What is the mimeographer?
Mimograph is a duplicating machine used to produce copies by pressing ink through the template holes and on the sheets of paper. This type of machine is also known as a machine for template, Mimeo or Mimeograph. There are different kinds of extraographers, including one drum and dual drum versions, and can be driven by an electric motor or hands rooted for the production of copies without the use of electricity. Mimograph invented Thomas Edison at the end of the 19th century and the mimeograms were widely used in offices, schools and similar environments until the end of the 1960s, when they were replaced by other duplicating machines such as photocopies and offset printing. Mimoography is unusual today, but some users are still preferred because they are cheap, reliable and simple.
The table used to produce copies in the mimograph is a flexible sheet made of coated material, usually some type of wax paper. Create a document to be copied, the template material can be inserted into the mechanicalType typewriter without ink. Entering each letter and then strikes the holes in the material and create a template. Stylus or other sharp implementation can also be used to create images and other types of patterns on the template material.
The oldest extraographer invented by Edison was a platform version, but soon it was replaced by extraographers using rotating drums or cylinders. In one of the mimographic, the finished template is wrapped and attached to the cylinder, which was saturated with an ink. Copies are made as a cylinder rotation, pushing the ink holes in the template and on the sheets of paper that pass off with extraographic. In the double drum machine, the template is connected to the silk belt, which covers two cylinders. When it spins, the rollers apply ink to the cylinders and the ink is pushed through the silk screen and the template of paper sheets to create copies.
In one color mimographic, multicolored images can be created by turning off the cylinder PRO one saturated with different color ink. Today, photocopies, laser and inkjet printers and other types of printing devices and duplicating processes have largely replaced the use of extraographers. However, the mimeograms are still used in some developing countries because they are cost -effective and easy to make copies, and also because manually clicks can also be used in areas where there is no access to electricity.
