I am fairly new to photoshop. I currently have Photoshop 5.5 and I am having a problem with blurriness around my text. My printer seems to think it is because my publication may not be in 300 dpi. I scan all pictures in 300 dpi but still get the blurriness around the edge of my text. It looks chopy. How do I change the entire publication to 300 dpi?

If the text was rasterized at a low resolution, upsampling to 300ppi is not going to look good. Since Photoshop is not a page layout program, it is important that the text be entered at 300ppi from the start.

When you open a new file what resolution are you specifying?

What kind of publication? How many pages? How much text? Output to what kind of printer on what kind of paper? At what resolution did you save your files?

Generally, photos and contone images will do fine at 266-300dpi. Text (real text, not special effects text from Photoshop) is different. If you have much, it should be set in a layout app(PageMaker, Quark, or InDesign) or an illustration app (FreeHand, Illustrator). Rasterized text (ala Photoshop) will never print as sharp, even if you are saving your files at 300dpi. I think the minimum for resonably sharp raster text is about 800dpi. It depends on the printer, and honestly, it doesn’t sound like yours knows much about this.
