To prepare the artwork for the Photo Chemical Etching engraving, we need a pattern or a drawing on paper, or in any of the following graphical formats: dwg, dxf (AutoCAD or other softwares that use these formats), 3dm (Rhinoceros), stl, igs, cdr (Coreldraw), ai (Illustrator), pdf, fh11, tiff, bmp, tga, eps and others. From experience we advice the technical designers to comply with the dimensional tolerances indicated here, and also to take into consideration that the type of material, the thickness and the shape of the piece can influence on the tolerances. Possible guaranteed characteristics will be pre-emptively accorded.
