About CBR to PS Conversion
CBR (Comic Book RAR) is the standard comic book archive format, wrapping sequential page images in RAR compression for digital comic reader applications. PS (PostScript) is Adobe's page description language, used in professional printing and prepress workflows. Converting CBR to PS transforms comic book page images into a PostScript document suitable for high-end printing systems and RIP (Raster Image Processor) devices.
PostScript was the foundation of desktop publishing and remains the native language of many professional printing systems. Converting CBR to PS enables comic pages to be sent directly to PostScript-compatible printers, imagesetters, and prepress workflows without intermediate format conversions. This is relevant for independent comic publishers and print shops producing physical comic books from digital archives.
Why Convert CBR to PS?
Professional print production for physical comic books often requires PostScript input. Commercial printing presses, especially older prepress systems and imagesetters, accept PostScript files directly. Converting CBR to PS prepares digital comic archives for physical production runs, enabling independent publishers to produce printed copies from their digital libraries.
PostScript's precise page description capabilities allow fine control over page sizing, margins, registration marks, and color separation that image formats cannot express. A comic page in PostScript can carry trim marks, bleed specifications, and CMYK color data that direct a printing press to produce accurate physical reproductions. This level of control is essential for professional comic book printing.
Common Use Cases
- Prepare digital comic archives for physical printing on PostScript-compatible printing presses
- Send comic pages to prepress workflows that require PostScript input for plate-making
- Generate PostScript proofs of comic pages for print quality verification before full production runs
- Feed comic page images into RIP devices that convert PostScript to printer-ready output
- Produce print-ready files from CBR archives for independent comic publishing
How It Works
The conversion extracts page images from the RAR archive and wraps each in a PostScript program. Each page is described as an image operator within the PostScript language, with the pixel data encoded as ASCII85 or binary data streams. Page dimensions are calculated from image resolution to produce correctly sized PostScript pages (typically 6.625 x 10.25 inches for standard US comic format). The output conforms to PostScript Level 2 or 3 for broad printer compatibility. Color data is maintained in RGB; CMYK conversion requires a separate prepress step.
Quality & Performance
The source page images are embedded in the PostScript file at their original resolution without any lossy recompression. PostScript preserves the full pixel data of each page, making the output suitable for high-resolution printing. Print quality depends entirely on the resolution of the original scanned pages — 300 DPI or higher is recommended for professional comic printing. Lower-resolution scans (150 DPI) will produce acceptable but not professional-grade print output.

Tips for Best Results
- 1Verify that your printing system actually requires PostScript — most modern workflows accept PDF instead
- 2Use 300+ DPI source scans for professional-quality print output from PostScript files
- 3Convert to PDF instead of PS for broader compatibility with modern printing systems
- 4Expect very large file sizes — PostScript encodes image data less efficiently than binary formats
- 5Consult with your print shop about required specifications (page size, bleed, color space) before conversion
CBR to PS conversion bridges digital comic archives and professional print production. The PostScript output carries the page images in a format that printing systems can process directly, enabling physical comic book production from digital libraries.
