摘要:
A reflex-type digital offset printing system includes four single-pass, single-color digital imaging systems arranged along a print medium feed path, and an image server that utilizes a positional clock to implicitly synchronize the imaging systems with the movement of a print medium along the feed path such that single-color (e.g., black, cyan, magenta, or yellow) image portions can be successively superimposed to produce a full color image. Each single-color digital imaging system utilizes a digital micromirror device and an anamorphic imaging system to generate a high energy, one-dimensional modulated line image that selectively evaporates fountain solution from an imaging cylinder before ink material is applied. Each imaging system utilizes a sensor that sends a respective drum position signal to the image server, and the image server utilizes the drum position signals to synchronize the single-color printing operations with the position of the printing medium.

Duplicating equipment is provided for printing on both faces of the same sheet or, in the alternative, making two impressions on the same face (e.g., in different colors) by means of two printing heads. Both printing heads are served with masters from a single supply point, the masters being fed in proper order and attached to the master cylinder of the appropriate printing head automatically. In one form of the invention, the single master supply point takes the form of a single master maker and converter.
摘要:
A duplicating arrangement which includes a copying machine for copying an original and an offset printing machine operatively connected to the copying machine for producing prints from a master copy. The copying machine and the offset printing machine are both constructed so as to be independently functional modules with an automatic control device being provided for controlling the operation of the copying machine and offset printing machines such that, depending upon the duplications to be made, the duplicating arrangement feeds a copy from the copying machine to either a depository or the offset printing machine, wherein the copy so-forwarded serves as a master copy in the offset printing machine.

An office copy type of machine is provided which photoelectrically copies an original document, makes an offset printing master therefrom and thereafter is used to print with ink as many copies on ordinary paper as are desired.
