A CD ROM or CD Audio is made from plastic and has an aluminium coating. The digital information is applied in the form of a spiral track onto the plastic. What are known as 'pits' are formed on the upper side of the CD during the injection moulding process (also called "pressing"). These are microscopic little bumps and indentations on the plastic. The reflective aluminium layer enables the laser beam of a CD player to subsequently read this "mountain-valley landscape" from below and convert it into audio or data signals. The CDs have still to be printed of course. Using silkscreen or offset processes we print text, images or graphics onto the CD - creativity knows virtually no bounds. We will be glad to show you samples of particular printing techniques. All the lacquers and colours guarantee a high level of durability.
