I'm looking to use Wal-Mart's digital photo printing services to print out some new coin reject inserts.
I've attached one of the images I'd like to use. AFAIK, it's to scale.
Wal-Mart told me their machine outputs @ 900 DPI. However, I'm sure that their software will try to scale the image to fit their scale. This image is 801x1902, and I think that it'll rescale based on resolution of 640x480 (and up, 800x600, 1024x768 and up are the same scale)
How can I make sure I get an image (printed on 3x5 stock) that's going to be the correct size? I tried doing this with just one slot, and they blew it up to 3x5 (it should be less than 1x1) and turned it green!
