by adding toned shades of gray in regions between black and
white. The copy modes are described in the table below:
2d-sharpening, 2d-softening, and 2d-blur
Through your software, you can manually set and control
sharpening, softening, and blurring filters, giving you rich
possibilities for combining effects to obtain perfect enhancement
results.
For example, you may have an image with details (such as text or
lines) you wish to sharpen. But if the image also contains large
concentrated areas of colors or graytones, sharpening will make
unwanted noise to appear in the scanned image. By using the
sharpen filter together with the blur filter, you can get the sharp
edges you need without creating the side effect of unwanted noise.
Both filters can be set at different levels for ultimate control of effects.
The B/W Copy Normal scanning mode incorporates 2D-Auto edge
enhancement, with automatic, on-the-fly sharpening of your image.
