Here are some recommended settings for different types of scans.
1
If your final output is for on-screen viewing (for example, on a web page), select 72 dpi for your
resolution.
2
If you are enlarging your image, you must manually increase the resolution (dpi) proportionally to
maintain the resolution of your original.
3
If you are scanning between 1201 and 2400 dpi, EPSON recommends you keep your scan area
to 4
×
11.7 inches to maintain true hardware resolution. Above 2400 dpi, you will be using
software interpolation to increase the resolution.
PressWriter for iMac does not have a TWAIN scan function,
but you can import a scanned image from another application
using the Object, Import Image function.
