Description

In the process of Publishing, storage of the image files not be divided into a single file or page, but also as a separate file preserved. Including all image data. When the files into page software applications and print, you print is a synthetic PostScript files (the color of all information contained in a file or page). The file through the RIP separation. Usually in this way, can guarantee the workflow simpler and more reliable can reflect “what you see is what you get”. To you on the monitor of the documents and synthesis print out

If you want to in typesetting in the course of the color image formats, you need in PhotoShop or create PostScript files with both the color image synthesis of synthesis of the software function image. In addition, some pre-determined color separation workflow system have deal with the problem of special provisions. So if the file format is the color image file, then you will have to do a lot of work to convert to typesetting workflow. Another important question is the PDF files output sex problem. Contain “general aviation” publishing market files. In many cases, the creation of PDF generated a can in different RIP and output equipment general format. Obviously, PDF will give publishing process from design to production page in the output a lot of benefits. Acrobat PDF file continue to improve and develop to print and online bring great convenience. In addition, provided by a third party of Acrobat plug-ins and the application will further support and expand its functions, making PDF workflow get more extensive application.

As a file transfer format, PDF can provide content in the place where the document to create and printing department or other related departments. Of course, these file format characteristics of itself far cannot satisfy the requirement of receiver to file. Publishing, printing department accept the applications in file still exists many always so remains to be updated version of the file format to appear. At present, PDF is receiving more and more attention. It plays a very important role in today’s image processing industry. Although the application of PDF still has many obstacles, but its appearance with customers have changed our communicated way.

Now almost all of the output devices are equipped with Adobe PostScript3 RIP or other attachments. They support PDF files as input file format, in process of different types. It will affect many such as trap, alignment of the task before printing. At present, the local PDF files of the trap and alignment confined to a new before printing workflow and some third party applications. However, as the trap alignment software new version of the release, the situation can be improved.

PDF can be able to ensure that the digital advertising in any place in the world for transmission achieve high speed, consistent. But now that PDF files can be used to global newspaper ads transmission, why not in other publications get more extensive application? In order to find out the reasons, we need to know the value of PDF and widely used in PDF existing in what some obstacles. PDF in many fields has a high application value; this is because PDF has many characteristics. Including device independence (PDF and not use platform), page independence. In addition, PDF has a free casual reader with cross-platform support. Equipment page independence is one of the -key factors. In the automation degree increased today, requirements of different equipment in a different environment on display, the output of the same file. For some of incompatible PDF format, we can use PDF to ePub software to convert PDF to ePub for some special demands.

Although PostScript has as many output center accepted formats, but the format for each device are required to install the corresponding software. PostScript neither support page independence, nor in the final document preview or choose a single page. Full PDF files including all of the font information and image information. Additional, if have a good color management agreement, then it can be in different platforms such as Macintosh, Windows and the Unix see the same file. This makes PDF become soft proofing in content on color even a ideal format. Although like Adobe PageMaker, Illustrator and Photoshop and so on some application allows users to save or export to PDF file format, but this is not people imagination of native application documents. Until now is not a kind of application allows to PDF documents are complete in operation. The recently released page design and application software Adobe InDesign declared the local of PDF page program files can be applied directly to printing.
