Each time an image is saved as JPEG, some information about the image is lost, even at the
highest quality (and lowest compression) levels. This effect is compounded if you save a file,
then make some changes and save again. So if you plan on editing or otherwise modifying your
images at a later date, JPEG isn't the ideal choice
Instead, use TIFF, which stores all of the data of an image without any loss, even when
compressed. TIFF is a good choice for archiving files, and for image operations in image editing
applications like Photoshop(TM). The downside of TIFF is the file size. Even when compressed
the files are much larger than JPEGs.
Burn TIFF files to high quality CD-R or DVD disks for permanent archival
Reduce Crop | Preview area (p. 68) on flatbed scanners to improve scan times
A lot of time involved in scanning is taken up with the movement of the scan head (for flatbed
scanners) or the media holder (for film scanners). The following tip will produce quicker scans.
Position the media in landscape orientation on the scanner (place the long edge of the photo,
for example, against the short, bottom edge of the scanner). This reduces the area that needs to
be covered by the scanner head.
Scanning text from paper for use with OCR software
To get the best results when scanning printed documents, set Input | Media (p. 50)to "Text".
This will ensure the result is limited to black and white, which will reduce noise. Typically OCR
packages expect TIFF file format; set Output | TIFF file (p. 82). You may also find the Output |
TIFF multi page (p. 82) and Output | PDF multi page (p. 85) option useful, as multiple pages will
be saved in a single file.
Turn off rotation if scanning with limited memory
If you save images that are significantly larger than the amount of memory on your computer,
set the Input | Rotation (p. 56) to None. This will make the cropping much faster.
