Understanding EPSON TWAIN Pro Features / Using the EPSON TWAIN Pro Main Dialog Box

Selecting a Destination

Destination list
Destination button

The Destination setting allows you to specify the application or the output device for which the scanned image is intended. Use the Destination list to select a predefined or user-defined destination, or use the Destination button to customize Destination settings.

Destination list

Select a predefined or custom setting from this list. The predefined settings have the Resolution and Unsharp Mask values shown in the following table.

If you are using an EPSON Stylus printer and are printing scanned images with the Economy, Normal, or Fine Print Quality settings in your printer software, selecting EPSON Stylus Printer (Fine) is recommended. If you are printing with the SuperFine or Photo Print Quality settings, select EPSON Stylus Printer (Photo).

Note:

The effects of the Destination settings cannot be viewed in the Preview window.

Destination button

The Destination button opens the Destination dialog box, where you can change Resolution and Unsharp Mask settings and add your custom settings to the Destination list, as described below.

To save the settings you made, type a new name in the Destination Name box, and then click Save. To delete a custom Destination setting, select the setting name then click Delete.

To apply your settings, click OK. To cancel the settings, click Cancel.

Destination Name

Predefined and custom setting names appear in the Destination Name list. Select a setting from the list, or save new custom settings by typing a name in the Destination Name box, then clicking Save.

Resolution

Specify a scanning resolution for line drawings and halftone images, and for photos. You can select one of the dpi settings available in the list box, or you can type your own setting in increments of 1 dpi up to 6400 dpi. The maximum resolution available is 12800 dpi.

Note:

When the Pixel Depth setting in the Image Type dialog box is set to Black & White, the Drawing/Halftone settings take effect. For other Pixel Depth settings, the Photo settings take effect.

When making Drawing/Halftone settings for printer destinations, make the Resolution setting the same as the resolution specified in the printer driver. When making Photo settings for printer destinations, specify a Resolution setting between 150 and 300 dpi. Selecting a resolution higher than 300 dpi slows down printing without improving the output quality.

The Resolution setting is closely related to the Image Size and Scale settings. If you change them arbitrarily, the resulting image may not be what you expected.

Unsharp Mask

The Unsharp Mask feature improves the sharpness of the scanned image. You can choose between four Unsharp Mask settings: Off, Low, Medium, and High. Selecting High improves image sharpness the most, but may cause your software to work more slowly. You can see the effects of your settings in the Preview window.

Unsharp Mask Off
