Many people don’t realize it, but graphics that look great on the web will usually look horrible when they are used to print from.
The Tip
This is because a typical 72 ppi jpeg is great for displaying on your web page, but for your printing to look equally pleasing, it takes a 200-300 ppi (pixels per inch) or in printing terms 200-300 dpi (dots per inch) image to look good. As a side note, jpegs (or jpgs) are great for web use because the file size is very small and great for a quick rendering on the web, but are actually the poorest image choice to print from. Ideally tiffs are a much better choice for printing to maintain the best quality for continuous tone images.
