Hectograph - Citizendia

The hectograph or gelatin duplicator or jellygraph is a printing process which involves transfer of an original, prepared with special inks, to a pan of gelatin or a gelatin pad pulled tight on a metal frame. Printing is a process for reproducing text and image typically with ink on Paper using a printing press Gelatin (also gelatine, from French gélatine) is a translucent colourless brittle nearly tasteless solid substance, extracted from the

The special aniline dyes for making the master copy came in the form of ink or in pens, pencils, carbon paper and even typewriter ribbon. Aniline, phenylamine or aminobenzene is an Organic compound with the formula C6H7N An ink is a Liquid containing various Pigments and/or Dyes used for coloring a surface to produce an Image, text, or A typewriter is a mechanical or Electromechanical device with a set of "keys" that when pressed cause characters to be printed on a medium 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 service. A spirit duplicator (also referred to as a Ditto machine or Banda machine) was a low-volume printing method used mainly by schools and churches (However, these are often unusable, since the spirit duplicator uses a "mirror image" on its master sheet. For the hectograph, the mirror image is on the gelatin itself. )

After transfer of the image to the inked gelatin surface, copies are made by pressing paper against it. When a pad ceased to be useful, ink could be sponged from the top of the gelatin and the pad reused for the next master. A grey-colored, thick, absorbant paper pad was supplied to cover the gelatin surface for storage. This also removed ink from the surface, but took many hours to do so. Care needed to be taken that the gelatin surface was kept clean, and not damaged during duplicating by one's fingernails. A nail is a horn -like structure at the end of an animal's Finger or Toe.

The gelatin process produced print runs of somewhere between 20 and 80 copies, depending upon the skill of the user and the quality of the original. At least eight different colors of hectographic ink were available at one time, but purple was the most popular because of its density and contrast.

Hectography, requiring limited technology and leaving few traces behind, has been deemed useful both in low-technology environments and in clandestine circumstances where discretion was necessary. In the earlier 20th Century, the process lent itself to small runs of school classroom test papers, church newsletters and science fiction fanzines. A fanzine (see also Zine) is a nonprofessional publication produced by fans of a particular cultural phenomenon (such as a literary or musical genre for the pleasure Prisoners-of-war at Colditz Castle during World War II used an improvised hectograph to reproduce documents for a planned escape attempt.

It has also been used, though not very extensively, as an artistic medium in printmaking. Printmaking is the Process of making artworks by Printing, normally on Paper. The Russian Futurists used it for book illustrations, and the German expressionist Emil Nolde made four hectographs. "Russian Futurists" redirects here For the band see The Russian Futurists. Expressionism is the tendency of an artist to distort reality for an Emotional effect it is a subjective art form Emil Nolde (7 August 1867 – 13 April 1956 was a German painter and Printmaker.

It also was used in professional situations; in Macy's advertising department during the 1950s and 1960s, full-page newspaper ad layouts were drawn with hectograph pencils and then duplicated on a hectograph to make file copies for future reference. Macy's is a chain of mid-range American Department stores Its Flagship store in Herald Square, New York City has been billed Before the popularization of spirit duplicators and the mimeograph, there were mechanized hectography machines which used a drum, rather than a simple flat tray of gelatin. A spirit duplicator (also referred to as a Ditto machine or Banda machine) was a low-volume printing method used mainly by schools and churches

In the final chapters of The Pothunters by P. G. Wodehouse the major characters use a jellygraph to produce a school magazine at very short notice. The Pothunters is a 1902 novel by P G Wodehouse. It was Wodehouse's first published novel and the first of several school stories this one set at the fictional Sir Pelham Grenville Wodehouse, KBE (15 October 1881 – 14 February 1975 (ˈwʊdhaʊs was an English Comic novelist who enjoyed enormous popular success Wodehouse assumes his reader knows exactly what a jellygraph is and alludes to its being unattractive: "This jelly business makes one beastly sticky. I think we'll keep to print in future. "

George Orwell's Keep the Aspidistra Flying (1936) describes a somewhat more subversive schoolboy publication:

And at that moment, in the years just after the War, England was so full of revolutionary opinion that even the public schools were infected by it. Eric Arthur Blair (25 June 1903 – 21 January 1950 who used the Pseudonym George Orwell, was an English writer Keep the Aspidistra Flying, first published 1936 is a grimly comic Novel by George Orwell. The young, even those who had been too young to fight, were in a bad temper with their elders, as well they might be; practically everyone with any brains at all was for the moment a revolutionary. Meanwhile the old--those over sixty, say--were running in circles like hens, squawking about 'subversive ideas'. Gordon and his friends had quite an exciting time with their 'subversive ideas'. For a whole year they ran an unofficial monthly paper called the Bolshevik, duplicated with a jellygraph. It advocated Socialism, free love, the dismemberment of the British Empire, the abolition of the Army and Navy, and so on and so forth. It was great fun. Every intelligent boy of sixteen is a Socialist. At that age one does not see the hook sticking out of the rather stodgy bait.

While the hectograph process is almost entirely obsolete for printing on paper, it's still used for making temporary tattoos on human skin. A tattoo is a permanent marking made by inserting ink into the layers of Skin to change the pigment for decorative or other reasons Tattoo artists use hectograph pencils to draw pictures on paper and then transfer them to the recipient's skin.
