I feel stupid for asking this question, but need to know the answer to it. My cousin asked me to design some stuff for his new company and I was wondering what program I should design them in? Should I use InDesign or just Photoshop (or Illustrator?...) The main reason I'm asking this is because I don't know how he is going to get them printed. How do printing companies go about doing that? If in Photoshop, what resolution should I use? Sorry for being a rookie, haha.
