Selecting the Scan Resolution
In Professional Mode, you can select the resolution you want at
any time.
Before you select the scan resolution, you should consider
whether you will enlarge the images, and if so, whether you will
enlarge them before or after you scan. Follow these guidelines:
❏ You will not be enlarging the images.
If you will scan the images at 100% size or smaller and will
not enlarge them later, you can accept the Resolution setting
selected by EPSON Scan based on your original and
destination settings.
❏ You will enlarge the images as you scan them (increase the
Target Size setting).
If you will enlarge the images in EPSON Scan so you can use
them at a larger size, you can accept the Resolution setting
selected by EPSON Scan based on your original and
destination settings.
❏ You will scan the images at their original size, but then
enlarge them later in an image-editing program.
If you plan to enlarge your images later in an image-editing
program, you need to increase the Resolution setting to retain
a high image quality after enlargement. Increase the
resolution by the same amount you will increase the image
size. For example, if the resolution is 300 dpi (dots per inch),
but you will increase the image size by 200% in an
image-editing program, change the Resolution setting to 600
dpi in EPSON Scan.
