* If you use brightness or contrast in the above two cases, you actually reduce the amount of information collected
from the original, but gamma collects more information in dark or light areas and less in the opposite type of area.
Scanning text for OCR
If your OCR result is not satisfactory, it may be
because the original is unclear. First, adjust the
brightness. For bolder text try -10, for lighter, try
+10. With this you can increase the contrast a little
for bolder text or decrease the contrast for lighter.
Scanning line-art drawings
If parts of lines fade out after scanning, you can
reduce the brightness and/or decrease the contrast in
much the same way as for scanning text. Similarly if
you find that scanned lines appear bolder (fatter),
reduce the brightness and/or increase the contrast.
36-bit Color Mode
Your scanner is capable of scanning images using 36-bit color depth. This provides a more dynamic color and tonal
range, giving your scanned images a smoother and more colorful appearance.
The 36-bit color mode is disabled by default because currently only a few application programs such as Adobe
PhotoShop can accept 36-bit image data. When disabled, your images will be scanned in 24-bit color mode. To scan
images in 36-bit color, simply enable
36-bit Color Mode
in the Color Options menu.
