The special aniline dyes for making the master image came in the form of ink or in pens, pencils, carbon paper and even typewriter ribbon. Hectograph pencils and pens are sometimes still available. Various other inks have been found usable to varying degrees in the process; master sheets for spirit duplicators have also been pressed into ...
A spirit duplicator (also Rexograph and Ditto machine in North America, Banda machine and Fordigraph machine in the U.K. and Australia) is a printing method invented in 1923 by Wilhelm Ritzerfeld, which was used for most of the 20th century. The term "spirit duplicator" refers to the alcohols that were the principal solvents used in generating ...
The hectograph introduced in 1876 or shortly before, was a technology in which a dye-impregnated master copy, not unlike a spirit master, was laid on top of a cake pan full of firm gelatin. After the dye soaked into the gelatin, sheets of paper could be laid on top of the gelatin to transfer the image.
Unlike spirit duplicators (where the only ink available is depleted from the master image), mimeograph technology works by forcing a replenishable supply of ink through the stencil master. In theory, the mimeography process could be continued indefinitely, especially if a durable stencil master were used (e.g. a thin metal foil).
The as-yet-unknown chemical composition of the ink has made this particular scroll easier to read through X-rays, but scientists believe it may contain one particular ingredient. Defying gravity
Supertank printers are a type of continuous ink system (CISS) inkjet printer.Supertank printers differ from traditional inkjet printers in that the printhead is connected via a tube system that draws ink from large ink tanks built into the printer, which are filled and refilled via ink bottles, eliminating the need for ink cartridges.

Ink was forced through the stencil (originally by an ink roller), and it left its impression on a white sheet of paper. Until this time, any "short copy runs" which were needed for the conduct of a business—e.g., for the production of 10–50 copies of contracts, agreements, or letters—had to be copied by hand.
