You should always think of any image, as a collection of dots. On the web, these are called pixels, which is a single unit of color, or a colored dot. In the print world, these dots are also called pixels, or dots. A screen can only display 72 pixels, per inch, whereas in the print world, you can put as many in as you can fit. The standard tends to be 300 pixels per inch, or dpi (dots per inch) for textbook quality. However, the more dots, the better the picture, and the bigger you can stretch it out.
