You’re going to lose a lot of quality if you do that; do you not have the original Illustrator/Photoshop file?

I agree with richard here. I would start with a template that that you can set to the correct DPI and then copy your business card design over to it. When you increase the DPI, it tends to make your designs look like crap.

What program are you doing this design in?

To echo the above, bumping the resolution up won’t satisfy this requirement or improve its quality. Photo-like images (JPEGs, TIFFs, and the like) can’t be scaled up. Photoshop would have to “guess” at what information goes in the empty spaces between the existing pixels you’re enlarging, and it simply can’t do a good job.

I’m guessing you’re trying to use a Windows screen resolution graphic (96 dpi) for print (typically 300 dpi, I’m surprised at 180). If this is your original art, you’ll have to rebuild it from scratch at 300 dpi.

@pupntaco- I designed the businesscard for a theatre group. They gave me no information but what they wanted on the card and their ideas. After I submitted the design they sent me back an email saying they need it to be minimum 180 dpi in order to have them printed.
@bodyhead- The program I am using is called Photo Explosion SE. Not many people have heard of it/use it that I have come in contact with.
