Tiari's right... and there are a couple of other considerations, too.... when Photoshop changes size or resolution, it does a resample, which tends to be why you get "jaggies".... you can use photoshop to increase the resolution up to a point before things start to go wahoonie shaped... I don't know what your output format is, but if you have an option, (Via the printer), to output as a file, you will be able to set the DPI... On the side, not many seem to have noticed, but 72 pixel is the default setting for Photoshop. Lou.
