Recommended Resolutions to Suit Your Purpose

Resolution indicates the number of pixels (smallest area of an image) for each inch (25.4 mm), and is measured in
dpi (dots per inch). The advantage of increasing the resolution is that the details in the image become fine.
However, it can also have the following disadvantages.
❏ The file size becomes large
(When you double the resolution, the file size becomes about four times larger.)
❏ Scanning, saving, and reading the image takes a long time
❏ The image becomes too large to fit the display or print on the paper
See the table and set the appropriate resolution for the purpose of your scanned image.
