The scanning pixels are all the same size and are either black or white. Use this setting for letters, memos, pen and ink drawings, and other black and white material. This setting produces the smallest file size for scanned items. • 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. 36 DocuMate 520 Scanner Installation Guide
