Frequently Asked Questions About Duplicating Machines and Supplies The following are some frequently asked questions about duplicating machines and supplies:
What is a duplicating machine?
Duplicating machines were designed to reproduce existing texts and, in some cases, images. Duplicating machines were able to create large quantities of paper copies cheaply and relatively quickly, so they were especially popular among businesses like self-publishers and schools. For the most part, duplicating machines have now been replaced by photocopy machines, scanners, and laser printers.
What kinds of duplicating machines are there?
There are several kinds of duplicating machines. There are mechanical ones, like mimeo machines and ditto machines, that rely on physical equipment and supplies to function. These machines require an operator in order to function. There is also a digital duplicating machine. This device depends on both physical and automated parts.
How do mechanical duplicating machines work?
Generally speaking, mechanical duplicating machines require stencils. A mimeo machine uses a wax paper stencil, which has the document stamped into it, that is wrapped around the drum of the device. Black ink is forced through the stencil and onto fresh paper. The ditto machine, or spirit duplicator, uses two-ply master sheets of paper. The first sheet of paper has the text written, typed, or otherwise transcribed onto it. The second sheet of paper has a thin layer of colored wax on it. The pressure from creating the words on the first sheet causes the second sheet to transfer wax. This is similar to carbon paper, but the text produced with a ditto machine will be reversed. The wax image is then attached to a drum and is used to make copies. The major advantage of ditto machines is that they can print in multiple colors.
How do digital duplicating machines work?
Digital duplicating machines are very similar to mimeo machines. The major difference is that digital duplicating machines are automated, so an individual does not need to manually create the stencils and run the equipment. A scanner is used to view the text or image, and a stencil is made using this scan.
