388 Chapter 9 – VI Workflow
VI Overview
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 self-
contained 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 CXP6000 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.
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.
For more information about cached VI elements, see Managing VI Elements on
page 398.
