Use Descreen to minimize the appearance of unsightly
interference patterns (moire patterns) which may occur in your image
file when scanning original documents created by a halftone process.
With Descreen you can minimize the transfer of moire patterns
into your image file and avoid the checkered, banded, or dotted
appearance.
When you apply Descreen filter, the effect is applied
to the whole image, and you cannot apply it to the selection.
- To apply Descreen filter, drag the slider to a position that suits the
type of document you scan. When the slider is in the leftmost
position, no descreening will be applied. Dragging the slider to the
right increases descreening effect to be applied to the scanned image.
When you scan high-quality art prints, select the position next to the
leftmost. To scan the images from glossy magazines, drag the slider to
the right to until you reach the position preceding the rightmost one.
To scan the coarse images like newspaper photos, drag the slider to the
rightmost position.
- You can also use spin buttons to adjust the depth of descreening
effect. To increase descreening, click an arrow pointing up. To
decrease descreening, click an arrow pointing down.
