Scanning Images - Epson Expression 636 Easy Setup Manual

You'll select different resolutions for scanning line drawings and
halftones from the ones you select for scanning photographs.
The final output device is the device on which you plan to
ultimately print the image. This may be a printer connected to
your computer or a commercial printing press.
In addition, the file size of the scanned image may determine the
resolution you select. The file size may be very large for high
resolution scans, taking up valuable disk space and causing
longer processing and printing time. Generally, the higher the
resolution you choose, the larger the file.
Note that a very high resolution scan may not produce a better-
quality printed image because your output device may not
recognize the high resolution information stored in the file.
There is no point in scanning at a higher resolution than your
output device can support. To keep file sizes manageable, select
the lowest resolution that provides acceptable quality on your
output device.
You can change resolutions using EPSON TWAIN by choosing
the Destination button on the advanced screen. In the
Destination dialog box, select the box beneath the resolution
type you want to change ( Drawing/Halftone or Photo ); then
choose the resolution for that type from the pull-down menu.
Now that you know the basics, you're ready to begin scanning.
For additional information, see the manuals for your scanner,
the scanning utilities, and your software.

Scanning Images

Now you're ready to start scanning. First, choose an image to
scan. The best choice is a color photograph. Printed pictures,
such as those in magazines, do not scan as well as photographs
because of the dot patterns used in the printing process.
