r Tip: As a rule of thumb for any image except line art, use scanning resolutions that are one third of your output resolution. For example, use a scanning resolution of up to 110 with a 300 dpi laser printer and up to 170 with a 600 dpi laser printer. For the color EPSON Stylus printers, choose a resolution from 100 to 240 dpi for 720 dpi output and from 100 to 150 dpi for 360 dpi output. r Tip: For printing on a commercial printing press, multiply the lines per inch (lpi) the press prints by 2 to determine your scanning resolution. For example, if your lpi is 150, try scanning at 300 dpi. (If the file size is too large, multiply the lpi by 1.5 to determine the scanning resolution.) r Tip: If you plan to enlarge an image when you print it, scan it at a higher resolution than you normally would. Selecting a calibration profile Use the Calibration pull-down menu to select a predefined or custom calibration profile that matches your output device. TWAIN can then use the profile as it scans to create the best quality image. EPSON TWAIN provides the following predefined calibration profiles: General Screen Impact Dot Printer Thermal Printer Inkjet Printer Laser Printer Laser Printer 600 Stylus COLOR IIs Stylus Pro Stylus Pro XL Stylus 1500 Stylus COLOR Stylus COLOR II Stylus COLOR 200 Stylus COLOR 500 Capturing Images From Within Applications 3-15

Tip:
As a rule of thumb for any image except line art, use scanning
resolutions that are one third of your output resolution. For
example, use a scanning resolution of up to 110 with a 300 dpi
laser printer and up to 170 with a 600 dpi laser printer. For the
color EPSON Stylus printers, choose a resolution from 100 to
240 dpi for 720 dpi output and from 100 to 150 dpi for 360 dpi
output.
r
Tip:
For printing on a commercial printing press, multiply the lines
per inch (lpi) the press prints by 2 to determine your scanning
resolution. For example, if your lpi is 150, try scanning at 300
dpi. (If the file size is too large, multiply the lpi by 1.5 to determine
the scanning resolution.)
r
Tip:
If you plan to enlarge an image when you print it, scan it at a
higher resolution than you normally would.
