Too many times I've had a new client come around that doesn't have a usable copy of their logo. And most of the time, they don't have a way of contacting the original designer. This can prove to be both time consuming and costly to recreate the logo.
The problem is, most people don't really understand what versions they need of their logo to preserve it.
Many people think that as long as they have a JPG they can stick into Word or an email, all is fine. Or if their logo is on their website, they can store it there for the future. Unfortunately, these are raster images, and can not be enlarged, and often not printed correctly.
We all know that good logos are not cheap, so to protect your investment make sure your designer provides you with an Illustrator EPS (vector) file. And hold on to it safely! You will probably not be able to open it, but thats OK. These EPS files enable your logo to be enlarged infinately, and printed professionally.
Two more things to know about your logo. Make sure you know what fonts were used to create the logo. The designer might not be able to provide you (legally) with the font, but he or she should be able to direct you as to where to get it.
Know your color palette. The logo designer should design using the Pantone (PMS) colors. So, for example, your logo colors could be PMS 295 and PMS 185. Also, if you can, hire your logo designer to create a "brand book" to dictate how to use the logo, so you can pass on the guidelines to future designers.
So now I ask, my dear (few?) readers. Do you know where your logo is?
