When printing industry is still difficult to deal with from a traditional film-based printing environment directly to the printer to the digital workflow to fight the changes in time, another revolution is in the same background prompt access to the next opportunity. Adobe Introduces Acrobat application and its Portable Document Format PDF, pre-press system has attracted major manufacturers and software developers attention. The development of their co-operation to open PDF-based printing architecture, in order to capture the printing industry.
The early 80s, a new software company, Adobe System Inc. to develop a vector-based printing architecture. It allows personal computer users to start the PostScript laser printers and image Imagesetter, the output contains the text, graphics and images of the complexity of the page. This class completely changed the page description language of the digital printing industry.
Adobe's PostScript technology can be a copy of any size, density and style of fonts, and smoothing them with the edge of the object, for transfer of images and the complexity of the printing art together, and the little dots appear in the wrong place. Before the end of the 80's, Apple Computer, AlDus companies and Leno Tai Adobe-based company started selling a revolutionary new hardware and software code.
PostScript programming language into the 90's to continue to develop at the same time, there are some unpleasant obstacles. In the development of "new standards for the printing industry" in the wind and rain, all pre-press publishing company for many standard PostScript format, the original, creating a platform on very intimate terms, dozens of format, thousands of new fonts, new media The new delivery system and the new output device chaos. As a result, the PostScript language, there are many "dialects", and explain each document dialects vary. PostScript into a matter of fact all the standard pre-press operation, but increasing the output in the document need to be more stable and predictive.
Finally, Adobe announced in 1996 the Portable Document Format PDF. Have the same as in the past, PDF is a vector-based file formats, but PDF is the explanation of the process of goal-oriented in accordance with the internal standard rather than a specific shape configuration of the outer interpreter. Its success, based on the fact that the interpretation of the document generation process rather than a raster image processing.
A result, the interpretation is always the same regardless of the output PDF file using a PostScript RIP what dialect. PDF is also almost universally compatible with any computer platform.
