individualized for specific recipients or purposes. These materials can include bills, targeted advertising, and direct mailings. VI jobs are composed of booklets, which are personalized copies of a document. A booklet can consist of one or several pages, but the entire document is targeted at a specific individual or address. For example, a booklet can be either a single-page gas bill or a multipage personalized document. Each page in the booklet is constructed as a collection of individually RIPed elements that may differ from booklet to booklet, including text, graphics, pictures and page backgrounds. These elements are selfcontained graphical entities that may be line art, text, RIPed images, or a combination of these. There are two types of elements in VI jobs: • Unique elements are used only once for a specific individual or purpose. An individual's name is an example of a unique element. • Reusable VI elements can be used more than once in different pages, booklets, or jobs. A company logo is an example of a reusable element. On the Spire CXP8000 color server, each element, text, graphic, picture, or page background is RIPed only once, even if the element is used once, several times, or in every page of the VI job. If it is used more than once, then it is cached, or stored, for further use. You can manage these elements in the Resource Center under the Cached VI Elements area. Each set of elements associated with a particular job is assigned a unique name. Inline variable elements that are used only once, usually text, are not cached. For more information about cached VI elements, see Managing VI Elements on page 385. Pages are assembled from the pre-RIPed reusable elements and the RIPed unique elements just before printing. Then the job is printed in the same way as all other jobs in an RTP format.
