In interpretative engraving the engraver does not attempt to slavishly reproduce the drawing before him but rather interprets the picture because of technical reasons, as is the case in woodcuts, because of his fantasy, or even because he lacks the necessary skill. An example of a technical reason for interpretation is the copying of a wash drawing which can hardly be copied faithfully using only lines. Line engraving in which the lines cross in an oblique pattern forming lozenge shapes. Original engravings are those in which the plate or block was made by the same artist who drew the design. A technique which results in values using only dotted work.
Metal engraving usually on zinc plates using a sand let and a stencil.
Generally speaking stipple engravings are characterized by little hollows or dots on the plate which are used to create half tones. The stippling can be done in a variety of ways. A woodcut which renders a drawing done with a brush. In order for the woodcut to do this there must be a certain amount of interpretation. Such engravings are meant to be printed on a printing press.
