What is a glassmaster ?
A glass master, also referred to as a 'stamper' is used to punch all of the data pits into a CD or DVD during the process of replication.
The reason why it is called a glass master is because the information is copied onto a special chemical coating on a circular block of glass. The block of glass is actually much larger than a CD (they are typically 240mm in diameter and 6mm deep) to facilitate handling and to avoid the sensitive data area from being touched or damaged.
The glass master is polished until it is ultra smooth as even microscopic scratches can affect the quality of the CDs being produced.
Glass mastering is performed in a Class 100 clean room (10 times cleaner than an operating theatre). A Class 100 cleanroom is designed to never allow more than 100 particles (0.5 microns or larger) per cubic foot of air (typical office building air contains from 500,000 to 1,000,000 particles per cubic foot of air). This is because dust, pollen and smoke particles can all affect the quality of a CD glass master whilst it is being prepared, so the mastering facilities are kept as clean as possible.

Silver or purple DVD ?
The colour of the back of a standard DVD-R, where the data are burned, is generally purple or dark blue for DVD-RW. With replication the back of the DVD is silver. The minimum quantity of disc required for a replication is 500 units. That means, you will not be able to have silver DVD if you wish to produce from 1 to 499 DVD discs.

For black thermal printing, please provide vectorised artwork, format Illustrator AI or EPS. For colour thermal printing, provide a JPEG.

Why customise blank media ?
We are one of the few companies in the UK to offer Custom CDs and DVDs. Custom CDs can be ordered as blank data CDs or as a cheaper alternative to full-print CD duplication.
For blank data CDs/DVDs, the basic idea is to replace standard blank discs, which you have to write on with a CD pen, with CDs/DVDs pre-printed with your company names, logo, job number or description. It is a popular choice for companies who wish to transfer their data to a set of CDs/DVDs that can be neatly archived with clear labels. It is also popular with individuals who wish to store their work on distinctive discs and for students, bands and filmmakers who want a more cost effective alternative to standard CD/DVD duplication along with company workers who wish to submit work in a stylish fashion.
For those still afraid to have their own customised CDs/DVDs as an alternative to standard CD/DVD, here are some of the reasons why having your own pre-printed CD or DVD can be advantageous:
Data Security: Data, which has been stored on a CD/DVD, cannot be changed and is permanent. Data stored on a floppy disc can be altered without any sign of a change being made.
Self-Promotion: Most blank CDs/DVDs either have a totally plain face or are branded with the manufacturer's logo. With your own custom printed CDs, your name and logo will be on the disc face. This helps to project a professional image and promotes your name.
The professional touch: Ask for clear plastic wallet, C-shells or paper sleeves. Very cheap disc protection, they will add a professional finished to our CD/DVD.
