PDF/X

An ISO-standardized subset of the PDF format designed specifically for print production. Where a standard PDF may contain elements that display correctly on screen but produce unpredictable results on press (unresolved transparency, missing fonts, ambiguous color definitions), a PDF/X file is structured to eliminate those variables. Fonts are embedded, color profiles are defined, and the file is self-contained and unambiguous for the receiving print system.

CE.SDK supports PDF/X output through the Print Ready PDF plugin. The plugin takes CE.SDK’s standard RGB PDF export and converts it into a PDF/X-4 compliant file, performing color space conversion to CMYK, embedding an ICC color profile, and keeping transparency live and vector text intact. This process runs entirely client-side in the browser or server-side in Node.js, with no backend infrastructure required.

CE.SDK’s engine exports a standard RGB PDF. The Print Ready PDF plugin then converts it to PDF/X-4, applying a color profile selected to match the print destination. The conversion performs color space conversion to CMYK, embeds the ICC profile, and keeps transparency live.

Available Color Profiles

fogra39

European offset printing. Maps to ISO Coated v2 (ECI), based on the FOGRA39 printing condition.

gracol

US commercial printing. Maps to GRACoL 2013.

srgb

Digital distribution. Keeps the file in RGB for digital delivery channels that do not require CMYK conversion.

custom

Printer-specific ICC profile. Accepts a custom profile uploaded by the integrating team for specialized press configurations.

Commercial print handoff

Design and print platforms that pass files directly to print service providers need PDF/X as a standard delivery format. The Print Ready PDF plugin enables CE.SDK integrations to produce compliant files without a separate desktop application or post-processing step.

Web-to-print workflows

Web-to-print tools where users design online and order physical products need the file sent to print to describe its colors unambiguously. PDF/X-4 with an embedded ICC profile tells the press exactly which print condition the colors were prepared for.

Batch print production

The plugin works in Node.js, making it suitable for server-side, automated batch processing. A pipeline can generate PDF/X-4 files from CE.SDK scenes at scale (for variable data printing, personalized print products, or mass marketing material production) without manual export steps.

Packaging and labels

Packaging production workflows require print-accurate files with resolved colors and embedded profiles. PDF/X-4 output from CE.SDK satisfies this requirement for teams building packaging design tools on the SDK.

PDF/X output requires the Print Ready PDF plugin. CE.SDK’s own PDF export writes RGB by default, and on the web and in Node.js it can write CMYK colors as CMYK, but a full CMYK workflow with an embedded ICC profile and PDF/X compliance needs the plugin. Product teams building print workflows should plan for it as part of the integration.
