Here’s a lingo tip about resolution. Although images can have a resolution from 1 to more than 2,000 ppi, when it comes to talking resolution, there are three basic resolutions that are pretty common. Low-res (short for resolution) is normally 72 ppi, and low-res images are primarily used for onscreen viewing (such as the Web, slide presentations, digital video, etc.). Medium-res is generally 150 ppi and is commonly used for printing to inkjet and laser printers. When people use the term high-res, it’s almost always referring to 300 ppi, which is more than sufficient resolution for printing to a printing press. Anything above 300 ppi is still considered high-res, but you’d say it like this: “I made a 600-ppi high-res scan.” Which resolution is right for you? Nice try. That’s a whole book unto itself.
