Scanning from TWAIN Adjusting the Resolution Resolution determines the amount of detail you can see in the scanned image. The resolution setting for a scan is in dots-per-inch (dpi). The higher the resolution, the finer the details. However, higher dpi settings also take longer to scan and produce larger file sizes. If you are scanning photographs to make copies, 200 dpi will make a direct size copy of similar image quality to the original. You would use a higher dpi setting to enlarge a picture from the original size. To adjust the resolution: • To use one of the preset resolutions for typically scanned items, click one of the options in the list. • To set the resolution manually, drag the Resolution slider to the left to decrease the resolution or to the right to increase it. You can also click the up and down arrows to increase or decrease the setting. • Click Reset to return the resolution to its original setting. Some resolution settings for typically scanned items are: • Business Card or other items with small print - 300 dpi. • Color Page with graphics or color photographs - 200 dpi. • Email photographs - 100 dpi. • Text Document (for OCR) forms, letters, memos, or spreadsheets- 300 dpi. • Magazine Page with graphics, line art, or color photographs - 200 dpi. Advanced: The resolution panel also includes an advanced setting for Moiré patterns. Moiré patterns are wavy, rippled lines that sometimes appear on the scanned images of photographs or illustrations, particularly newspaper and magazine illustrations. To scan the image and limit or eliminate moiré patterns, select the Reduce Moiré option. This option is not available for high resolution settings. DocuMate 3640 71 User's Guide
