• CTP = digital automation of the prepress process
• skips traditional image-to-film-to-plate workflow by
going directly from digital image creation to platemaking
• significant potential for cost savings: no more
consumable film, light tables, rubylith, goldenrod, etc.; no more
strippers!
• CTP platesetters do the RIPping and plate imaging
• CTP platesetters are 2-, 4-, and 8-up devices that use
metal plates with silver- halide, photopolymer, or thermally activated
imaging properties
• most CTP plates require photochemical processing after
exposure; a few are "processless"
• there's also "CTP on the desktop" from paper and
polyester plates imaged with toner in standard desktop laser printers
(for small-format, short-run work only)
