Etching is a type of engraving that became widespread at the end of the 16th century. When creating an etching, the mechanical method of processing the board with various engraving tools is replaced by the chemical etching process. This engraving type applies to the gravure printing technique. Durer, Rembrandt, Renoir, Kramskoy, Shishkin and many others performed in this technique. Working in etching, it is possible to achieve a great variety of strokes.
