As a graphic designer, depending upon your step upon the ladder, you
will be involved in the brain storming of ideas from the client brief;
you'll be responsible for the development of the ideas into a design
and then see this through to a print ready piece of work.
You might be working on graphics for a poster, a brochure, a
leaflet, a company's brand, signage, websites, CR-ROMs etc. Your skills
and talent can be turned to any task.
A basic common skill set for a graphic designer should include:
Quark, InDesign, Photoshop, Dreamweaver, Illustrator, Flash as well as
any other relevant languages which would be of benefit.
