About CBZ to PS Conversion
CBZ (Comic Book ZIP) is the open-standard comic archive format using ZIP compression, widely supported by Calibre and open-source comic management ecosystems. PS (PostScript) is Adobe's page description language, designed for professional printing and prepress systems. Converting CBZ to PS transforms comic pages into PostScript programs that professional printing systems can process directly.
PostScript encodes each page as a series of graphics commands rather than raw pixel data, making it the native input format for imagesetters, platemaking systems, and high-end digital presses. This conversion enables independent comic publishers and print-on-demand services to produce physical comic books from their open-format digital archives.
Why Convert CBZ to PS?
Print shops and commercial printing facilities that produce physical comic books may require PostScript input for their production pipeline. Older prepress systems, particularly those used by specialist comic printers, accept PostScript files and process them through RIP (Raster Image Processor) hardware to produce printing plates. Converting CBZ to PS integrates open-format digital comics into these established print workflows.
PostScript also serves as an intermediate format for PDF generation in some workflows. Tools like Ghostscript convert PostScript to PDF with precise control over compression, resolution, and color management. Some publishers prefer this two-step approach (CBZ to PS to PDF) because it allows fine-tuning at the PostScript level before producing the final PDF.
Common Use Cases
- Produce PostScript files from CBZ archives for submission to commercial comic book printers
- Feed CBZ comic pages into RIP systems that require PostScript for plate-ready output
- Create PostScript proofs from CBZ archives for print quality review before production
- Use PostScript as an intermediate format in CBZ-to-PDF pipelines requiring fine-tuned control
- Submit open-format CBZ comics to prepress workflows at printing facilities accepting only PS input
How It Works
The ZIP container is decompressed and page images are extracted in reading order. Each page is wrapped in a PostScript program that describes the image using Level 2 or Level 3 PostScript image operators. Pixel data is encoded as ASCII85 streams for text-safe transport or binary streams for efficiency. Page dimensions are calculated from image resolution to produce correctly sized PostScript pages. The output is compatible with Ghostscript, Adobe Distiller, and hardware PostScript RIP devices.
Quality & Performance
Page images are embedded in the PostScript program at their original resolution. No resampling, compression, or color conversion is applied during the embedding. The PostScript output reproduces each page at print-quality fidelity when processed by a RIP device. Final print quality depends on the resolution of the source images — 300 DPI or higher is recommended for professional comic printing.

Tips for Best Results
- 1Verify with your print shop that PostScript is actually required — PDF is more commonly accepted today
- 2Use 300+ DPI source pages for professional print quality from PostScript output
- 3Ghostscript can convert the PostScript to a print-ready PDF with fine-tuned compression settings
- 4CBZ's open format ensures reliable, repeatable extraction for production workflows
- 5Test the PostScript output on a software RIP (like Ghostscript) before sending to a hardware RIP
CBZ to PS conversion bridges open-format comic archives and professional print production, producing PostScript files ready for commercial printing systems and prepress workflows.
