This article explains how PostScript is interpreted and output. The diagram below gives a basic overview: PostScript data are generated from a layout application when the operator wants to print a job. The data can be sent directly to device with a built-in interpreter, such as an inkjet printer, or the data can be sent to a dedicated RIP that interprets the data for one or more devices such as a platesetter or an imposition proofer.
Learn more about PostScript errors on this page or dive into the database of known errors. If your problem is not listed, try these workarounds. PostScript related sites It seems logical that Adobe is the best place to look for information about PostScript.
After all they invented the stuff. Aandi from Quite Software seems to be all over the Internet, offering valuable information on several Usenet newsgroups, as well as mailing lists.
His website also contains useful stuff including a chapter about PostScript errors. Also check out their software, they make some pretty interesting plug-ins for Acrobat. The Inkguides PostScript page is another excellent pointer to other sources of information. Brian Huebert maintains an excellent jumplist that also deals with web design at www. Highly recommended! So it can be practical to have another RIP available in case of postscript errors: Adobe Acrobat is a must have for every prepress professional.
Acrobat Professional is a suite of programs which includes an application called Distiller. Distiller really is a RIP so you can send your troublesome page to Distiller and double check whether it can handle your file. This is still kind of a PostScript file but structured in a different, more robust format.
This PDF can then be opened in Acrobat to preview the content on a screen. You can also make small corrections to the file and either print it or export it back to PostScript.
It is available for Mac, PC, and Unix. Here are some of them: Adobe Acrobat. Enhanced by some of the available plug-ins, it is a very powerful yet cost effective tool to manipulate PostScript files. Jump to the PDF section of my site to learn more about it. It is far beyond me to try and do major modifications in a PostScript.
But for some problems it is useful to just take a look at the code and delete or add a bit. BBedit is a popular editor for Macintosh. There is a free version of it called TextWrangler which you can download from the same site.
This is a great editor that runs on various flavors of Windows. PostScript downloaders Nowadays PostScript downloaders have largely become irrelevant. Most RIPs either have a manual upload mode in one of their menus or you can upload files by dropping them in a hotfolder. Newsletters It took some time to find an actual PostScript related newsletter but I finally found one and it is great: Books Thinking in PostScript This book gets mentioned first, not because it really stands out although it is an excellent introduction to PostScript but because you can download it for free for Macintosh at least.
Once this publication went out of print, its author Glenn Reid had the great idea to put it on the net as a PDF document. This huge volume contains everything you want to know about PostScript and more.
It is written with the programmer in mind but can be useful for learning about PostScript or getting to know what the command that is causing that awful PostScript error actually does. A PDF version of this book can be downloaded from the Adobe website but you can still buy the printed version.
