Graphic design printing covers a vast scope of services. Any graphic that is printable falls into this area. You as an average consumer need to be focused in order to get what you want.
First of all know what your focus is going to be. Are you shooting for a holiday theme or a general graphic that is pleasing to the eye? What is your demographic? These two questions will lead you in the right direction so that you can make the most of your campaign.
Next, you need to know what your medium is going to be. Do you want a full tri-fold brochure, a flyer, or will a postcard do it? This will help you to keep the number of graphics to an optimal level without overloading your printing piece.
Lastly, be honest with yourself. Do you need to hire someone or at least look to an online printer for templates and tips? Getting in over your head will most likely lead to a waste of your hard earned dollars.
