CD Duplicator Companies
As the price has decreased on CD duplication and printing equipment in recent years, it has become quite an affordable operation for even small businesses. CD duplication and printing equipment of near professional quality can be had for only a few thousand dollars which is more than enough for smaller printing runs in groups of 10 or 50. That’s all well and good unless you are facing an emergency mail out consisting of 1000 CDs by tomorrow. What do you do then? Or what if your customer expects you to exactly reproduce their brand colors? Ink jet print can’t usually handle that. It is times like these that call for you to outsource the job and hire a professional CD duplication company. At high volumes, the cost of outsourcing the work is probably on par with running the job in-house because of the economies of scale that larger duplication facilities benefit from. Lead times are shorter (most professional CD duplicators can turnaround an order in a day or twp) and the print quality is much better too. There are lots of these companies around, so it makes sense to make use of them. Because of the rapid expansion of the internet, many of these duplication companies advertise online. The intense competition often leads to some large advertised discounts. Since costs are probably being cut somewhere by a company that offers the lowest deals, it would be wise to ask for a sample. Not only does this give you a good idea about the quality of the work, you will get an idea of the kind of customer service you will receive. The duplication facility will need you to provide a template containing the artwork. Most suppliers place available downloads on their websites. Be sure to submit the any desired fonts, converted into outlines if possible. High resolution PDF or EPS are the preferred file formats. If this is too confusing, the professional CD duplication company’s artwork department can often guide you through the process for an additional reproduction charge. CD duplication companies are experts in the field of reproduction, and that’s what they do. It should therefore be noted that they will most likely not check the material on the master you send them. If you are duplicating an audio CD, be careful not to send them a data CD containing WAV or MP3 files. Quicktime or WMV files are also often sent instead of DVD video discs. It is always a good idea to check the master before sending it out to be duplicated. The duplication company will assume you have already done so.
