Hi Ondrej<br>
<p>
<i>&gt; I have just discoverd that when I scan under 300 dpi with my</i><br>
<i>&gt; UMAX Astra 1200S I get faint vertical stripes in my image. </i><br>
<i>&gt; Sometimes. Moiree Pattern?</i><br>
<p>
Moriee Patterns are only possibly if you scan something that is<br>
printed. If you take a real photography and the stripes go away,<br>
I think it is a moiree-effect. If you have this stripes with a<br>
photograhphy, too, it is not a moiree-effect.<br>
<p>
The scanner itself does everything to get the right resolution,<br>
the driver has nothing to do with it!<br>
<p>
Bye<br>
Oliver<br>
