About BMP to PS Conversion
PostScript (PS) is Adobe's page description language for controlling printers, imagesetters, and professional print equipment. Converting BMP to PostScript wraps the uncompressed bitmap data in a PS program that describes the image as printer commands. The output can be sent directly to PostScript-compatible printers or processed by RIP (Raster Image Processor) systems.
BMP's uncompressed pixel data provides the cleanest possible source for PostScript conversion — no decompression artifacts, no quality ambiguity. The PostScript program faithfully encodes every pixel from the BMP source, producing output that is as accurate as the original when interpreted by a PostScript device.
Why Convert BMP to PS?
Commercial printing equipment using PostScript RIP systems may require PS input. Legacy prepress workflows, particularly those using older Harlequin or CPSI systems, expect PostScript files. When BMP images need to be fed into such systems, converting to PS provides the accepted format.
LaTeX document preparation using the traditional dvips pipeline requires PostScript graphics. When BMP images from Windows-based tools need to be included in TeX documents, PS (or EPS) conversion is the required intermediary step.
Common Use Cases
- Send BMP images to PostScript-compatible commercial printers and RIP systems
- Prepare BMP graphics for LaTeX documents compiled through dvips
- Create PostScript files from BMP for legacy prepress and typesetting workflows
- Generate printer-ready files from BMP for industrial label printing systems
- Convert BMP images for inclusion in PostScript-based page layout systems
How It Works
Ghostscript encodes the BMP's raw 24-bit pixel data as a PostScript Level 2 program. The pixels are encoded using ASCII85, wrapped in the PostScript image operator. DSC comments provide %%BoundingBox, %%Pages, and other structural metadata. Color data uses the RGB model. The output is a text-based program that can be viewed in any text editor. BMP does not carry transparency, so no alpha handling is needed.
Quality & Performance
The PostScript output contains a lossless representation of the BMP's pixel data (via ASCII encoding). No lossy compression is applied. BMP's uncompressed source provides the cleanest input — no pre-existing artifacts to propagate. Final print quality depends on the output device resolution relative to the image DPI.

Tips for Best Results
- 1BMP's uncompressed data provides the cleanest possible source for PostScript generation
- 2For LaTeX inclusion, rename .ps to .eps and verify the BoundingBox is correct
- 3Use ps2pdf to convert the PostScript to PDF for modern distribution
- 4PostScript files are text programs — you can inspect and edit coordinates in a text editor
- 5Consider converting BMP to PNG first to reduce intermediate file sizes before PS conversion
