The light source can be an actínic bulb internal or external to the device It consists essentially in a flat glass on which the original photolith is placed in direct contact with the surface (paper, film, plate) to be exposed, with a pump for creating a vacuum around both (optional), and a light source (actinic UV tubes in the case of offset and PCB manufacturing) making use of an automatic timer (optional).〔 == Uses == This contact copying process that was used in the early photography days, it is also used, among others: in silkscreen printing, in ''blueprint'' copying, in the CTF offset printing processes and in the PCB manufacture. The contact copier comprises a source of intense light projected through a photolith film that only lets light pass through in clear areas (those not printed). Silk frames, offset plates or PCB, are usually impregnated with a photosensitive material (varnish type) which reacts with light that modifies its surface characteristics. Subsequently, some portions of the photo-sensitized varnish may be removed, leaving the final product ready for use . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Contact copier」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
