I have a lot of personal bias about this particular topic due to my past experiences as a designer. In graphic design (or any design discipline for that matter) there is a very important question that we ask: does my design do the job that it was intended to?
The design of a band poster can look great aesthetically as a beautiful piece of art, but did it list the date and time effectively for the event? No? It’s not a good design. We’re artists, yes, but we have a very specific job to do and if we don’t address it, we’ve failed. Want to make a poster that is just aesthetically pleasing without any info on it at all? That’s a very different job that you’ve undertaken. You want a gorgeous print to sell. BOOM! You succeeded.
