Acrobat Distiller is a software application and a critical component of Adobe Acrobat that converts PostScript files (.ps) into Portable Document Format (PDF) files. Distiller acts as a bridge, enabling seamless conversion of the complex graphics and textual data found in PostScript files into the widely adopted and platform-independent PDF format.
Functionality
Core Conversion Process
Acrobat Distiller reads a PostScript file, interprets the data, and generates a PDF file with equivalent content. This process involves:
- Parsing PostScript Code: Distiller interprets the PostScript programming language, which contains descriptions of page layouts, fonts, and vector graphics.
- Rendering Graphics and Text: It translates the parsed code into the visual and textual content displayed in the final PDF.
- Embedding Fonts: Distiller can embed fonts used in the original PostScript file to ensure the PDF displays correctly on any machine.
- Compression: It offers options for compressing text and image data to reduce the file size of the resulting PDF.
Advanced Features
- Customization: Users can customize the conversion settings, such as choosing the level of image compression, and font embedding options.
- Security: Distiller provides the ability to encrypt and password-protect the PDFs.
- Job Options: Users can select from predefined settings or create their own, optimizing the conversion for specific purposes such as print production, web publishing, or high-quality viewing.
Historical Context
Birth and Evolution
Introduced in the early 1990s, Acrobat Distiller has evolved in tandem with the PDF format and Adobe’s suite of document management tools. The initial versions focused primarily on converting desktop publishing files into a robust, portable format for printing and sharing. Over time, as the PDF format gained widespread acceptance, Distiller’s functionality expanded to meet the demands of various industries, including publishing, legal, education, and more.
Applications
Publishing and Printing
- Prepress Workflow: Ensures that documents are accurately converted from design software to a print-ready format.
- Archival Quality: Maintains high fidelity and consistency in document reproduction, crucial for digital archives.
Document Management
- Standardization: PDF is a standardized format (ISO 32000), making Distiller essential for creating compliant documents.
- Compatibility: Ensures documents are viewable on any device with PDF support.
