I am in the process of redesigning a postcard for a client and they need it so it can be printed at 300 dpi. I am doing this project in Photoshop and the only related option I see is ppi and I know that is for screen resolution. I know my graphic design terms, but I have to brush on my printing knowledge. Can someone fill me in real quick on how to get this document to be printed in 300 dpi? I will not be printing it; I am just redesigning it for them. Oh and they also requested the bleeding to be 1/16". I know this is possible in Illustator, but how would I do this in Photoshop? Thanks a bunch!
