The mimeograph printing process used anink-filled cylinder and ink pad. In contrast, the dittomachine used no ink. The user typed, wrote, or drew on aditto master sheet which was backed by a second sheet ofpaper coated with a dye-impregnated, waxysubstance.
A ditto machine was a primitive photocopier thatused a solvent like methylated spirits or ammonia totransfer ink from the master copy (the template, if youwill) onto other pieces of paper. The solvent eithersoftened or melted the ink so that just enough of it wouldstick to the blank sheets of paper.
Alcohols were a major component of the solventsused as "inks" in these machines. The spiritduplicator was invented in 1923 by Wilhelm Ritzerfeld. Thebest-known manufacturer in the United States was DittoCorporation of Illinois, hence that name.
Digital duplicators, in a way, borrow ideas fromthese technologies to create a modern-day ink-printing machine. Themaster is then wrapped around an ink drum. The drum, filled withink, squeezes ink out through the tiny holes on the master. As thedrum rotates, it rolls over paper, leaving the image on thepaper.
The Gestetner is a type of duplicatingmachine named after its inventor, David Gestetner(1854 – 1939). During the 20th century, the termGestetner has been used as a verb—as in Gestetnering.The Gestetner company established its base in London, filingits first patent in 1879.
A spirit duplicator (also referred to as a Dittomachine in North America, Banda machine in the UK orRoneo in France and Australia) was a printing method invented in1923 by Wilhelm Ritzerfeld and commonly used for much of the restof the 20th century.

Advantages Of Photocopiers
- Convenience- A photocopier offers a fast and easy way ofgetting single or multiple copies of documents.
- Cheap and Quick- The basic advantage of a photocopier is tomake copies of documents quickly and cheaply.
- Improves Functionality- These machines have increased thefunctionality of many businesses.
A photocopier plays an important role inevery office. Because these photocopiers don't utilize thesame printing system with the desktop printers, it is certain thatthey do not use costly inks used by desktop printers and also, theyproduce copies a lot faster than usual printer's at largequantities.
The stencil duplicator or mimeograph machine(often abbreviated to mimeo) is a low-cost duplicating machine thatworks by forcing ink through a stencil onto paper. In thelate 1960s, mimeographs, spirit duplicators, and hectographsbegan to be gradually displaced by photocopying.
The hectograph, gelatin duplicator or jellygraphis a printing process that involves transfer of an original,prepared with special inks, to a pan of gelatin or a gelatin padpulled tight on a metal frame. The hectograph has beenmodernized and made practical for anyone to use.
Alternative Title: stencil duplicator.Mimeograph, also called stencil duplicator,duplicating machine that uses a stencil consisting ofa coated fibre sheet through which ink is pressed.
A photocopier relies on the principles ofelectricity and photoconductivity to work. There's alight-sensitive photoreceptor inside the machine that firstattracts and then transfers toner particles onto plain paper toform a copy of a document.
As nouns the difference between duplicate andcopy
is that duplicate is one that resembles orcorresponds to another; an identical copy while copyis the result of copying (confer original); an identicalduplication.A photocopier produces its output by creating adigital scan of an original and printing the result through thesame heat-set process used in laser printers. ARisograph, however, scans an original and creates a waxmaster based on the scan, printing copies from the master insteadof the scan itself.
