CD duplication refers to the process of making an exact replica of the original. Sometimes, only a few tracks of the original are used and the rest are duplicated. This process is very similar to replication of a CD. Most of the times, the duplication is done to CDs that are meant for promotional purposes.
The tools used
The copying and replication process is based on using the exact tools needed to make a CD, only if they have the master copy. If not, the same tools will be used that are needed for CD replication. The replication process is usually done with the help of a glass master or a stamper. This stamper must be made by a manufacturer and should be a duplicate of the original. It should also be smooth and should have no scratches. The stamper should also be very thin. Another tool used is the “Raster to Vector” or R2V. This tool should be used when working with the master and the replica. It can also be used when making stampers for the CD.
The copying process is done with the help of a copying machine that isfitted with a software. The same software can be used when making copies of Audio CD and producing labels from them. A computer can also be used along with that. The CD can be copied using a USB flash drive or by using a CD writer. The required amount of data to be encoded on a CD needs to be calculated.
There are many such CD duplication techniques that have been discovered and they are discussed below.
1. Using of another Copy Machine
An audio CD duplication / replication house can do the job of making many duplicate CD’s but they prefer not to do it this way. They do it all from the CD master.
replication is the process of copying the data from a master onto the discs themselves. The replication house will take the master, repair any damage or reversions and then replicate those copies onto the CD’s themselves. This method is usually used for mass production of CD’s.
3. Mastered from master
This method is similar to replication but instead of replication the master is repaired first so the data that is present on the master is replaced by the results of the repair.
4. Post Production
Sometimes the repair job needs to be made further and this is done when the dialog and effects are changed or when live action is added to the copied material. The cost of this is usually charged extra because data is left from the master which needs to be replaced.
5. Quality control
The audio duplication facility is run well below the quality standards. There are a number of reasons for this and these are day to day things done to ensure that the quality of the copied material is as high as possible. These include normal wear and tear of CDs whilst being handled. In this case, the master is scanned to obtain the required data.
6. Using software
This method is recommended for copies that are made without the master. The software does not need to be perfect as the purpose is to remove the errors from a master.
Among the errors that appear on a master are scratches, warping and bad cover art. These need to be fixed or restored on the CD while using the master.
This is the most important test for duplicating a CD. The colors on a master are very important; they define the tone of the music and can determine if the copied CD will have problems printing.
9. renowned duplication professionals
This is a field where experienced professionals do not copy masters but they can make a copy if needs be.
10. pinch at the center of the disc
In order to make a hole in the disc, the needle and the tool must be used. Apieceof the disc must be stretched in order to make a hole. Care must be taken to avoid damaging the master on the CD.
11. label maker
Not all CD comes with a label maker but music discs do come with such devices. These are important if you want to write on the disc.
12. matter of tune
The music CD that you make should have a tune you can hear. You can make a mistake if you do not write the tune on it.
You need to understand that all the above services are provided by a professional company and you need to be aware if you are hiring these services. This is the reason why there is plethora of companies that can be found online.
Who would want to buy a blank music CD?
Very few people. Why? Unlike CD’s, which are mass produced and sold by big companies, blank music CDs are not produced by big companies. Therefore, not many people(imize) them.
