  • CD duplication Sydney service then creates a master made of glass which has a photo-sensitive layer. All of the customer’s information is then engraved on this master glass with the help of a laser light. As a safety security, CD duplication Sydney service engraves a special IFP number on each disc of glass that it produces. The next step involves application of a fine coat of silver by vacuum evaporation.
  • Once the master glass is ready it is transformed to a mould; a nickel layer is added through electrolysis. The next step involves the removal of the nickel layer from the glass so the CD negative can be recovered. This negative is known as the stamper of the CD and by repeating the above steps, more masters can be made and the whole process repeated.
  • Once the mould is ready, liquefied polycarbonate is injected in the mould. Within a few seconds a CD is created containing the required data.

The last phase of making the perfect CD is the printing of the label. This can be done either through offset printing or silk screen printing, in different colours.
