Hi, I've just finished working on a web development project and the company who it is for have asked me to provide them with all the graphics I have used so that they can use them on literature, signs and maybe even on there vans. I've spent most of the day re-creating them in adobe illustrator so that they are in a vector format and are easily re-sizable without distortion. My question is what format am I best to save them in. Is there an industry standard? For instance what format would a sign maker need the logo in to print it. Will the illustrator (.ai) simply be ok?
