Abstract

While conventional xerography can be used to generate high quality monochrome printing of computer output information, this technology has not yet offered a simple solution to the problem of multi-color computer printing. The need for multi-color computer print is real. Computer generated output is frequently displayed as a multi-colored image on a video display terminal and the information from such displays can be lost if the hardcopy is only monochrome. Also, even for computer output which is primarily monochrome, the availability of highlight color would be beneficial.

While conventional xerography can be used to generate high quality monochrome printing of computer output information, this technology has not yet offered a simple solution to the problem of multi-color computer printing. The need for multi-color computer print is real. Computer generated output is frequently displayed as a multi-colored image on a video display terminal and the information from such displays can be lost if the hardcopy is only monochrome. Also, even for computer output which is primarily monochrome, the availability of highlight color would be beneficial.

As a solution to the above problems, proposed is a coupling of monochrome xerographic technology with multi-colored thermal ink jet printing. Each of these technologies offers important attributes; xerography is capable of producing high quality monochrome images while thermal ink jet can produce multi-colored images from a compact print head. Thus, a tandem xerographic/ink jet (or ink jet/xerographic) arrangement would allow monochrome and colored printing to be produced using the marking technology best suited for each application.

Potential advantages of this hydrid approach include: 1) greatly reduced contamination problems between the black and colored marking modules, 2) greater flexibility in color production without a loss in throughput (e.g., use a multi-j...
