Tell from the principle, sculpture of laser form of intaglio printing is application all the way or multichannel is high-energy stimulate beam of light, in platen surface await sculpture data (metallic layer or base lacquer layer) on, ablation gives ink cell or the ink cell appearance that show copper, form ink cell printing plate directly, or machine ink cell ready-made for sequel.
From above the fundamental that gives out can know, this included two kinds among them slightly discrepant carves a technology. The first kind is to use high energy laser to carve platen metal surface directly, form ink cell of form of intaglio printing. current technology level, layer of direct sculpture copper has not scored a success. Swiss Daetwyler company adopted the compromise method that carves zincic layer, achieve goal of its laser carven. The 2nd kind is besmear first on cupreous platen Fu black base lacquer layer, with area of laser ablation ink cell, the cupreous layer that makes ink cell is in is bare come out, blame ink cell is in by base lacquer protection fights corrode, wait for after corroding, can obtain sunken the ink cell below. Although go up from fundamental,both difference appears and not quite, but analyse from the detail such as ink cell feature, process, both still have distinguishing feature each.
