precision embossed metal

Traditional metal packaging, such as this tinplate (tin-plated steel) biscuit tin, is printed first and then embossed. High quality reproduction is achieved, because the registration between the offset lithographic print and the embossing is very precise (metal is stiff and so can be very accurately registered in the tool). Pressure is applied to form an indent, known as deboss, or a raised surface profile, known as emboss.
