Variable Data Printing

A print production workflow in which a single design template is used to generate many physical print outputs, each containing unique personalized content drawn from a data source. VDP is distinct from general creative automation: where creative automation refers broadly to the programmatic creation or editing of designs across any output format, variable data printing refers specifically to using data to create variations of a design template whose outputs are then sent to a downstream printing workflow that produces physical prints.

The term has been used in the print industry since the 1980s. Common everyday encounters with VDP output include addressed direct mail, personalized event tickets, membership cards, and utility bills, all produced from a shared template with individual data fields substituted per recipient.

Postbuddy is a Denmark-based direct mail platform that helps e-commerce brands reconnect with dormant customers through automated postcard campaigns. Users design postcards within the embedded CE.SDK editor, insert variable fields for recipient names, coupon codes, and other per-recipient data, then upload a CSV to auto-generate thousands of personalized, print-ready cards in a single run, with bleed configuration and print specifications handled natively.

The platform also supports A/B testing across two postcard designs within the same campaign, applying the data-driven experimentation approach marketers use for email to physical mail. With design, personalization, and print workflow unified in one product, Postbuddy eliminated friction for non-technical users and avoided building a custom editor entirely, freeing the team to focus on growth. The company has since expanded from Denmark into Sweden and Norway, with further European markets planned.

CE.SDK supports VDP through its Variables API and template system. A template author (using the Creator role) designs a layout and marks text elements as variable, using the {{variableName}} token syntax, to define the fields that will be populated per record. Image placeholder blocks can also be configured to receive dynamic assets per data point.

The template is then connected to a data source, and CE.SDK’s headless engine generates one rendered output per record, with the engine automatically adjusting font sizes and spacing to ensure each variation is production-ready.

Export output for VDP workflows is typically PDF, with print-accurate options available via the Print Ready PDF plugin: PDF/X-3, CMYK, and embedded ICC profiles.

Direct mail personalization

Postcards, flyers, and mailers are produced from a single template with recipient name, address, and personalized offer fields substituted from a CRM or marketing database. Each physical piece is individually addressed and customized.

Event ticketing and credentials

Tickets, badges, and certificates are generated from a shared design with per-attendee or per-recipient data: name, seat, QR code, or accreditation details.

Loyalty and membership cards

Cards are produced in batches with individual member names, IDs, and tier-specific content, generated from a single template against a member database.

Product labels and packaging

Packaging workflows that require per-SKU or per-batch label variations (barcodes, batch numbers, localized content) use VDP to generate each label variant from a shared layout.

In CE.SDK, the same template and Variables API can support both. The distinction is in how the output is handled after export, not in how the template is built or how the engine is invoked.
