ABOUT JPEG COMPRESSION

Scanned graphics, photos, and other images can sometimes produce large ﬁles. The JPEG options for scanning reduce the ﬁle size by compressing the image electronically. But compression also reduces image quality. Therefore, compressing an image involves a trade-off between image quality and ﬁle size. In many cases, loss of quality due to compression is not readily apparent, but the amount of compression you select—if any—depends on the quality you want.

The JPEG compression options only apply to:

■Destination applications used for graphics, photos, and artwork images. Word processing applications, fax applications, and other text-based destination applications do not use JPEG compression.

■Scan modes for color or grayscale scanning. JPEG compression does not apply to the Black/White scan mode.

Note: You can add JPEG compression to the existing preset conﬁgurations if the destination application is for graphics, photos, or other artwork images.
