About ICO to PS Conversion
ICO (Windows Icon) stores multi-resolution icon images, while PS (PostScript) is Adobe's page description language for professional printing. Converting ICO to PS embeds the icon image within a PostScript document, creating a print-ready file for legacy PostScript printers and prepress workflows. This is a specialized conversion for situations where icon images need to be printed through PostScript-based systems.
PostScript wraps the rasterized icon image in executable PostScript code that describes the page layout, image placement, and rendering instructions for PostScript interpreters and printers.
Why Convert ICO to PS?
PostScript printers and RIP systems in legacy print environments may require PS input for all printed content, including small icon images for documentation, packaging, or signage. Converting ICO to PS ensures icon images can be processed by these systems without manual intervention from a prepress operator.
PS format is also useful for automated PostScript workflows that assemble multiple elements into print-ready pages. Converting ICO icons to individual PS files allows them to be included programmatically in larger PostScript documents.
Common Use Cases
- Print icon images on PostScript printers for documentation and reference sheets
- Include ICO icon images in PostScript-based automated print workflows
- Create PostScript proofs of icon designs for prepress review
- Generate PS files from ICO for legacy printing systems that require PostScript input
- Package icon images as PostScript for inclusion in PS-based page assembly
How It Works
The largest resolution image from the ICO container is extracted, decoded to a pixel buffer, and embedded within a PostScript program using Level 2 image operators. The image data is encoded as ASCII85 or binary hexadecimal within the PS file. Page dimensions are derived from the icon's pixel dimensions, and the image is centered on the page. Ghostscript-compatible DSC comments provide document structure information. ImageMagick handles the ICO decoding and PostScript generation.
Quality & Performance
The icon image is embedded at its native resolution. PostScript stores the pixel data without additional compression artifacts. The visual quality is identical to the extracted ICO image. The small dimensions of icon images (up to 256x256) mean the PS file is compact even with ASCII85 encoding.

Tips for Best Results
- 1Use PDF instead of PS for modern printing -- PS is only necessary for legacy PostScript systems
- 2The icon image will be small on the PS page due to icon dimensions being inherently limited
- 3Test PostScript output with Ghostscript before sending to production printers
- 4Icon transparency is flattened against a white background in PostScript output
- 5For icon reference sheets, convert multiple ICO files to PS and combine them with a PS page compositor
