PSからPDFへの変換について
PostScript (PS) is the original Adobe page description language that defined professional printing from the mid-1980s through the 2000s. PDF (Portable Document Format) is PostScript's successor, also created by Adobe, which extracts the best of PostScript's rendering model while adding interactive features, document structure, accessibility, compression, and universal viewing capability. PDF is now an ISO standard (ISO 32000) and the world's most used document format.
PS-to-PDF is the natural evolution path: converting from the older print-focused format to its modern, universally viewable successor. This conversion preserves the visual fidelity of PostScript output while adding PDF's advantages: smaller file sizes, built-in fonts, searchable text, bookmarks, and native viewing in every web browser and operating system.
PSをPDFに変換する理由
PostScript files require a PostScript interpreter (Ghostscript) or a PostScript-capable printer to view or output. PDF files open instantly in every web browser, operating system, and mobile device without any additional software. This alone makes PS-to-PDF conversion essential for any PostScript content that needs to be viewed, shared, or archived.
PDF provides significant technical advantages over PostScript: ZIP/Flate compression reduces file sizes by 50-90%, font subsetting embeds only the glyphs actually used, text is searchable and selectable, bookmarks provide navigation, and PDF/A archival format ensures long-term preservation. The PDF format also supports encryption, digital signatures, and form fields that PostScript cannot provide. For organizations with PostScript archives, converting to PDF is the standard digital preservation strategy.
主な活用例
- Convert PostScript print archives to PDF for long-term digital preservation in document management systems
- Transform PostScript prepress files into viewable PDF for client review and approval workflows
- Migrate legacy PostScript document collections to PDF for web-based document sharing and collaboration
- Convert PostScript output from legacy DTP applications into PDF for modern distribution channels
- Transform PostScript technical manuals and specifications into searchable, bookmarked PDF documents
仕組み
A PostScript interpreter performs the PS-to-PDF conversion, which interprets the PostScript program and outputs a structured PDF document. Unlike rasterization, this conversion preserves vector graphics, text as selectable characters, and embedded fonts — producing a PDF that maintains the mathematical precision of the original PostScript. Ghostscript applies Flate (ZIP) compression to reduce file size, subsets embedded fonts to include only used glyphs, and generates a proper PDF cross-reference table for efficient random access. The output conforms to PDF 1.4 or higher, with options for PDF/A (archival), PDF/X (prepress), and PDF/E (engineering) compliance. PostScript Level 1, 2, and 3 features are all supported.
品質とパフォーマンス
PS-to-PDF conversion is essentially lossless for the visual content. Vector graphics remain as vectors, text remains as selectable characters, and embedded fonts are preserved. The PDF output renders identically to the PostScript original when viewed in a PDF reader. File size typically decreases significantly (50-90%) due to PDF's superior compression. The only quality consideration is for PostScript files that rely on Level 3 features not fully supported by the target PDF version, though this is rare. Color fidelity is preserved, including CMYK color spaces for prepress workflows.

最良の結果を得るためのヒント
- 1Use this conversion for all PostScript files in your archive — PDF is superior in every way for viewing, sharing, and preservation
- 2Request PDF/A output for long-term archival to ensure the document remains readable for decades
- 3Verify that all PostScript fonts are embedded in the PDF to ensure consistent rendering on any device
- 4For prepress workflows, request PDF/X output to maintain CMYK color fidelity and print specifications
- 5Check bookmarks and navigation in the PDF — Ghostscript can generate bookmarks from PostScript's DSC comments
