What is electrotype printing?
electrotyping, electroforming process for making duplicate plates for relief, or letterpress, printing. The process was first announced in 1838 by M.H. von Jacobi, a German working in St. Petersburg, Russia.
What electrotype means?
Definition of electrotype 1 : a duplicate printing surface made by an electroplating process. 2 : a copy (as of a coin) made by an electroplating process.
What is electrotyping in chemistry?
Electrotyping (also galvanoplasty) is a chemical method for forming metal parts that exactly reproduce a model. The method was invented by Moritz von Jacobi in Russia in 1838, and was immediately adopted for applications in printing and several other fields.
How are electrotype coins made?
The electrotype process, frequently used during the 19th century, involves electroplating a thin layer of metal on one face of a mold. The shell, which duplicates the side of the original coin being copied, is removed and other metal is placed inside to strengthen it.
What is the meaning of electroplating in science?
Electroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode.
What is a coin Electrotype?
An electrotype is a copy of a coin made using a process similar to electroplating. Usually, the counterfeiter makes a copy of the genuine coin that he can work with so as not to ruin the original.
What is the main principal of electroplating?
What is the main principle of electroplating? Electroplating is the method of depositing one metal over another in the presence of a metal salt (in aqueous solution). The water molecule is released as the final product in this process. As a consequence, electroplating is based on the theory of hydrolysis.
What is the Hindi meaning of electroplating?

What are electroplating industries?
Industry Description and Practices Electroplating involves the deposition of a thin protective layer (usually metallic) onto a prepared surface of metal, using electrochemical processes. The process involves pretreatment (cleaning, degreasing, and other preparation steps), plating, rinsing, passivating, and drying.
