Er.. sorry guys, but DPI/PPI is not your problem. The bottom line is, I guess Tara's clients are going to commercial print, and virtually ALL commercial printers still refer to DPI. (A lot have still only moved over from hot metal to PC's, they are a rather backward bunch.) Most standard printing runs at 150DPI, but for higher quality, they may run to 300, or even higher for brochures and posters. In a nutshell, I think you are up a gum tree here. If you do print work, run at least at 150DPI. It's always best to ask what the final destination product is here anyway. Upping the image res size in increments will help to a degree, as it gives PS a better chance to interpolate the pixel data, but as one chap said, you can't make an image create detail if it is't there already. I think you have to put this one down to experience, and start over. Sorry.
