84 Scanning Using the Document Table
❏ 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.
Click the arrow next to the Resolution list and select the number
of dots per inch at which you want to scan. See the table below
for some guidelines:
After selecting the Resolution, you can preview your image and
make any necessary adjustments. See "Previewing and Adjusting
the Scan Area" on page 85 to continue scanning.
