The
Resolution
setting, measured in dpi (dots per inch), controls the amount of
detail captured in your scans. Increasing the resolution raises the
amount of detail captured but comes with the following
disadvantages:
- Larger file sizes
- It takes longer to scan your originals, send/receive
your scans by email or fax, and to print your scans
- The image may become too large to fit on your
display or print on paper
If you plan to enlarge a scanned image so you can
print it at a larger size, you may need to increase the resolution
from the default resolution set by Epson Scan 2. Follow these
guidelines to determine the resolution setting you need:
-
You will scan
the image at its original size but enlarge it later in an
image-editing program.
Increase the Epson Scan 2 Resolution setting in your
scan. Increase the resolution by the same amount you will increase
the image size to retain a high image quality. For example, if the
resolution is 300 dpi (dots per inch) and you will double the image
size later, change the Resolution setting to 600 dpi.
-
You will scan
the image at 100% or a smaller size.
Select the Epson Scan 2 Resolution setting based on
how you will use the scanned image:
-
Email/view on
a computer screen/post on the web: 96 to 200 dpi
-
Print/fax/convert
to editable text (OCR)/create searchable PDF: 200 to 300 dpi
