Correct format for Logos
Posted by jane - December 5, 2011
Do you get confused about your logo? Do you have a jpeg version of it, but when you send something to be professionally printed they ask for an .eps version? I shall endeavour to explain.
Any logo should be created using Illustrator, this can then be saved as an .ai or .eps.
Illustrator is used because it creates a Vector file. A Vector file can be enlarged ad infinitum, so can be used for signage, as well as for business cards.
This is different to Photographs, which if enlarged above 100% of its actual size will degrade, and look pixelated. This is why digital cameras have now improved to allow for high resolution images. This is where jpegs and tiffs come into their own.
It is further complicated because anything printed offset litho needs to be 300dpi (dots per inch), in order to produce anything of reasonable quality, whilst anything on screen needs only to be 72dpi, and most laser or inkjet printers can produce reasonable quality at 150dpi. An Illustrator or Vector file (.ai or .eps) does not cause any of these problems.
However the problems have occurred over the years since Microsoft Word has been used more and more, and that won’t accept Illustrator files!!! It likes jpeg’s or png’s.
And lets not even start talking about CMYK (that offset litho uses) and RGB (that everything else uses!)
Ideally whenever a logo is created by a Designer, two sets of files should be supplied. One set for offset litho printing, these will be either .ai or .eps; and a second set for use in Microsoft and Digital (web etc), these are usually jpegs.
Hope this helps, it is very complicated and doesn’t help that people can’t actually see what a .ai or .eps file looks like, unless they have the right software!
If you are still confused give me a call and I will try and explain further.Comments Off
