About MEF to PS Conversion
PostScript (PS) is Adobe's page description language, foundational to professional printing and publishing since 1984. Converting Mamiya MEF RAW files to PostScript embeds medium format photographs in a print-ready PostScript program suitable for high-end commercial printing, imagesetting, and prepress production pipelines.
The extraordinary resolution of Mamiya medium format sensors (22-80+ megapixels) makes these captures ideal for large-format PostScript output. The MEF data is demosaiced, color-corrected, and embedded in a PostScript page structure that can be sent directly to PostScript RIP systems for plate-making and commercial print production.
Why Convert MEF to PS?
High-end commercial print production still relies on PostScript-based workflows for plate-making and imagesetting. When Mamiya medium format photographs need to enter a traditional print production pipeline — for fashion magazines, art books, exhibition catalogs, or large-format advertising — PostScript provides direct compatibility with these professional systems.
Medium format cameras are used specifically because their high resolution supports large print sizes. PostScript is the native language of the systems that produce those large prints. Converting MEF to PS creates a direct path from medium format capture to print production without requiring intermediate format conversions at the print facility.
Common Use Cases
- Send Mamiya 645DF+ fashion photographs directly to PostScript-based prepress systems for magazine production
- Prepare Phase One medium format captures for PostScript RIP processing at commercial print facilities
- Include Mamiya studio photographs in PostScript-based art book and catalog production workflows
- Generate PostScript pages from medium format captures for large-format advertising print production
- Create PostScript proofing files from medium format commercial shoots for client approval
How It Works
The MEF file is decoded through LibRaw, producing a full-color demosaiced image from the medium format sensor. The RGB image data is encoded within a PostScript program using the image operator, with page dimensions set to match the image resolution at the specified DPI. For a 60 MP capture at 300 DPI, the PostScript page can be approximately 20x15 inches. Ghostscript handles the PostScript generation, producing output compatible with PostScript Level 2 and Level 3 interpreters.
Quality & Performance
The image quality in the PostScript file matches the demosaiced MEF output. PostScript supports both JPEG-encoded and uncompressed image data embedding. For commercial print production, CMYK color space conversion can be applied during the conversion. The full resolution of the medium format sensor is preserved, enabling large-format printing at professional quality.

Tips for Best Results
- 1Use PostScript only for print production systems that specifically require it — PDF is more practical for general use
- 2Set page dimensions and DPI to match your intended print output specifications
- 3Test PostScript output with Ghostscript before sending to expensive commercial print systems
- 4Medium format resolution fully supports large-format PostScript pages at 300 DPI
- 5Request the CMYK color profile from your print facility if color accuracy is critical
MEF to PS conversion connects Mamiya medium format photography with professional PostScript-based print production systems for high-end commercial publishing.
