| Contone Photorealistic Desktop DOD Ink Jet Processes
In contrast to continuous ink jet printers, this liquid ink jet printing technology only generates an ink droplet if it is to be ejected onto the substrate to form a dot, thus the terminology: drop-on-demand (DOD), or impulse jet print. The printhead on most desktop printers employs piezoelectric crystal technology to eject the ink droplet. DOD printers can also have thermal printheads that use the formation and collapse of a bubble due to heat to eject droplets. Example A: Epson PhotoEx Other Given Names: Contribute to this category! Dates: Contribute to this category! Colorant: liquid dye-based ink Medium: very wide variety. Contone media are either RC based or have a receptor coating. Uncoated paper can be used as well, but results in a less brilliant image (Figure III). Surface: matte to glossy, paper fibers hidden Inscriptions: Epson Photo Paper (RC paper) has the words "EPSON Photo Paper" in gray diagonal letters on the verso. Contribute to this category! Formats: Contribute to this category! Image Quality: at 1440 dpi print resolution near photographic quality, to the naked eye almost indistinguishable to photographic prints (Figure I). Under magnification individual dots are sharp, but render near continuous tone Applications: desktop printing, graphic arts, advertising agencies
