ps was launched in 1984, for sending vector data to output devices like printers, imagesetters, and even slide/film recorders. it is a device-independent language. a page-description language. pdf, launched circa 1992, is PS, but ripped and viewed on your computer screen. pdf is human-facing, ps is device-facing. acrobat allows a soft-preview of a ps, viewable inside acrobat reader. at heart, pdf IS ps. only the use and purpose is more enhanced, and more human-facing. pdf is a wrapper around ps. when you send a pdf to a printing plant or production house, the pdf file is essentially ripped into films or plates, as a postscript file. > and eps is? > think of it as a clever way of nesting postscript data inside another postscript file. hence encapsulated postscript. > thanks in advance... > regards, bostjan hope this helps. :-) LL
