Hello Philippe,<br>
|
||
<p>
|
||
I think that you mean "descreen". This is to get rid of the<br>
|
||
nasty pattern that you get when scanning a magazine or<br>
|
||
newspaper image. It is caused by the dots that make up the<br>
|
||
image interfering with the scan.<br>
|
||
<p>
|
||
If you are using GIMP as your image processor, there is a<br>
|
||
descreen filter in "Filters -> Enhance -> Despeckle" that<br>
|
||
will go the job.<br>
|
||
<p>
|
||
If you don't have GIMP, you can try softening the image if<br>
|
||
your backend drivers supports it, or for a last resort, try<br>
|
||
this:-<br>
|
||
<p>
|
||
Carefully (!!) place a suitable sheet of glass on the scanner<br>
|
||
bed and put the image on top of that. Scan as usual. The glass<br>
|
||
will slightly defocus the image and remove the pattern. Be very<br>
|
||
careful not to scratch the scanner's own glass!!<br>
|
||
<p>
|
||
Regards<br>
