I have an icon that is 32 pixels square and looks great on the screen. I want the same graphic as a logo on a business card. My mockup card looks great both on the screen and printed at home, but when I gave the printer my graphic, they said they couldn't use it because it is too small.

I'm using PhotoImpact. For my business card, I created a new image at 72dpi that is 3.5 inches by 2 inches. That translates to 252x144 pixels. Then I copied my logo graphic which is 32x32 pixels and pasted it as an object in my card image. When I print my card, the logo is 10 mm square (or 7/16 inch square) on the 3.5 x 2 inch card. That looks just right. When I print the logo by itself, it's 32 pixels square (just barely a dot).

What do I need to do to make the logo the right size? How do I get it from 32 pixels to 7/16 inch? How do I avoid pixelation of diagonal lines when I make it bigger? It's a solid color with a transparent background.

Thanks!
