The printer is instructed, through the print driver or raster image processor (RIP) to always print the static document when sending any page out to the printer driver or RIP. In one methodology, a static document is loaded into printer memory. There are three main operational methodologies for variable data printing. While the static elements appear exactly the same on each piece, the variable fields are filled in with text or images as dictated by a set of application and style rules and the information contained in the database. All variable data printing begins with a basic design that defines static elements and variable fields for the pieces to be printed. Finally there is full variability printing, where the text and images can be altered for each individual address.
More complicated variable data printing uses 'versioning', where there may be differing amounts of customization for different markets, with text and images changing for groups of addresses based upon which segment of the market is being addressed. The most basic level involves changing the salutation or name on each copy much like mail merge. There are several levels of variable printing. Instead of producing 10,000 copies of a single document, delivering a single message to 10,000 customers, variable data printing could print 10,000 unique documents with customized messages for each customer. Variable data printing enables the mass customization of documents via digital print technology, as opposed to the ' mass-production' of a single document using offset lithography. VDP is a direct outgrowth of digital printing, which harnesses computer databases and digital print devices and highly effective software to create high-quality, full color documents, with a look and feel comparable to conventional offset printing.
