<p>[QUOTE="gsalexan, post: 1145266, member: 24274"]I've always been envious of the quality of your scans. Now I see how much experimentation you've done. My biggest problem has been <i>moiré</i> patterns (pronounced moray, for those unfamiliar). These are the geometric patterns you get when the fine lines of an engraving are picked up by a scanner that scans in fine straight lines, but slightly askew. You get interference patterns like the one below. Sometimes very interesting but not usually welcome.</p><p><br /></p><p>I usually scan at 200 dpi, but it sounds like you use 300 dpi and then resize -- correct? I think I've still had this problem occasionally even at that resolution.[/QUOTE]</p><p><br /></p>
