Book excerpt: Computer technology has completely revolutionized the work of graphic designers, printers, and print production professionals. To keep pace with these far-reaching changes, Production for Graphic Designers is set firmly in the digital age. This revised fourth edition embraces all the new and emerging technologies in graphics and print production, comprehensibly explaining the prepress and printing processes from traditional letterpress to the latest on-press CtP (computer-to-plate) digital offset and on-demand colour printing. It also covers new workflows and spells out the many acronyms encountered by today's designers. As well as covering print, it provides an authoritative guide to working in digital media, particularly the internet. There are also additional feature spreads on key graphic designers Bruce Mau, Paul Rand, Chris Ware and Pentagram.
