Descreening prevents moiré patterns and consists of two operations:</p> <ul> <li>Screen removing.</li> <li>Reducing a halftone moiré pattern.</li> </ul> <p class="text_pl">Unlike most scanners which apply blurring to remove a screen, the plug-in Descreen uses the Fourier transform to automatically find parameters of a screen and precisely removes it. Due to that the plug-in preserves more image details. There is no need to scan images at different angles and to resort to other time-consuming tricks. You need just provide the plug-in with a hi-resolution scan, usually 600...1200 pixels/inch.&nbsp;&nbsp; </p> <p> <script type="text/javascript"> <!-- function nothing() { return; } function img_on() { document ["sample_noise"].src = "images/descr_sample1.jpg"; }; function img_off() { document ["sample_noise"].src = "images/descr_sample0.jpg"; }; // --> </script> <img class="noborder" src="images/descr_sample0.jpg" onmousedown="img_on()" onmouseup="img_off()" onmouseout="img_off()" name="sample_noise" width="400" height="418" alt="The image before descreening" /><img class="noborder" src="images/descr_sample1.jpg" width="400" height="418" alt="The image after descreening by plug-in Descreen" /></p> <p class="text_pl">On the left is an original image.
