An etching process in which the resist is applied to the metals surface by photographic means.
An intaglio process in which the etching plate is coated with a light-sensitive acid-resistant ground and exposed, through a dot screen, to a photographic image. A "negative" resist dissolves in the areas that are exposed to light, while hardening in areas not exposed to it. Thus pits are etched and ink is held in the areas that appear light in the photographic image. A positive resist dissolves where it is not exposed to light.
A process that uses chemical or machine etching to remove material from a metal. This produces small parts with much higher detail than can be obtained through injection mould ed plastic. Photo etch parts are common after-market products.
Printing process using an acid solution to etch a photograph onto a metal surface.
an intaglio printing technique where a metal plate (usually copper) is exposed to photographic film under ultraviolet light. during this process, the clear parts of the image are hardened onto the plate and act as an acid resist.
An intaglio image printed from a plate on which the depth of the etch is constant. Tonality is controlled through the size of the dots, as in offset.
A printmaking technique in which a light-sensitive metal plate is exposed to photographic film under ultraviolet light. (Jewelry) A metal etching technique in which a pattern is painted onto metal and the metal is then exposed to acidic chemicals, which etch the uncovered areas.
