This is an ancient document! I wrote this document in late 1997. I make it available because some of the techniques still retain some relevance.
Raster Image Processing, or RIPping, refers to the conversion of a PostScript file to a high-resolution bitmap, a necessary process in typographic-quality printing. In high-end printing, RIPping is performed by the PostScript interpreter that resides in a laser printer or filmsetter.
Here you can access four brief documents that introduce you to RIPping, in order to get a document from a Macintosh to a commercial printer:
Rip out your TrueType fonts!
Submitting raw PostScript to a print shop
