While Postscript is fine for print jobs it poses special problems to the screen-oriented designer.
Postscript is one of the most elegant and powerful pieces of software ever developed.
It's a much over-used word in this industry, but PostScript really did revolutionise printing, and the way people think about output. In a screen-oriented age, like the one that the Web is creating, having smooth curves and the ability to print on all sorts of printers is less important than legibility. PostScript is vector-based, the Web is bitmapped. However to get a PostScript file to render nicely for the Web still means knowing a little voodoo, and having the right tools to hand. For example, instead of there being a nice conistent format for PostScript files we have these ugly things called EPSs to deal with.
