Document Summary

Require: imaging head, in some cases, an image transfer drum. Doesn"t require: printing plate or pressure like conventional does. Can produce variable sheets for variable data, direct marketing, personalization. Digital printing processes are generally better suited for shorter press runs: makeready is extremely short and very little spoilage/waste, typical run can range from 50 to 1000 sheets. Xerography: uses electrically charged dry toner particles and image transfer drum to create an image, e. g. Inkjet: uses highly fluid ink and print head to print directly on substrate, e. g. 1973 first xerographic computer printer, xerox 1200, introduced. 1976 first inkjet printer created by hewlett-packard (hp) 1980 daisey-wheel printer commonplace for computer output. Dot matrix printers: good for carbon copy forms. 1991 heidelberg and presstek introduce the gto-di with first platemaking on press. Static, non-variable, no separate plate making required. 1993 indigo launches the e-print 1000 digital press at the ipex trade show, indigo purchased by hp.
