Digital business card printing there are basically two types of laser and ink-jet, laser has been stable, screening is quality of color and ink-jet equipment there is still room for development. In addition to the Kodak Versamark use continuous inkjet technology, and the remaining ink-jet business card printing devices that are using on-demand inkjet (drop on demand) technology, and the most microtecnic inkjet head manufactured concentrated in Spectra, Xaar, Epson, Toshiba Tec, panasonic, and so on one of the few manufacturers to strive to find the full study on the next version of the technology, to attack and occupy more market field.
