DocuTech
DocuTech is the model name given by Xerox Corporation to an electronic production-line publishing system. This system integrated Xerox-branded scanners, processing software and production printers to produce a single workflow solution for digital publishing, and is credited with helping to start the print-on-demand industry.
With its ability to scan, edit and archive books for later retrieval, and output stitched or tape-bound books, the DocuTech 135 (DT135), introduced in 1990, was arguably the first fully-integrated "on-demand" publishing system. This system was capable of scanning and then printing black and white pages at up to 135 pages per minutes (for letter or A4 sizes) with a resolution of 600 x 600 dots per inch (dpi). The system could also print on sheets up to 11x17 inches (or A3 size). Another feature of the first system was it's ability to perform signature imposition and generate 2-up signatures in the proper page order.
The DocuTech 6135 is an improved version of the DT135, with a Sun Microsystems workstation controller replacing the original controller and scanner. Additional improvements include an optional VLD laser assembly, increasing the print resolution to 600 x 1200 dpi.
The DocuTech system's main competitor in the field of print-on-demand production plant is IBM's InfoPrint system.
