What on earth has smell got to do with graphic design?
It's a good question. For me, the 'smell' of a finished design is the overall impression it imparts. It's the coming together of type, imagery and colour to create something distinctive; something that can resonate and linger, just like a good wine or coffee.
One can't physically 'smell' a design (unless, of course, one used a scented paper stock to print it on) but just as a picture of freshly cut grass or wax crayons can evoke its smell, a good design can affect something deeper within us.
