-----What is DPI?-----
DPI, or dots per inch, relates to the concentration of color dots used anywhere an image is displayed in pixels or dots. Essentially, a higher DPI yields a higher image resolution. DPI is also important in retaining quality when resizing an image. When imaging documents, DPI becomes important for the following reasons:
You should get picky with DPI if you're scanning images that will need to be printed in a high quality later on. For simple text documents, a lower DPI will be just enough, but for scans from magazines or photographs, a high DPI will be essential to the print quality of those images. A high DPI is also necessary to make your document text-searchable. DPIs of 200 or higher make text recognition available.
