I am using the very difficult MpixPRESS software to order business cards. When I Personalize, Insert Object, and my image which I designed in Photoshop at 2x3.5" appears, it is smaller than the canvas size. Shouldn't it fit neatly? When I stretch the image to fit and then preview, it looks grainy.

Is there a business card template available that I can use in Photoshop. I don't like the idea of stretching my image.
 

Why don't they use ROES for press products? It would be so much easier. I am about to give up.
