SCANNING FROM WINDOWS 98, ME, 2000, OR XP 39

■ Halftone—scans the image so it appears to consist of gray tones.

A pop-up menu appears so you can choose one of the halftone

options. Notice that the preview image changes as you select each

option so you can see which one is best for scanning. Halftones

produce simulated gray tones by using black and white pixels of

different sizes and is often used to produce newspaper and

magazine images. Use this setting for lower resolution black and

white images. The halftone settings also produce small ﬁle sizes.

■ 8-Bit Gray—scans the image using up to 256 true shades of gray.

Use this setting to scan black and white photographs and other

higher quality black and white images. You can also scan a color

photo with this setting to turn its colors into gray shades. The ﬁle

size is about one third the size of a color scan.

■ 24-Bit Color—scans the image in full color. Use this setting to

scan color photographs and other color images. The ﬁle size is the

largest of the image type options.

■ Enhanced bit-depths—If you are using an imaging application

other than PaperPort, the image type drop-down list will include

16-Bit Grayscale and 48-Bit Color. These image types are only

available if the imaging application supports them. You will

receive an error message if the application does not support the

selected enhanced bit-depth.

RESOLUTION

Resolution determines the amount of detail you can see in the scanned

image. The resolution setting for a scan is in dots-per-inch (dpi). The

higher the resolution, the ﬁner the details, however, higher dpi settings

also take longer to scan and produce larger ﬁles sizes. Higher settings are

typically used for precision work, such as photographs or ﬁne artwork.

■ Click the Resolution drop-down list and select a resolution.

The resolution settings on your Visioneer 9750 scanner range from

100 dpi to 2400 dpi.

Halftone Example

Note: You can see the ﬁle size at the bottom of the Scan Manager.
