Variable data printing (VDP) is digital printing that uses records in a database or data file to change selected content from one printed piece to the next. A shared design can stay the same while names, images, graphics, or codes vary for each record.
How variable data printing works
A VDP job connects a design to structured data and rules that determine what appears in each copy. Typically, it includes:

- A template: the layout and fixed design elements shared across the job.
- A data file or database: records containing information such as names, addresses, or other recipient-specific details.
- Field mappings and rules: instructions that connect data fields to locations in the design and determine when content changes.
- VDP software and a digital print device: the software prepares individualized pieces for printing.
For example, Esko WebCenter documentation describes uploading an artwork template and CSV file, then linking the file to the template. Roland DG describes a workflow using a template, a data file, and, optionally, image files. The exact setup depends on the software and production workflow.
What can vary from one printed piece to another?
The variable content can be as simple as a recipient’s name and address or can include several kinds of record-specific content. Depending on the design and workflow, it may include:

Fiery Help and Documentation describes a personalized address block in a mail merge as a simple form of VDP. More complex jobs can vary multiple elements or use rules to select content for each record.
Where VDP is used
Documented examples include personalized letters and brochures, direct mail and advertising, postcards, newsletters, employee ID cards, and sequentially numbered tickets. The common thread is that each piece is printed from a record, while shared design elements can remain consistent across the run.

How VDP differs from ordinary batch printing
In a conventional print run, copies generally reproduce the same content. VDP adds record-based changes within the job: the layout may remain constant, but designated content changes from piece to piece. A personalized address block is one straightforward example; changing images, graphics, or other objects according to each record is a broader use of the same approach.

Formats and compatibility depend on the production system
VDP is a digital-printing workflow, but support for particular file formats and job features is not universal. Canon PRISMAsync documentation, for example, names PPML and PDF/VT support for its VDP workflow; that is a product-specific example, not a promise that every printer or controller supports either format.

Before preparing a job, confirm that the authoring software, data structure, print controller, and press support the format and variable features you plan to use. Compatibility matters especially when a job includes linked images, complex rules, or more than basic text changes.
