5 Types of Duplicating Machines

The stencil duplicator produced copies of letters, circulars, and pricelists simply but highly effectively. It used a stencil made of a coated fiber sheet through which ink was pressed.

The stencils could be printed in several colors. Unlike spirit copies, mimeograph stencils didn’t bleach to illegibility when exposed to sunlight.

  • Stencil Duplicator

Stencil duplicators are often used in schools and offices to produce notices, circulars, price lists, and more. They operate using a stencil that is fixed onto a rotating cylinder. When the machine is switched on, the copy sheet is moistened and brought into contact with the master stencil. This results in the transfer of a small amount of dye from the master to the copy sheet. The resulting copies are then glued together to form a finished product. Stencil duplicators can be manually or power-operated and are available under various brand names.

A newer type of duplicator is the risograph, also known as a ditto duplicator. The risograph operates much like a regular printer but can also process digital files from a computer or portable storage device. This makes it very useful for high-volume printing jobs. Like the stencil duplicator, it also uses a thermal printing system to create its images. It uses a heated drum with a screen that aligns with the image areas of the original to create duplicates.

Another advantage of a risograph is that it can be used to print in full color. However, it is not as durable as the other types of duplicating machines and requires a certain level of skill to use correctly. This is one of the reasons that it is more popular among larger businesses. Digital duplicators, on the other hand, are able to print in virtually any color and can also be used to print on heavy card stock, NCR forms, and envelopes of any size. They are also much faster than other types of duplicators and use minimal heat to attract powdered toner particles into the print area.

  • Multigraph Duplicator

Like the hectograph and mimeograph machines, the Multigraph duplicator works by forcing ink through a stencil onto paper. However, a Multigraph uses a perforated sheet of waxed tissue paper instead of the typewriter-type metal plates used by these earlier machines. As the drum of the machine rotates, a stencil with an image or text is pulled across it, and ink is transferred to each page of paper to produce multiple copies of the same image or document.

As well as a lower cost per copy, digital duplicators also have the advantage of printing on a much wider range of stocks, including envelopes and light cards. This makes them a popular choice for schools and churches that need to make high volumes of low-cost copies. Digital duplicators are also far more environmentally friendly than traditional office photocopiers as they do not emit Ozone nor use a cooling fan to circulate toner dust when the filter becomes clogged and have negligible power usage in standby mode.

The Multigraph was the first of a series of mechanical devices that took advantage of the second Industrial Revolution (which started towards the end of the 19th century). Other machines to take advantage of this included the Roneotype and Flexotype duplicators.

Modern digital duplicators are designed to look just like a standard multifunctional copier printer and can be easily integrated into the same office environment. They are incredibly easy to operate and have a much faster print speed than conventional photocopiers, meaning you can get your copies quickly and efficiently without waiting. Additionally, a digital duplicator can print in virtually any color you choose, requiring no drying time for each new page. This also means that you can save a lot on ink costs as you don’t need to worry about buying separate colors of ink.

  • Photocopier

In today’s world, the photocopier has become an essential office tool. It works by using a scanner to scan an image of your document, and then, with the help of light, mirrors, drums, and static electricity, it produces a perfect copy of that image on paper. This incredible feat of technology allows us to print incredibly high-quality documents, and it’s also very useful for businesses that want to keep their information secure, such as financial or healthcare companies.

A modern copier is quite complex, but the basics are simple. It has a photoreceptor drum covered in a special layer of semiconductor material, such as selenium, silicon, or germanium. This drum is given a positive electrical charge, and corona wires transfer that charge to the document. This creates an electrostatic field, which attracts toner particles to the document. The toner particles are just dry plastic fragments and pigments that color the document.

To make a copy, the master sheet is fastened to the drum. The toner is then transferred from the drum to the copy sheets, which are slightly moistened with an alcohol-based liquid. The copy sheets are then pressed against the master sheet, creating a reverse image of the original document on them. This method is very fast and can produce multicolor copies in a single run.

Unlike the stencil duplicator, this type of machine is capable of producing multiple copies very quickly. This makes it an ideal choice for preparing circulars, price lists, reports, and other documents that need to be distributed quickly. It can also be used to make high-quality color copies and black and white ones.

  • Electronic Duplicator

Digital duplicators combine mimeographic technology with current electronics. They are commonly found in schools, offices, and other workplaces that require large volumes of copies and prints. They can produce up to 190 copies per master with high-speed printing. They can also print on a variety of paper, light cards, and envelopes.

The original document to be copied is placed in the duplicator’s tray. The machine then scans the image and prints it onto a stencil (master) using a thermal print head. This process can be done in a few seconds or minutes. The master is then wrapped around a drum that contains ink. The ink is pushed through the stencil holes as the drum rotates. The stencil is then pressed against paper, envelopes, or light cards to create copies and prints.

These machines do not use photoreceptive drums or heated fuser units, allowing them to produce higher-quality documents with less power consumption and longer service intervals than the previous types of duplicators. In addition, one bottle of ink can last much longer than a typical printer cartridge.

Adding new ink and stencils to a digital duplicator is no more difficult than installing a replacement toner cartridge into a photocopier. And because the ink is contained within a chamber, there is no risk of spillage. Moreover, the cost of a new stencil or master is divided amongst all the copies and prints made, so the break-even point for additional copies is far lower than with a toner-based copy machine. This is a great investment for businesses and schools that need to make many copies of a single document. The RISO Digital Duplicator is manufactured by the RISO Kagaku Corporation and sold in over 190 countries.

  • Laser Duplicator

With an advanced rotary digital duplicator, you can quickly make a large number of copies in just a few minutes. This machine is ideal for businesses with high printing needs, and it produces higher-quality prints than other machines. It also offers more features than other types of duplicators, including USB plug-and-print capability. This makes printing documents saved on a thumb drive easy, which helps you save time. It’s also faster and more efficient than traditional duplicators, making it a great choice for busy office environments.

The stencil duplicator, also known as a mimeograph or mimeograph machine, is the oldest type of copying machine and still has a following among some enthusiasts. It uses a stencil made of a coated fiber sheet through which ink passes. The stencil is fastened to a cylinder that rotates, and ink is applied to sheets of paper fed under the cylinder. The original document is placed on top of the inked sheet, and a roller applies pressure to make a copy. The copies can be enlarged, reduced, or made the same size as the original document.

Another duplicator that is similar to the stencil duplicator is the hectograph. It uses a master that resembles carbon paper and is inserted into the machine with its back (inked) side facing outward. It works like a photocopier, but it does not use heat and instead relies on the pressure of the roller to make a copy.

The photocopier is a more modern duplicating machine that uses a scanner to digitize an image and a print cylinder to apply ink to paper. It can be used to produce copies in different colors and is much faster than other types of duplicators. The photocopier is also more environmentally friendly than other types of duplicating machines.
