Design is not created by software. Decoration can be created with software, not design. Anyone can learn how to use software, however, this does not create graphic design. Services that offer super-cheap “design” services for say $99, well, they will be nicely decorated, but not truly designed.
True graphic design is much more. It requires an understanding of the goal. An understanding of a company and who they are. What they would like to accomplish. Then, a designer will create solutions that work in print, online, on mobile devices and anywhere else people experience communications. An experienced designer will work closely with a company to create communications that speak to people.
Speak to people with ideas that illuminate.
