"Faux Italic" in Photoshop!
I have been doing some print work lately and I once accidentally used the "Faux Italic" feature in Photoshop. It looks great when you look at it at 100% on a hi-rez display, but it often doesn't print well. It is not an issue when working for web graphics. In the Character palette, you want to make sure you select "Italic" from the "Regular" dropdown instead of clicking on the "Faux Italic" icon. What I understand is that the "Faux Italic" option exists for fonts that don't have a true Italic version.
