note 48140 added to function.imagecreate

I am running into a resolution issue. I am using this function to create an image from an existing PNG graphic for clients to print off gift certificates that they purchase, and we send via email. The problem I found is that, although the image we create from is 120ppi resolution, hte PHP code creates the new image at 72 ppi, thus decreasing the print quality greatly. Anyone know of a way you can change the resolution of the newly created images?
