Logo Design Tips
[ 1 ] If it wasn't created with at least 300 dpi, printing it will be painful.
[ 2 ] If it wasn't created with CYMK in mind other then RGB, it wont print the correct colours or tones.
[ 3 ] If its a bitmap to start with then resizing for other uses on packaging etc will be a pain.
[ 4 ] If it was a vector artwork, it could be resized to any size without too much fuss.
[ 5 ] Once you have developed it this way, save it as an EPS and then rasterise when required.
[ 6 ] The font and size compared to the background will make it very difficult to reduce its size to something very small as you will lose too much information when doing so and the text will be virtually impossible to read.
