About DPX to PS Conversion
DPX (Digital Picture Exchange) is the SMPTE 268M digital cinema standard, storing film scan data at 10-bit or 16-bit depth with logarithmic color encoding for VFX, color grading, and digital intermediate workflows. PS (PostScript) is Adobe's page description language for professional printing systems, imagesetters, and prepress workflows.
Converting DPX to PostScript prepares cinema-grade frame images for high-end printing systems. This conversion is relevant for producing exhibition prints, poster proofs, and physical production documents from film scan data. The PostScript output carries the color-corrected frame image in a format that professional printing equipment can process directly through RIP (Raster Image Processor) hardware.
Why Convert DPX to PS?
Film festival exhibitions, gallery shows, and museum displays of cinema art require physical prints from digital film data. DPX is the source format for these frames, but printing systems accept PostScript (or PDF, which evolved from PostScript). Converting DPX to PS enables direct output to professional large-format printers, digital presses, and fine art printing systems.
Production offices occasionally need high-quality physical prints for set decoration reference, continuity boards, and production design inspiration walls. Converting key DPX frames to PostScript produces print-ready files that any print service bureau can process without specialized cinema software.
Common Use Cases
- Produce exhibition-quality prints from DPX film scan data for festival galleries and museum shows
- Create poster proofs from DPX graded frames for approval before full production runs
- Print continuity reference images from DPX dailies for on-set production boards
- Generate PostScript output from DPX for processing through high-end RIP devices
- Prepare DPX frames for fine art giclée printing on professional wide-format inkjet systems
How It Works
The DPX data is decoded with log-to-linear color space conversion, applying a Cineon-to-sRGB or Cineon-to-print-profile LUT. The converted image is wrapped in a PostScript Level 2 or Level 3 program using image operators. Pixel data is encoded as ASCII85 streams. Page dimensions are calculated based on image resolution and desired print size (default 300 DPI). For CMYK printing, a separate ICC profile-based color conversion step is recommended before PostScript generation.
Quality & Performance
The print quality depends on three factors: (1) the accuracy of the log-to-linear LUT, (2) the source DPX resolution relative to the print size, and (3) the CMYK conversion accuracy if applicable. A 2K DPX frame at 300 DPI produces a ~7x5 inch print area — suitable for reference prints. A 4K frame doubles this to ~14x10 inches. The PostScript output preserves the full converted resolution without additional lossy compression.

Tips for Best Results
- 1Use a proper film stock or show LUT for color-accurate prints rather than the generic Cineon transform
- 2Consider PDF instead of PostScript for modern printing — PDF is more widely accepted and more efficient
- 3For exhibition prints, work with your print shop to determine the correct ICC profile for CMYK conversion
- 44K DPX provides sufficient resolution for large-format prints up to ~28x20 inches at 150 DPI
- 5Test a single frame before batch converting to verify print quality and color accuracy
DPX to PostScript conversion bridges digital cinema data and professional printing, enabling exhibition prints, poster production, and physical documentation from film scan source material.
