In order for a PostScript print file to properly distill to PDF using Adobe tools, it should conform to basic DSC standards. Some DSC comments serve a second function, specifying a way to tell the document manager to do certain things, like inserting a font or other PostScript code (collectively called resources) into the file.
An overlapping term is printer control language, which includes Hewlett-Packard's Printer Command Language (PCL). PostScript is one of the most noted page description languages. The markup language adaptation of the PDL is the page description markup language.
Both documents produce the same result when printed. The difference between the PDF and PostScript is that the PDF lacks the general-purpose programming language framework of the PostScript language. A PDF document is a static data structure made for efficient access and embeds navigational information suitable for interactive viewing. [19]: 9
which specifies that the printer understands PostScript Level 2, is a color device, and so forth. The PPD can describe allowable paper sizes, memory configurations, the minimum font set for the printer, and even specify a tree-based user interface for printer-specific configuration.
Traditionally, to go from PostScript to PDF, a source PostScript file (that is, an executable program) is used as the basis for generating PostScript-like PDF code (see, e.g., Adobe Distiller). This is done by applying standard compiler techniques like loop unrolling , inlining and removing unused branches, resulting in code that is purely ...
A raster image processor (RIP) is a component used in a printing system which produces a raster image also known as a bitmap. [1] [2] Such a bitmap is used by a later stage of the printing system to produce the printed output. The input may be a page description in a high-level page description language such as PostScript, PDF, or XPS.
The Portable document format (PDF) also includes a spot color called All, with the same restrictions, starting with PDF 1.2. Note that a PDF spot color must also include a "tint transform" which translates spot values into a different color space for viewing on screen, or printing to printers without spot color support. There is no special rule ...
Ghostscript is a suite of software based on an interpreter for Adobe Systems' PostScript and Portable Document Format (PDF) page description languages.Its main purposes are the rasterization or rendering of such page description language [4] files, for the display or printing of document pages, and the conversion between PostScript and PDF files.
